Private, local image cleanup

Watermark Remover

Mark the watermark, repair the area in your browser, then preview and download.

Drop an image here or choose a file PNG, JPG, JPEG, WebP, or HEIC

Processing stays in this browser. Your image is not uploaded.

How it works

A transparent, local repair—not a hidden AI claim.

01

You choose the area

Use a brush or rectangle to mask the visible watermark. Nothing is automatically guessed.

02

Canvas rebuilds from edges

The script interpolates clean pixels from opposing sides, then fills unresolved areas inward and applies one light masked-area smoothing pass. No remote model or API is used.

03

The format is checked

PNG stays PNG, JPG/JPEG stays JPG/JPEG, and WebP stays WebP. A download is enabled only when the browser can encode the original format.

Know before you upload

Best for small marks on predictable backgrounds.

This browser-only method works best when nearby pixels provide a believable replacement.

✓ Good candidates

  • Small corner logos
  • Date stamps and short text
  • Marks over sky, walls, fabric, or soft gradients
  • Thin overlays with clean pixels nearby

× Likely to look imperfect

  • Large or full-image watermarks
  • Marks covering faces, hands, or detailed objects
  • Dense patterns with no clean source pixels nearby
  • Watermarks hiding information that does not exist elsewhere

FAQ

Watermark remover questions, answered plainly.

Is this a free watermark remover?

Yes. It runs as a static page with no account, subscription, or server request.

Can I remove a watermark from a photo without uploading it?

Yes. Image decoding, masking, repair, preview, and export happen inside your browser tab.

Is this an AI watermark remover?

No. This version uses a deterministic Canvas-based interpolation algorithm. It does not download or call an AI model.

Can it remove a watermark from any image?

No. Results depend on the background around the mark. Small marks over simple areas are the strongest use case; missing faces or complex objects cannot be reconstructed reliably by this algorithm.

Will the downloaded image keep its original format?

Yes for PNG, JPG/JPEG, and WebP in modern browsers. HEIC is available only when the browser can both decode and encode HEIC; unsupported browsers show an error instead of producing a mislabeled file.
