A corner watermark is a crop away from gone

Corner watermarks exist to be attributed, not to be enforced. Anyone who wants your image without your name simply crops the corner off, and the crop usually improves the composition. That is fine when the goal is to make honest reuse easy to credit.

Tiling is the version that actually resists removal, because there is no crop that leaves a usable image and no watermark. It is also, by design, ugly — you are trading the viewing experience for control. Photographers use tiled watermarks on client proofs and corner watermarks on portfolio pieces, and that split is the right instinct.

Whichever you pick, the watermark here is composited into the pixels. Unlike a PDF watermark, it cannot be selected and deleted, only painted over or cropped away.

How it works

  1. Drop in an image
  2. Type your watermark text and set size, opacity and position
  3. Tick Tile to repeat it across the image, then save

Frequently asked questions

Should I tile the watermark or put it in a corner?
Corner for attribution on work you want shared. Tiled for proofs and previews you want to be unusable without payment. Tiling resists cropping; a corner does not.
Can the watermark be removed?
It is composited into the pixels, so it cannot be deleted as an object. It can be cropped off (if in a corner) or painted over by someone patient. No watermark is technically unremovable.
What opacity works best?
Around 30–45% for a corner mark, 15–25% for a tiled one where the repetition makes it visible regardless. Above 60% it competes with the photograph.
Why is the watermark saved as PNG?
Because PNG is lossless, so the sharp edges of text stay crisp. Convert to JPEG afterwards with Compress Image if file size matters more.
Can I use my logo instead of text?
This tool stamps text only. Image watermarking requires positioning and scaling controls that make the interface substantially more complex for a use case most people do not have.
