How it works
Add your photos
Choose the images you want to label with your name or copyright notice.
Enter your watermark
Type your own text, then adjust its size, opacity and position.
Save the marked copies
Inspect the watermark in the preview before downloading the labelled images.
Protect and label your photos
A watermark shows who took a photo and makes it harder to reuse without permission. Use a small mark in a corner for portfolios, or a repeated pattern across the whole image for previews and proofs.
Choose white text for dark photos and black text for light ones. An opacity of 40–60% is visible but not distracting.
Why do it on your device?
Photos you want to protect are exactly the ones you should not upload to unknown websites. Here the watermark is drawn by your own browser, and the result is saved on your device. The new files contain no hidden location data.
Questions
Are my files uploaded?
No. The tool runs inside your browser, so your photos are opened and processed on your own device. They are never sent to us or to anyone else.
Can I watermark many photos at once?
Yes, up to 50 with the same settings.
Can I use my logo as a watermark?
Not yet; this tool adds text. Image watermarks are planned.
Which characters can I use?
Any text your device can show, including © and accented letters.
Is it free?
Yes. Free to use, with no sign-up, no watermark and no daily limits.
