If detection grabs the wrong things, choose Pick mark and click one letter of the watermark.

Remove

Patch from the photoPaint over the bad spot and press Remove. Clearmark finds the best matching clean area in your photo and patches from it, keeping real detail. To choose the area yourself, use Copy from and click it. No AI. Symmetry fillFor round objects like watch dials, wheels and plates. Rebuilds hidden parts by copying the matching part from elsewhere on the same object, so markers and patterns come back sharp. No AI. The center is found automatically; use Set center if it is off. AI fillRedraws the masked area with an AI model that runs in your browser. Best quality. Downloads about 110 MB the first time, then takes roughly 20–30 seconds per 512 px area. AutomaticUnblends see-through marks and rebuilds solid ones. Texture rebuildRebuilds the area from nearby patterns. Best for most photos. Unblend overlayReverses a see-through mark and keeps the detail under it. Smooth fillBlends surrounding colors in. Fast, but blurs any detail under the mask.

Unblend strength100%

If a faint ghost of the mark stays, undo, raise this and remove again. Lower it if the area turns lighter or darker than its surroundings.

Review & save

Compare with original

Cleaned spots can look smoother than the photo around them. Restore detail adds back fine grain and texture copied from nearby. Undo if you prefer it without.

Use Clearmark on images you own or have permission to edit. Large images are edited at 3200 px on the long side; Save PNG keeps every untouched pixel at the original resolution.
