How to remove a watermark from a photo on iPhone or Android
CleanMarks works in Safari and Chrome on phones, so there is nothing to install. Open this page, tap Open photo, and choose the picture. Use a brush size a little bigger than the watermark’s letters: one or two thick strokes erase better than many thin ones. After you download, the image lands in your Downloads or Files app. On iPhone, long-press it and choose Save to Photos.
Which watermarks come off cleanly
- Corner logos and URLs over plain backgrounds: nearly always invisible after one pass.
- Semi-transparent text across the middle: good on texture, so use AI fill where it crosses a face or product edge.
- Dense tiled patterns: slow and imperfect, because every region is covered. Expect to touch up.
Use it on images you have the right to edit
Watermarks exist to protect someone’s work. CleanMarks is built for your own photos: an old logo on your product shots, a date stamp from a film camera, a preview mark on an image you have since licensed, a stranger in your holiday picture. Removing a watermark from someone else’s photo to reuse it can break copyright law (in the US, 17 U.S.C. § 1202 covers removing copyright management information). If you need a stock photo, license it; the clean file comes with the licence.
Questions
How do I remove a watermark from a photo without Photoshop?
Open the photo on this page, brush over the watermark and press Erase. The on-device eraser uses the same patch-based idea as Photoshop’s Content-Aware Fill, and AI fill handles what patches cannot.
Why does the erased area look blurry?
The eraser could not find a matching patch, usually because the mark crosses a unique detail such as an eye or a letter. Undo, mark a smaller area, or use AI fill.
Can I remove a watermark from a screenshot?
Yes. For flat backgrounds and UI screenshots the on-device eraser is usually perfect. Download as PNG to keep text crisp.
