About this tool
A watermark marks a video as yours and discourages reuse. Choose a PNG with a transparent background for the cleanest result, set its size as a percentage of the video width so it scales with the resolution, and adjust the opacity: 70 to 90 percent is visible without dominating the picture.
Drag the logo anywhere on the live preview or tap one of nine positions. You can also limit the watermark to part of the video, for example only the first few seconds.
Why use ToolsCrow for this
- Your logo, not ours. ToolsCrow adds nothing to your video.
- Scales with the video. Size is a percentage of the width.
- Position and timing. Nine presets, free dragging, and a time range.
- Private. The logo and video stay on your device.
Good to know
- One watermark image per pass. The watermark stays in one place; it does not move around the frame.
- A visible watermark can be cropped out by someone determined; it discourages casual reuse rather than preventing theft.
Frequently asked questions
Is my video uploaded to a server?
No. Everything runs inside your browser tab using your own device's video hardware. Your file is never sent to ToolsCrow or anyone else, which also means there is no waiting for an upload and it keeps working if your connection drops after the page has loaded.
Is it really free? Is there a watermark?
It is free with no sign-up, no watermark and no daily limits. The only limits are the ones your device sets: memory and processing power.
How large a video can I use?
Because the video is processed on your device, the limit is your device's memory rather than a server quota. Phone clips of several hundred MB are fine on most devices, and desktop computers usually handle 1 to 2 GB. Files over about 4 GB are not supported.
Which browsers work best?
Current Chrome, Edge and Safari (16.4 or newer, including iPhone and iPad) work best because they include the WebCodecs video engine. Recent Firefox versions work for many files. Older browsers fall back to a much slower real-time mode or may not work at all.
What image format should the logo be?
PNG with a transparent background. JPG works but shows a rectangle behind the logo. Large images are scaled down automatically.
How do I add a text watermark instead?
Use Add Text to Video, set a low opacity look with an outline and place it in a corner.
Why do this in a browser instead of an app?
There is nothing to install, nothing to sign up for and no upload. The work is done by the same video engine your browser uses to play video, so it is fast on any reasonably modern phone or computer, and your file never leaves the device.
