Quick answers to common questions
Auto-detect uses classical image heuristics (residual-after-blur, border preference — not AI) to find likely watermarks, then Telea content-aware fill blends surrounding pixels into that region. You can also paint or select the area manually. This is not neural object removal — results are best on simple or near-uniform backgrounds.
Yes. Use Auto-detect & remove for a one-click pass, or Detect only to preview the proposed mask before filling. Detection is heuristic and may miss complex mid-image watermarks — brush, rectangle, and lasso remain available when auto-detect fails.
Only use this on images you own or have permission to edit. Removing watermarks from copyrighted or licensed content you do not own may violate copyright law. Technically, results are best for logos, timestamps, and text on simple backgrounds; busy textures often look imperfect.
No. All processing — including detection and fill — runs entirely in your browser. Your image never leaves your device.
Yes. Undo and redo cover mask painting, detection, and each fill operation (Ctrl/Cmd+Z and Ctrl/Cmd+Shift+Z). You can also clear the mask and start over.

Auto-detect uses classical heuristics (not AI) to find corner logos, timestamps, and semi-transparent overlays, then fills with Telea content-aware inpainting. Complex mid-image watermarks may need the brush. Busy textures can look imperfect.
