How to remove a watermark from an image

Results depend far more on the background behind the watermark than on the watermark itself. These steps get the cleanest result the tool can give.

  1. 01

    Load the photo, and crop first if you can

    Drop a JPG, PNG or WebP onto the tool. Images wider than 1,000 px are scaled down to 1,000 px wide for editing, so a 4032 × 3024 phone photo becomes 1000 × 750. If the watermark sits near an edge, cropping it out with the Image Cropper keeps more of your original resolution than painting over it.

  2. 02

    Pick Brush for curves, Rectangle for badges

    Brush mode suits handwritten signatures, thin text and logos with irregular outlines. Rectangle mode suits solid date stamps, corner badges and caption bars, where one drag covers the whole mark.

  3. 03

    Size the brush just wider than the strokes

    The brush runs from 6 to 90 px across. Pick a size slightly wider than the lines of the watermark. A brush much bigger than the mark pulls in colours from further away and leaves a more obvious patch.

  4. 04

    Work in short strokes and undo freely

    Paint a few short strokes rather than one long one, because each dab takes its colour from whatever surrounds it at that moment. Ctrl+Z undoes up to 20 steps, so you can try a stroke, judge it, and step back.

  5. 05

    Download the PNG and check it at full size

    Download saves a lossless PNG. Open it at 100% zoom before you use it. Patches that are invisible in the small preview can show up on a large screen.

How the two modes fill the area

A watermark replaces the pixels underneath it. Those original pixels aren't stored anywhere in the file, so any remover has to guess what should be there. This tool guesses from the colours immediately around the mark.

Brush mode stamps a filled circle as you drag. For each circle it averages the pixels in a 4 px ring just outside the brush and fills the circle with that one colour. Stamps are placed every quarter of the brush width, so a 24 px brush stamps every 6 px, and a 300 px stroke lays down about 51 overlapping circles. Because later stamps sample earlier ones, a long stroke gradually drifts in colour. Short strokes avoid that.

Rectangle modereads the colour just outside each side of your box: left and right edges row by row, top and bottom edges at the middle of the box. It blends them smoothly across the inside and adds a touch of random noise so the patch doesn't look perfectly flat. On a 200 × 60 px date stamp, that fills 12,000 pixels in one go, and gradients come out more naturally than with the brush.

Fine texture (grass, fabric, gravel)Visible blotchesVisible smooth patch
Over a face, text or sharp edgePoorPoor

The last row is the honest limit. If a watermark crosses someone's face, a line of text or a hard edge, no surrounding-colour method can rebuild what was underneath. For those, an AI inpainting model or a clone and healing brush in a desktop editor such as GIMP or Photoshop will do better, or the best fix is to find an unwatermarked original.

What people use it for

Date stamps on old scanned prints

Orange date imprints from film cameras usually sit in a corner over sky or floor. A single Rectangle drag over the digits often clears them in one step.

App badges on your own phone photos

Some camera and editing apps stamp their name on every export. On a clean background, three or four Brush strokes are usually enough.

Labels and arrows in old screenshots

Screenshots with flat interface colours are ideal: the surrounding pixels are one colour, so the fill matches almost exactly.

Placeholder text on product mock-ups

Template images often ship with "Your Logo Here" text. Clearing it on a plain backdrop takes seconds and saves reopening the design file.

Your own watermark on an old upload

If you watermarked a picture years ago and lost the original file, this gets you a usable clean copy for small sizes such as a profile or thumbnail.

Limits worth knowing before you start

  • Output is capped at 1,000 px wide. That's plenty for web posts and thumbnails, but not for printing a large photo.
  • No texture is generated. Fills are smooth colour, so grass, hair, fabric and noise-heavy night shots show a soft patch.
  • Metadata isn't kept. The PNG is drawn fresh from the canvas, so EXIF details such as capture date and GPS location are not carried over.
  • Undo history is 20 steps. Each step stores a full copy of the pixels (about 3 MB for a 1000 × 750 image), so the history is capped to keep memory use reasonable.
  • It handles one image at a time. There's no batch mode for a folder of photos with the same watermark.

Frequently asked questions

Yes. There are no limits, no account and no watermark added to the result.
No. The image is drawn onto an HTML canvas in your browser and edited there. Nothing is sent to a server, which you can confirm by disconnecting from the internet after the page loads.
No, and that's deliberate: it's fast and fully local. Brush mode fills each dab with the average colour of a thin ring just outside it. Rectangle mode blends the colours along the four edges of your box across the inside. Neither invents new texture, so busy backgrounds won't match perfectly.
Editing happens on a copy scaled to at most 1,000 px wide, and that's what gets saved. For full-resolution results on large photos, crop the watermark out instead, or use a desktop editor's healing tool.
Any image your browser can open, which in practice means JPG, PNG and WebP, plus GIF (first frame only). The output is always PNG, so a heavily compressed JPG may come out as a larger file.
Ctrl+Z (Cmd+Z on a Mac) or the Undo button steps back through your last 20 changes. Redo puts them back. Reset returns to the image as you loaded it.
Painting with a finger works, but a fingertip covers a lot of a small screen, so precise strokes are hard. Zoom the page in, use a smaller brush, or switch to Rectangle mode on mobile.
Not well. Large, semi-transparent tiled watermarks run across the subject itself, and filling them with surrounding colour would erase the detail underneath. This tool is built for small, localised marks.
It depends on whose image it is. Removing marks from your own photos, or from images you've licensed with permission to edit, is fine. Stripping a watermark from someone else's copyrighted image to use it without a licence can infringe their rights, and in the US, removing copyright management information is separately restricted under the DMCA.
