Free Watermark Maker
Watermark Maker adds a text or logo watermark to up to 100 photos at once and saves them at full resolution. Set size, color, opacity and rotation, then place the mark in one of nine positions or tile it across the picture. Sizes scale with each photo's width, and SVG logos stay sharp at any size.

Quick answers
Are my photos uploaded?
No. The watermark is drawn in your browser and the files never leave your device.
Will the watermark look the same on photos of different sizes?
Yes. Size, margin and spacing are measured as a percentage of each picture's width, so the watermark keeps the same proportions on every photo.

Frequently asked questions
Which logo format works best?
A PNG with a transparent background or an SVG. SVG logos stay perfectly sharp at any size.
How do I make the watermark hard to remove?
Use the tiled pattern: the mark repeats diagonally across the whole picture, which is much harder to crop or retouch than a single corner logo.
