Add a Watermark to a Video

Your logo or mark, your opacity, your position — Free, No Upload, No Forced Branding

A watermark deters reuploads, credits your channel and keeps your brand on screen wherever a clip travels. The irony of most "free" watermark sites is that they stamp their own logo onto your video. This page shows how to add only your watermark to a video, set its transparency and place it precisely — entirely in your browser, with no upload and nothing of ours added.

Add your own transparent PNG or logo to a video, control opacity and position, and export with zero third-party watermark.

What makes a good video watermark

A watermark works best when it's visible enough to identify you but subtle enough not to distract. That balance comes down to four things: the artwork, the opacity, the size and the position. The tool gives you direct control over all four, and a live preview so you can judge the result before exporting.

Use a transparent PNG

The cleanest watermark is a PNG (or WebP) with a transparent background, so only your logo or text shows over the footage and the rest of the frame stays fully visible. Drop it in as the overlay and its alpha channel is respected automatically — no box, no fill, just the mark.

Set the opacity

A solid 100% watermark reads as part of the video; a faint one at 40–60% protects the clip while staying out of the way. Lower opacity is the classic "ghost" watermark used by stock footage and photographers. Pick the level that fits how aggressive you want the protection to be.

Choose size and position

Size is a percentage of the video, so the same setting holds up whether the export is 720p or 4K. A small mark in a bottom corner is discreet and on-brand; a larger, low-opacity mark across the center is much harder for someone to crop or blur out. Use the margin control to keep a corner watermark from touching the very edge, where players sometimes add controls.

Apply it to the whole clip

Leave the timing on Whole video so the watermark stays on every frame from start to finish — protection only works if it's always there. If you instead want a credit that shows only at the start or end, switch to a timed window and set the appear/disappear seconds. Either way, the watermark is re-encoded into the video locally, so the file you download is already protected and nothing was uploaded.

Frequently asked questions

Can I use a text watermark?

Yes — export your text as a transparent PNG first (any image editor does this), then drop it in as the overlay. You get full control over the font and styling that way.

Will the watermark survive re-encoding by social platforms?

Yes. The watermark is burned into the pixels, so it stays visible after TikTok, Instagram or YouTube re-compress the upload. It is part of the image, not a removable layer.

Can I animate the watermark?

If you supply an animated GIF or a WebM with transparency as the overlay, yes — the watermark can move. A static PNG stays fixed.

Is my video uploaded?

No. The video and watermark are processed in your browser and never sent to a server.
