Remove a Watermark from a Video Online for Free

You can clean a watermark from a short video in the browser without installing anything: upload a clip you own, mark the overlay, let the tool rebuild that area in every frame, and download the result with your audio kept. Free accounts get one clip up to 15 seconds a day.

Only upload content that you own or have permission to modify. Removing watermarks from other people's copyrighted work may violate their rights.

  1. 01

    Upload a short clip

    MP4 or WebM up to 100 MB. Free accounts process clips up to 15 seconds; Premium goes up to 5 minutes and 20 clips a day.

  2. 02

    Mark the overlay

    AI Auto Detect finds a clear corner logo or banner, or you can draw the box yourself. The same area is cleaned in every frame, so static overlays — logos, channel names, date stamps — give the best result.

  3. 03

    Let it process

    The tool walks through the clip frame by frame and rebuilds the marked area from the surrounding pixels, keeping your audio track. Progress is shown as it goes.

  4. 04

    Preview and download

    Play the result, drag the before/after slider, then download. You get MP4 where your browser supports it, otherwise WebM.

What "free" means here

One video clean-up a day up to 15 seconds, plus three image clean-ups. No card, and no watermark added to your output. Premium adds 20 clips a day, clips up to 5 minutes, HD export, priority processing and no ads.

Why some clips are harder than others

Anything that moves leaves the tool less to work with. A mark over fast motion, rain, a crowd or water is rebuilt from a few frames of guesswork and can look soft. Marks over calm backgrounds — sky, a plain wall, an end-card — clean up best.

Keep the original

Processing writes a new file; your upload stays where it is until automatic deletion 24 hours later. Keep your original export somewhere safe, because you may want to re-run with a tighter selection.

Frequently asked questions

Can I remove a watermark from a video online for free?
Yes, within the free plan: one clip a day, up to 15 seconds, in the browser with nothing to install.
Does it keep the sound?
Yes. The audio comes from your original file rather than being re-recorded.
How long does processing take?
Roughly the length of the clip plus a moment to finish writing the file. It runs on your device, so a faster phone or laptop finishes sooner.
Can you remove a moving watermark?
Sometimes, with limits. The tool cleans one fixed area, so a mark that drifts across the frame needs several selections or a manual edit.
Is it legal to remove a watermark from a video?
When the video is yours or you have permission to edit it, yes. If it belongs to someone else, removing their mark and reposting can violate their rights.
