Watermark Image
Protect drafts, proofs and photos with a text watermark you fully control: place it in any corner or center, tile it across the whole image, tune size and opacity — the watermarked copies are generated on your device.
Nothing is uploaded, so you can watermark unreleased work, client proofs and confidential scans without sending them anywhere.
Frequently asked questions
Can someone remove my watermark?
A visible watermark is a deterrent, not encryption — anything visible can be edited out with effort. For real protection, share low-resolution proofs instead.
Does it work with transparent PNGs?
Output is JPG, so transparency is flattened onto white. Watermark the original PNG with a background color of your choice if you need alpha.
