Video Watermark FAQ

Is it free, and is my video uploaded?

It is free with no account, and the video is not uploaded. It is decoded, marked and encoded in your browser, so it never leaves your device. The result carries only your watermark, none of ours.

Which watermark is hardest to remove?

A single mark in a corner is the easiest to crop off. A tiled pattern covers the whole frame, and the moving mark jumps to the opposite side of the picture every few seconds, so cutting one area away never removes it. A partly see-through mark (around 30–60% opacity) stays visible without hiding your content.

Can I use my logo instead of text?

Yes. Add a PNG, JPG, WebP or SVG logo up to 5 MB, on its own or above your text. A PNG with a transparent background looks best. Your last watermark and logo are remembered in this browser for the next video.

Does it lower the quality or remove the sound?

No. The video keeps its resolution and frame rate and is encoded at a bitrate matched to the original, and the sound track is kept. Every frame has to be encoded again to carry the mark, so the file size can differ a little from the original.

Which formats and sizes work?

You can open MP4, MOV, M4V, WebM and MKV videos up to 2 GB and 60 minutes long. The result is an MP4 (H.264 video, AAC sound) that plays almost everywhere; a browser that can’t make MP4 files saves a WebM instead. The file keeps its name with “-watermarked” added.

How long does it take?

A short clip is ready in seconds. Long HD videos take minutes: on a laptop roughly as long as the video plays, longer on a phone. The progress bar shows the time left, and you can cancel at any moment.
