How to remove a video background — free, in 3 steps
UnBG is the fastest way to get a transparent video without a green screen, without paying for Adobe After Effects rotoscoping, and without uploading a single byte to anyone's server. Here's exactly how it works.
1. Upload your video
Drag any MP4, MOV, or WebM up to 3 minutes long onto the dropzone above. The file stays on your computer — there's no upload progress bar because nothing is being uploaded.
2. AI removes the background frame by frame
We use Google's MediaPipe Selfie Segmentation model running directly in WebGL. It detects the subject (a person, a product, a pet) and erases everything else, preserving the original audio track and exact playback speed.
3. Download a transparent WebM
You get back a VP9 + alpha WebM ready to drop into After Effects, Premiere Pro, DaVinci Resolve, Final Cut Pro, or CapCut. The alpha channel is real — composite over any background, gradient, or footage.
What people use UnBG for
Anywhere you'd normally reach for a green screen, chroma keyer, or expensive rotoscoping plugin — UnBG gets you 90% of the way in 30 seconds.
Product demo videos
Isolate your product or hands-on demo and place it on branded backgrounds for landing pages and ads.
Online course instructors
Float a talking-head over slide decks, code editors, or screen recordings — like a built-in picture-in-picture, but cleaner.
Podcast video clips
Pull the host out of their studio and drop them into animated lower-thirds for social cutdowns.
Real estate & e-commerce
Replace messy backgrounds in walkthrough or unboxing videos with neutral or branded backdrops.
Twitch & YouTube streamers
Generate transparent webcam overlays from pre-recorded intros and outros without OBS chroma key fiddling.

Frequently asked questions
Is this video background remover really free?+
Yes — 100% free, no signup, no watermark, no credit card. Ads on the page keep the lights on.
Is my video uploaded anywhere?+
No. The entire pipeline runs in your browser via WebGL and MediaPipe. Your file never touches our servers.
What format is the output?+
A transparent WebM using VP9 + alpha channel, with the original audio preserved at the original speed.
Will the transparent WebM work in CapCut / Premiere / Final Cut?+
Yes. WebM with alpha imports natively into After Effects, Premiere Pro, DaVinci Resolve, Final Cut Pro, and CapCut Desktop. For CapCut Mobile, convert to ProRes 4444 or HEVC with alpha first.
What's the maximum video length?+
3 minutes per clip. For longer videos, split them and process each segment.
Does it work without a green screen?+
Yes — that's the entire point. The AI segments people and subjects from any background automatically.
Why is processing slow on my older laptop?+
Background removal runs on your GPU. Newer machines and Chrome/Edge with hardware acceleration enabled will be dramatically faster.
Can I remove the background from a video with multiple people?+
Yes, the model segments all people in frame. Works best when subjects are reasonably separated from the background.
