What would you like to do?

Remove the background behind a person → Video background remover, for clips with a clearly visible person.
Remove a green or other solid background → Green screen remover, also suitable for products or pets against a distinct solid backdrop.
Use a photo or solid color as the background → Change video background. The downloaded video includes your new background.
Remove a solid background from an animation → GIF background remover, for animated GIFs with a fairly even background color.

Start in three steps

Choose your file. Open the right tool, select a file from your device and wait for the file check.
Start processing. For people, start with Fast mode. For solid backgrounds, select the background color in the preview. To replace a background, also choose a color or your own image.
Preview and download. Check the edges, movement and sound. Save your result when the download button appears.

To compare details such as hair, try Detailed edges on a short portrait clip. It takes longer, and results depend on the footage. Keep the page open while processing and download before leaving; refreshing or closing clears the task and result.

Before you start

Free allowance: 3 tasks a day as a guest, or 6 in total when signed in, including linked guest use that day. All tools share the allowance, which resets at 00:00 UTC. Downloads have no watermark.
Video requirements: MP4 or WebM, up to 2 GB and 2 minutes, with a total pixel count up to 3840 × 2160. Video output is up to 720p and 30 frames per second, keeping the original proportions.
Download formats: Transparent video downloads as WebM. With a photo or solid background, output is MP4 when supported, otherwise WebM. Before editing, see the import and transparency guide.

Your media is processed on your device and is not uploaded for background removal. First use needs an internet connection to load processing files. Whether processing can finish also depends on your footage and device.

Which browser should I use?

Start with a short clip in current desktop Chrome. Phone support has not been confirmed. If your browser reports that processing is unsupported, try Chrome on a computer.

What are the GIF and background image requirements?

Animated GIFs: Up to 20 MiB, 10 seconds per loop, 2–200 frames and a total pixel count up to 1024 × 1024. Static GIFs are not supported. The output is up to 512 pixels on its longest side; edges may look less smooth than video.
Background images: PNG, JPEG or WebP, up to 10 MiB and 16 million pixels. Images are cropped from the center to fill the video, so choose similar proportions for less cropping.

Common questions

My file will not open or is unsupported. What can I do?

Check that the file plays on your device and meets the requirements above. Renaming a file extension does not convert it. Try exporting a short MP4 from your editor, then opening it in desktop Chrome.

If it still fails, send us the error shown on the page. Multiple audio tracks or sound that your browser cannot read may also prevent processing.

Processing is slow, stuck or failing. What should I try?

First use needs to load processing files. Keep your connection and the page open. For portraits, start with Fast mode. If it still fails, shorten the clip or lower its resolution or frame rate, even if the file is within the size limit.

A full progress bar is followed by a result check; wait for the download button. To stop, select Cancel, then recheck the file to try again. If loading fails, check your connection and whether a browser extension is blocking website resources.

The person is missing or the edges look rough.

Choose a closer, well-lit person with a clear outline. Compare Fast and Detailed edges on a short clip. Hair, fast movement and hidden parts of the subject may still have gaps or flicker.

The portrait tool only identifies people. For products or pets against a distinct solid backdrop, try the green screen remover. Automatic identification of products or pets against complex backgrounds is not supported.

Some background remains, or part of my subject disappears.

Select the actual background color again in the preview, then increase Tolerance a little at a time. Lower it if holes appear in the subject: matching colors in the subject will also be removed. Shadows, reflections and uneven backgrounds can prevent a clean result.

My download has a black background or will not open in my editor.

Some players and editors cannot display transparent WebM correctly. Compare with the website preview, then place the file over a colored background in your editor. A black player background alone does not mean removal failed. Follow the export guide for details.

If you just need a finished video with a new background, combine it in Change video background before downloading.

Will the original sound be kept?

Supported original audio is retained. Silent sources stay silent. If sound cannot be preserved, the tool reports a failure instead of silently creating a muted video. Play the preview to check the sound before downloading. GIFs do not support sound.

Do failures count? What if I use my daily allowance?

Failed or cancelled tasks release their reserved allowance. Retries, switching between Fast and Detailed edges, background changes and repeat downloads within the same task do not count again.

Guests can sign in for 6 tasks in total per day, or wait for the daily reset. Monthly purchasing is not open yet; see pricing for current plans. Remaining tasks from an earlier pack can still be used after the daily free allowance.

Still need help?

Email us with the step that failed, the error message, and your browser and device. A screenshot of the error helps; you do not need to send the full original video. For payment or access issues, include your order reference, not card details.

Where do the examples come from?

Demonstration people and some product clips are AI-generated; GIF examples also include original animations. Results come from the actual tools without manual subject retouching. Try your own footage to judge the result. Each case card links its source; you can also view the portrait sample source and tool sample sources.
