How to remove a watermark from a video
-
Add your video
Drag your video (MP4, MOV, WebM…) into the box, or pick it from your phone or computer.
-
Box the logo
A box appears in the top-right corner: move it over the logo and resize it with the blue handle, or draw a rectangle with your finger. The corner buttons add a box in one tap.
-
Check and download
Choose Erase, Blur or Pixelate, look at the frame preview, then export: the MP4 keeps the original sound and quality.
A simple, honest logo remover
Three ways to make it disappear
“Erase” rebuilds the area from the surrounding pixels, ideal for a small logo on a plain background. “Blur” and “Pixelate” openly hide a caption, a date or a name.
Several areas, at the right time
Box a logo at the top and a date at the bottom in one go, for the whole video or only between two moments set to the second.
Preview before exporting
One button renders the current frame with the effect applied: you see the real result before processing the whole video.
Nothing is uploaded
Processing is done by FFmpeg right in your browser. No server, no file limit, and no Chatzam watermark on the result.
Erasing a logo, date stamp or burned-in text: how it works
A burned-in watermark is part of the picture itself: no tool can recover what was behind it. The “Erase” method therefore replaces the area with a gradient calculated from the pixels around it (FFmpeg's delogo filter). On a small channel logo, a camcorder date stamp or a number sitting over sky, a wall or a road, the result is very discreet: at most you see a faint soft patch. On a large caption in the middle of a very detailed scene, a trace stays visible: in that case use “Blur” or “Pixelate”, which hide the area openly, or crop the video so the logo falls outside the frame. Tip: draw the box tightly around the logo with a margin of a few pixels, then use the preview button at several points in the video.
Which watermarks are you allowed to remove?
This tool is meant for cleaning up your own videos: the logo of your old channel, the date stamped by a camcorder or dashcam, the name of a trial video editor on your own edit, a caption you added and regretted, or personal information visible on screen. A watermark placed by a creator, a TV channel or a stock footage site protects their work: removing it to reuse the video without permission may infringe copyright. So Chatzam does not promise to “remove the watermark from a movie or from someone else's video”. If it's your own video posted on social media, the cleanest option is to start again from the original still in your camera roll or drafts, which has no watermark.
Moving logo, corner logo: the right approach
The tool's boxes stay in place. If the logo moves during the video, add one box for each position, or process the video in several passes: a first box from 0 to 10 s, export, then a second box on the new video. For a logo tucked in a corner, another option gives a perfect result: slightly crop the video with “Crop Video”, at the cost of a small zoom. If you need to hide a face or a license plate rather than a logo, “Blur Video” is made for that, and for a single photo, “Remove Objects From Photos” removes an unwanted element with AI.
Quality, formats and processing time
The tool reads MP4, MOV, WebM, MKV and most phone formats, and produces an MP4 (H.264 and AAC) that plays everywhere, original sound included. The video is re-encoded at high quality: the difference from the original can't be seen with the naked eye. Processing happens on your device: expect a few seconds for a short clip to a few minutes for a long Full HD video, and a computer is faster than a phone. On first use, the video engine (about 30 MB) is downloaded once, then cached by your browser.
Frequently Asked Questions
How do I remove a logo from a video for free?
Add the video, place the box over the logo, choose “Erase”, check the preview, then click “Remove logo”. You download an MP4 without the logo, with sound, no sign-up and no added watermark.
Does the watermark disappear completely?
It disappears, but the image behind it can't be recovered: the area is rebuilt from the neighboring pixels. On a plain background it's almost invisible; on a very detailed background a faint patch remains. Blurring or cropping are good alternatives then.
Can I remove the TikTok watermark or the one on a movie?
Only if the video is yours and you have the right to reuse it. Removing the watermark from someone else's work to repost it may infringe copyright. For your own TikToks, start from the original without a watermark saved in your camera roll instead.
How do I remove a date stamp from a camcorder or dashcam video?
Box the date (often at the bottom right) with the matching corner button, choose “Erase” or “Blur”, then export. Several areas can be handled at once, for example the date and the time.
The logo only shows up at the end of my video: what do I do?
Choose “Between two moments”, move the video to where the logo starts and tap “Start = current time”, then do the same for the end. The effect only applies to that part.
Is my video uploaded to a server?
No. All processing is done in your browser by FFmpeg (WebAssembly): the video never leaves your device. The tool is free, with no limit on the number of videos.
