How to remove background from a video online, free
Start to finish: upload a short clip of a person, wait while the AI works, and download a transparent WebM, a green-screen MP4 or an alpha matte.
Free, no sign-up, no watermark: background delete free online for video, in full HD up to 1920 px.

No watermark on the free export. Transparent WebM, GIF or green screen, straight out: free exports go up to 1920 px.
What actually goes wrong
People drop in all sorts of files, and once in a while, one of them isn't actually a video the tool can decode. Over the 40 days before this was written, 4 uploads across the site came back with "No video track found in this file": often an audio file renamed with a video extension, or an export that lost its video stream somewhere along the way. It's a small number against the 96 times a named tool page here was opened in the same period, but it's the clearest real example of what actually trips people up, rather than a guess.
Most rejections are simpler than that: of the 189 uploads turned away in the same window, the overwhelming majority were straightforward limit checks, a clip too long or a file too large, not a mystery about the file itself. If your upload gets rejected here, the message on screen tells you exactly which of the two happened. It's built to be strict about size and length, and lenient about everything else.
Nothing to install
Most background removers want a subscription, stamp a watermark on the export, or only work if you already own a green screen. VideoBGNinja runs on our own GPU, so there's no cloud bill per clip and nothing to pay: it separates a person from any background frame by frame, free, with no account and no watermark.
Because it runs online, there's no desktop app, plugin or account: open the page, drop your clip in, and the processing happens on our GPU, not your laptop. That means it's the same whether you're on Windows, macOS, Linux, a Chromebook or a phone.

Video remove background jobs are the whole point of this page: you upload a clip and the person comes back separated from everything behind them. To remove video background areas the tool hands back three files for that one upload (a transparent WebM, a green-screen MP4 and an alpha matte), from clips up to 2 GB and 90 seconds. The bg remover video model runs on our own GPU rather than your phone or laptop, so nothing slows down while it works, and your original audio stays in the WebM and the MP4. The output keeps the resolution you sent, up to 1920 px on the longest side.

On the free tier you can remove bg from video files 10 times a day; the count resets at midnight and nobody asks for a card. That makes it a background video remover you can come back to rather than a one-off trial: a video background remove free pass doesn't expire. Because it runs in a browser tab, you can erase background online the same way on Windows, macOS, Linux, a Chromebook or a phone. Deleting background online here is AI segmentation, not a colour key, so a remove bg video job needs no masking from you, and a bg video remover that returns separate files is easier to work with than one flattened export.
- Works in any modern browser: no download
- No sign-up and no watermark on the output
- Runs on our GPU, so your device stays cool
- Same result on desktop, Chromebook or phone
There's no blur step inside the page. If a blurry video background is what you're after rather than a full cut-out, lay the transparent export over a blurred copy of the original in your editor: that is how to blur background in video with this tool, and it also covers a background eraser video job that only softens what's behind you. As a video bg remover it gives you the same files either way, so a remove full video background online free pass and the lighter blur version start from the same download.
Three downloads, ready to use
Every job hands you three files so you're never stuck: a transparent WebM with a real VP9 alpha channel (it plays with transparency in browsers and OBS; Premiere Pro, Final Cut and DaVinci Resolve don't import WebM alpha, so use one of the other two files there), a green-screen MP4 you can chroma-key in any app, and a black-and-white alpha matte MP4 for precise compositing. Your original audio stays in the WebM and the MP4. A short transparent GIF of the first 10 seconds comes along as a bonus, for chat stickers.

For a website or an OBS overlay, reach for the WebM; for a video editor that can't read alpha, use the green-screen MP4 and key it out. The OBS overlay guide shows the streaming setup end to end. All three files keep full HD resolution up to 1920 px, so it also works as an instant background remover for HD clips without shrinking anything.
As a video background changer it only goes as far as transparency or a green screen; a solid colour or a new scene goes in afterwards, in your editor. Nothing installs on your machine: it is a free video background remover online in the plain sense, where you upload from the browser and the AI runs on our GPU. Every video background remover online free run gives the same three files, with no card and no trial period. GPU time isn't free for us, which is why there is a daily allowance, but the export costs you nothing. What comes back from each video clip is a clean video cutout of the subject. If you shot against a green screen, that's fine, but nothing here is keyed out the way a chroma key would do it: the model finds the person in each frame, so a green video background, even one where the background green is patchy or creased, is handled like any other.
A big video background remover, realistically sized
A big video background remover usually means one of two things: a clip that's a big file, or a tool that handles the job well. On file size, 2 GB is genuinely big: most phone clips land nowhere near it. The number that actually limits a "big" upload here is the 90-second cap, not the 2 GB one: a short, heavy 4K clip can hit that time limit while still sitting well under the byte ceiling.
This is an AI background removal tool from start to finish: a segmentation model does the separating, not a manual colour key. You can run several clips in a row, one at a time, to get footage for a whole project. To delete background from video without opening an editor, you do the whole job on this page, and if you were looking up how to edit the background of a video, the four steps below cover it. A change video background online free result costs nothing within the daily allowance of 10 clips, up to 2 GB and 90 seconds each. Footage with a green background already in frame works the same as anything else.
How to do it
The tool is tuned for short clips: up to 2 GB and 90 seconds per upload, processed at up to 1920px. Longer material? Trim it into parts first: that keeps processing fast and free for everyone. A human subject is what it does best.
- Open VideoBGNinja in your browser.
- Upload your clip (MP4, MOV or WebM, up to 2 GB / 90 seconds).
- Wait while the AI removes the background on our GPU.
- Download the transparent WebM, green-screen MP4 or alpha matte.

Common questions
Do I need to install anything?
No. Nothing to install, no account: just upload a clip and download the result. Anyone who wants a bg remover for video free of any install step can use this one from the browser tab: nothing to download, and the AI runs on our own GPU.
Does it work on my phone?
Yes. Any modern browser works, since the heavy lifting happens on our GPU, not your device.
How long can the video be?
Up to 90 seconds and 2 GB per clip. Trim longer footage into parts first.
Is my upload kept?
No. It's deleted right after processing and results are wiped within 45 minutes.
Is this the same as a "background editor online" or "background changer"?
Partly. A background editor online or an online background editor usually lets you swap what's behind the subject. This page does the first half of that for video: it cuts the person out and hands you a transparent WebM or a green-screen MP4. It is not a full online background changer, though. To replace background online with a solid colour or a new scene, drop the transparent file onto that colour or scene in your editor, where a background color change or any background color changer takes a few seconds. So for the cut-out step this is a background editor online free of charge; the background change itself happens in your editor.
Is video background removal really free here, or just a trial?
Really free, and not a one-off trial. You can remove background from video free of charge 10 times a day, each clip up to 2 GB and 90 seconds, exported without watermark and without a card. The count resets at midnight, so you can remove video background free again the next day. The only paid option is a one-time pass (€3 for 24 hours or €5 for 30 days) for longer clips, 4K and ProRes; it doesn't change the quality of the free result.
Does the free background remover video leave it transparent, or just a solid colour?
Actually transparent: the WebM download carries a real alpha channel, not a flat colour painted where the background was. You also get a green-screen MP4 if you'd rather key it yourself.
Is this an AI remove background video free tool, or a manual green-screen trick?
Genuine AI: a person-segmentation model reads each frame and works out what's you and what's behind you. You don't need a green screen or any manual keying; the background remover AI does the separating on our GPU.
Is there a video background remover free download, or does it only run in the browser?
Browser only, by design: the AI runs on our GPU, not your device, so there's nothing to download and install. You just get the finished clip back.
Is there a free HD video background remover that doesn't need a sign-up?
Yes. Exports go up to 1920 px on the longest side, there's no account and nothing is charged. That makes it a fair answer to a free background remover online or free bg remover online search when the file is a video; for photos, BGNinja is the sister tool.
Can I remove background from videos in bulk, or one clip at a time?
One clip at a time per visitor, and you get 10 clips a day, resetting at midnight. There's no batch upload for a folder of videos in one go.
How do I remove background from video, step by step?
Open VideoBGNinja, upload your clip (MP4, MOV or WebM, up to 2 GB / 90 seconds), wait while the AI works frame by frame on our GPU, then download the transparent WebM, green-screen MP4 or alpha matte. That's the whole how to remove background from video (or remove background of video, if that's how you phrase it) process, start to finish: no software and no account needed.
What makes this the best video background remover for a person, specifically?
It's tuned for one job, a human subject, rather than trying to segment anything in frame, and it hands back three usable formats instead of one flattened export. Whether that makes it "the best" depends on your footage; a busy multi-person scene is harder for any segmentation model.
Does it work on objects, pets or products, not just people?
Not reliably. It's built for a human subject. Products, pets and other objects may come back partly or not at all, and a clip with nobody in it can come back almost empty. Use it to remove the background as a whole: it treats everything behind the person as one layer, so it can't pick out one object back there and remove just that.
Is this the same as Cutout.pro's remove background tool?
Different service. Cutout Pro remove background and its remove bg cutout mode are aimed mainly at photos, with video as an add-on; this page is built specifically for video, free, with no account and no per-clip credits to buy.
Is this the same as BigVU's AI video background remover?
Different service. BigVU is a teleprompter and video-recording app for creators, with background removal as one feature inside a larger subscription; this page does only the one job, background removal, free, with no account and no recording features attached.
Can I remove just a black background, a white one or a green screen?
Yes. The AI looks for the person, not a colour, so it doesn't matter what's behind them. You can remove black background from video online, remove white background from video or remove green screen footage the same way, and a green background behind you causes no more trouble than any other. If you want a green background afterwards, take the green-screen MP4. To change the background to a solid colour, lay the transparent WebM over that colour in your editor. One catch: if you want to drop just a black background from a logo animation or a graphic with no person in it, this tool isn't the right fit.
Does this also remove background noise or music, not just the visual background?
No, this tool only touches the picture. To remove background noise from video online (hum, hiss, room noise), use CleanGrab. To remove background music from video while keeping a voice, or to remove vocals from a track and keep the music, StemGrab's stem splitter separates the vocal from the music; that is also the place to remove vocals online from a song. Neither job happens on this page.
Can I remove background on video that was shot handheld, not on a tripod?
Yes: a little camera shake doesn't stop the segmentation model from finding the subject; fast whip-pans or heavy motion blur are the only real problem cases.
Can this replace what my video call app does for a video chat background?
Not for live calls: this tool processes an uploaded clip, not a live camera feed, so a video chat background from your call app's own settings is still the right tool for that job. For a recorded clip, upload it here instead.
What if the person walks in and out of frame?
That mostly works. The model picks the person up again when they come back, though edges right at the frame border are the hardest case for any segmentation model.
Do I have to download all three files?
No. Every job makes all three, but most people take one: the WebM if your software reads transparency, the green-screen MP4 if it doesn't. The alpha matte is for compositing by hand. The point is to remove bg free and without fuss, so pick the file you need and skip the rest.
Is there a video player built into this page?
Only for your own result. It isn't a general online video player, but when processing finishes you can play video online right on the page to check the cut-out before you download. That built-in video player online plays the WebM, the green-screen MP4 and the matte.
Can I merge, resize or loop clips here too?
No. It handles one clip at a time and only changes the background. If you need a video merger online to combine videos online first, to join video online from two parts or to join videos online from several, use the ConvertNinja merge tool linked below and upload the merged file here. The same goes if you need to resize video online: this tool keeps the frame size. To loop video online afterwards you don't need a separate video looper online either; the transparent WebM loops once you load it in OBS as a Media Source with Loop ticked, see our OBS overlay guide.
A few related jobs, and where they actually live
An online video looper isn't needed on top of this either: because the WebM export carries transparency, loading it into OBS as a Media Source with Loop checked repeats it seamlessly as a stream overlay. The compressed green-screen MP4 export would need re-encoding first to loop that cleanly.
Looking for an online video watcher to preview the clip before you download? The result player on this page does that the moment processing finishes. As a video watcher online it only plays back what this tool just produced, not other files on your device; your browser can open those directly, without any upload.

Need it with the background noise gone instead of the background itself: remove noise from video online free? That's a different job: CleanGrab's remove background noise from video takes the same kind of clip, strips hum, hiss and room noise from the audio, and hands back the identical picture with clean sound.
Split video online usually means cutting one section out of a longer clip; ConvertNinja's trim video tool does exactly that: pick a start and end point and download that piece. As a video splitter online it makes one cut per pass, so splitting a clip into two separate files means running it twice, once for each half.
For an online video merger instead, stitching two or more clips into one, rather than pulling a background out of one, ConvertNinja's merge videos tool takes 2 to 10 files and returns one MP4 in the order you picked them.
Need it muted video online rather than background-free? ConvertNinja's remove audio from video strips the sound track entirely and hands back a silent MP4, the picture copied through untouched.
A mute video online pass there needs nothing more than the upload, no timeline or settings, and keeps the file size close to the original, since only the audio track is dropped and the picture isn't re-encoded.
