Watermark image

Stamp your name, © notice or logo on photos before you post them. Put it in a corner, in the middle, or tile it diagonally across the whole image so it can't be cropped off. Watermark many images at once and download them as a ZIP. Free, and your files never leave your browser.

Which watermark style should I use?

A small corner mark (bottom right, 40-60% opacity) credits you without spoiling the picture, which suits portfolios and social posts, but anyone can crop it off. A tiled diagonal pattern at 15-30% opacity covers the whole image, so it survives cropping and is much harder to remove; use it for proofs you send to clients before they pay, product photos that get copied, and ID or document scans you share with a company (write who it is for and the date, like "For ACME rental only, 20 Oct 2026").

How it works

Each image is decoded by your browser and redrawn on a canvas at full resolution, then the text or logo is painted on top with the opacity, angle and shadow you chose. Size and margin are a percentage of the image width, so a batch of mixed photos all get a watermark of the same relative size. Tiled mode repeats the mark in a staggered grid over the whole picture (margin sets the gap). Nothing is uploaded, so it works for private photos and ID scans, and even offline once the page has loaded. EXIF metadata (camera, GPS location) is removed.

Watermarking a PDF instead? Use watermark PDF. Also see add logo to image, blur image to hide details first, or resize image.

Watermark screenshots automatically

Making branded website screenshots for reports or listings? The Shotmint API renders any URL in Chromium, and the same call can render your own HTML, so a logo or a "Captured 20 Oct 2026" label can be part of the image from the start, with no editing step:

curl -X POST https://shotmint.creasework.com/v1/screenshot -H "X-API-Key: YOUR_KEY" -H "Content-Type: application/json" \
  -d '{"url":"https://example.com","width":1280,"height":800}' -o shot.png

Each screenshot is 1 credit. €5 buys 2,000 with no subscription, and credits never expire.

FAQ

Are my images uploaded? No. Everything runs in JavaScript on this page, which matters for ID cards, contracts and unreleased photos.

Can a watermark be removed? A small corner mark can be cropped or painted out in minutes. A tiled, semi-transparent mark across the whole image is much harder to remove cleanly, which is why it is the default here. No visible watermark is impossible to remove, so for valuable work also share only reduced-size copies.

Does it lose quality? The photo keeps its full resolution. PNG output is lossless; JPG and WebP are re-encoded at the quality you pick (High is visually identical for photos).

Is there a limit? No file count limit and no Shotmint mark of our own. Images up to 16,384 pixels per side. Animated GIF and WebP files are watermarked as their first frame.
