Text or a small logo on the photo
Stamp the text you type, or a PNG/JPEG/WebP logo under 24 KB. Pick a corner, opacity, and optional repeat. HEIC is saved as JPEG.
A logo replaces the text stamp. Compress or convert on Compress image if you also need a smaller file.
How to watermark
- Drop photos. JPG, PNG, WebP, HEIC, or AVIF.
- Type text, or pick a small logo. Set corner and opacity.
- Process. Download the marked files, or a ZIP.
- Delete when you have the files.
What this will not do
No invisible SynthID. No C2PA signing. Metadata is not a proof of origin.
A 20 MB logo will not load. Keep the mark small. Repeat it if you want it harder to crop out.
This is not an EU AI Act certificate. The 'AI generated' option is a visible label, nothing more. Providers must mark at generation. Read the Commission page for the law.
Questions
Can I use my own logo?
Yes. A PNG, JPEG, or WebP under 24 KB. It replaces the text stamp.
Can I watermark HEIC?
Decoded, then saved as JPEG with the stamp. Same libheif path as HEIC to JPG.
Can I watermark several photos at once?
Up to 10, same mark on each, 20 MB each.
Can I remove a watermark?
No. We only add one.
Which fonts?
DejaVu on the server. Fancy typefaces are out.
How long do you keep the files?
Originals and marked files are deleted within 1 hour, or immediately if you press delete now.
