Image watermark remover

Remove a watermark, logo or date stamp from a photo you own or have the right to edit. Paint over the mark, repair it locally in your browser — nothing is uploaded.

About this tool

This tool repairs a small, marked area of a photo — a watermark, logo, date stamp or an unwanted object — by rebuilding that area from the pixels around it. The repair runs entirely in your browser with the OpenCV inpainting algorithm (Telea), the same family of technique photo editors call content-aware fill. Your image is never uploaded, and the page states plainly which repair engine actually ran.

Inpainting is reconstruction, not recovery: it invents plausible pixels from the surroundings. That is why plain skies, walls, water, sand and soft gradients come out clean, while a mark crossing a face, lettering or detailed texture will look soft or smeared. It is a tool for images you own or have the right to edit — your own product photos with an old shop logo, your own scans with a date stamp — not for stripping a creator’s mark from their work.

How to use Image watermark remover

  1. Choose an image you own or have the right to edit (JPG, PNG, WebP or BMP, up to 20 MB and 24 megapixels).
  2. Paint over the whole watermark with the brush — cover it completely with a small margin, and adjust the brush size to the mark.
  3. Run Remove, compare the original and the repair side by side, then download PNG (lossless) or JPG.

Keep the original files and inspect the exported result before publishing or sharing it.

Frequently asked questions

What kinds of marks can this remove?

Logos, text watermarks, date stamps and small unwanted objects. The repair blends the painted area from its surroundings, so it works best on plain skies, walls, water and other simple backgrounds.

Will it work on detailed backgrounds?

Only partially. Busy textures, faces and sharp edges crossing the mark cannot be reconstructed convincingly by inpainting — the result will look soft or smeared there. The tool tells you this up front rather than promising magic.

Are my images uploaded?

No. The image is decoded, painted on and repaired entirely in this browser tab. The repair library downloads once as a program file; your picture never leaves the device.

Which repair engine is used?

OpenCV inpainting (Telea algorithm) when the library loads. If it cannot load, the page falls back to a built-in diffusion fill and the status line tells you which engine actually ran.

Should I remove watermarks from images I found online?

Only edit images you own or have the right to edit. Removing a creator’s watermark from someone else’s work to reuse it is not a legitimate use.

What are the limits?

One image at a time, up to 20 MB and 24 megapixels. Very large painted areas take longer and repair less convincingly than small ones.
