Photographers, illustrators, and stock agencies add watermarks to discourage unauthorised reuse and to keep attribution visible when an image circulates. The forms are familiar: a semi-transparent © notice running diagonally across the frame, a studio wordmark in one corner, a full-image tiled pattern that makes the file useless without a licence, or a small signature a creator added to a portfolio shot.
If you legitimately bought or licensed an image, you usually get a clean delivery on checkout. Not always: some services only hand over the marked preview until payment settles, some licences restrict the clean file to specific formats, and archived downloads from services that have since shut down can leave you stuck with marked copies you paid for. This tool is built for those cases — to help you recover a clean version of something you already own.
For images you do not own, you need explicit permission from the creator. Removing a watermark does not transfer copyright. The image remains protected, and stripping the attribution can be treated as a separate violation on top of any unlicensed use — US law calls this Copyright Management Information removal (17 USC §1202), and similar rules exist in the EU and most other jurisdictions.
