Common questions

Are my photos or my logo uploaded?

No. The photos and the logo are opened, marked and saved by your browser on your own device. They are never sent to us or to anyone else, and nothing is stored.

How do I watermark many photos at once?

Choose them all together, or press Add more. The same mark, at the same share of the width, goes on every image. Press Show on any row to preview that image, then Download all (ZIP) for the whole batch.

Should I use a corner or repeat the mark?

A corner mark is discreet and fine for social posts and portfolios, but easy to crop off. Repeat across the picture at a low opacity when the photo must not be reused, for example previews sent to a client before payment.

Why is the size a percentage?

So the mark looks the same on every photo in a batch. A 2,000 pixel phone photo and a 6,000 pixel camera file get a mark that covers the same share of the picture, rather than a fixed 200 pixels that vanishes on the large one.

My logo has a white box around it. Why?

The logo file has a white background rather than a transparent one. Export it as a PNG or SVG with transparency and choose it again, or lower the opacity so the box fades into the picture.

Does it lower the picture quality?

The pixels are copied as they are and the mark is drawn on top. Saving as JPG or WebP re-encodes the picture, which at the default quality of 92 is not visible; choose PNG when nothing may change.

Can a watermark be removed?

A visible mark can be painted over by someone who tries hard enough, and a small corner mark can simply be cropped off. Repeating the mark across the picture makes that far more work. No visible watermark is impossible to remove.

Can I add a watermark to a PDF?

Use Add Watermark to PDF, which puts text on every page without redrawing them.

Is it free?

Yes, completely free, with no sign-up and no limit, and we add no mark of our own.

Nothing happens when I pick a file

The tool runs entirely in your browser, so a very old browser can fail silently. Try the current Chrome, Edge, Firefox or Safari. Your files are never uploaded anywhere.
