Remove Watermark

Remove watermarks, logos, dates, and stamps from images using smart inpainting, or add custom watermarks.

Runs in your browser. Nothing you add is uploaded.

What the Remove Watermark does

Removing a watermark from an image means reconstructing what was underneath it, and that information is genuinely gone — no tool can recover pixels the file never stored. What this eraser does is inpainting: you brush over the watermark and the surrounding pixels are blended inward to fill the gap. Over an even background such as sky, a wall, or paper the result is usually indistinguishable. Over busy detail it will look smudged, because there is nothing else to rebuild from. Everything runs on a canvas in your browser, so the image is never uploaded.

How to remove a watermark from an image

  1. Upload the image you own or have permission to edit.
  2. Set a brush size a little larger than the thickness of the watermark strokes — big enough to cover it, small enough not to eat surrounding detail.
  3. Brush over the watermark. Each pass blends in colours sampled from just outside the brush, so short strokes over an even background work better than one large sweep.
  4. Use Undo to step back a stroke, or Reset to return to the original image if a pass goes wrong.
  5. Download the cleaned image as a PNG.

The Remove Watermark runs entirely in your browser — nothing you enter is uploaded, stored, or logged.

When to use it

Erasing a camera timestamp

Date stamps burned into the corner of an old photograph usually sit over sky, grass, or a plain surface, which is the ideal case for inpainting — the fill has consistent surrounding colour to draw from.

Cleaning up your own exported images

Trial versions of design software stamp their output. If you have since licensed the software, removing the stamp from your own past exports saves regenerating them.

Removing a stray object or blemish

The same brush works for anything small and unwanted — a power line against sky, a mark on a scanned document, a spot on a wall.

Good to know

  • Work in short strokes rather than one long drag. Each dab samples fresh surrounding colour, so several small passes blend better than one big one.
  • Match the brush to the watermark. A brush much larger than the mark destroys detail around it that did not need replacing.
  • Inpainting cannot invent texture. Over a face, patterned fabric, or dense foliage the filled area will read as a smudge no matter how carefully you brush.
  • Zoom your browser in before working on a small watermark — the brush maps to image pixels, so a larger view gives finer control.
  • Only remove watermarks from images you own or are licensed to modify.

Frequently asked questions

How does the watermark eraser work?

Select the watermark area with your mouse; the inpainting algorithm blends surrounding textures to fill the area seamlessly.

Is it legal to remove a watermark?

It depends entirely on the image. Removing a timestamp from your own photograph, or a trial-software stamp from output you have since licensed, is ordinary editing. Removing a photographer's or stock library's watermark in order to use or publish their work is copyright infringement, and in many jurisdictions stripping rights-management information is a separate offence on top of it. Use this on images you own or have permission to modify.

Why does the erased area look blurry or smudged?

Because inpainting reconstructs from surrounding pixels, and that is all the information available. Over an even background the reconstruction is convincing. Over detailed texture — hair, foliage, patterned fabric — there is no way to infer what the watermark covered, so the fill reads as a smooth patch. This is a limit of the technique, not a setting you can turn up.

Can it remove a watermark covering the whole image?

Not usefully. Large diagonal watermarks spanning the full frame overlap too much varied content, so brushing them out replaces most of the picture with blended colour. Tools claiming to do this cleanly are generating plausible content rather than recovering the original.

Is my image uploaded to a server?

No. The image is drawn to a canvas in your browser and every edit happens there. Nothing is transmitted, and the cleaned PNG is written straight to your downloads folder.

Does it work on a phone or tablet?

Yes. The brush uses pointer events, so touch and stylus input work the same as a mouse, and the page will not scroll while you are brushing on the canvas.

Why is the download a PNG when I uploaded a JPEG?

PNG is lossless, so the edit is saved without adding a fresh round of JPEG compression artefacts on top of the ones already there. If you need a smaller file, run the result through an image compressor afterwards.
