Choose imageAbout the Watermark Image
Protect your photos before sharing them: type your name, brand or copyright line and place it anywhere on the image — nine anchor positions from top-left to bottom-right, or a tiled diagonal pattern that repeats across the entire frame for maximum protection. Size, colour and opacity sliders let you balance visibility against subtlety, with the preview updating on every change.
Photographers watermark portfolio shots, sellers mark product photos before listing them, and agencies stamp drafts as proofs — all without wanting those originals on some random server. This tool keeps them off one: watermarking happens on a canvas in your browser, the file is never uploaded, and the marked PNG downloads at the original resolution. Free, no sign-up, no limit on how many photos you process.

Frequently asked questions
What's the best watermark position to prevent theft?
A single corner mark is easy to crop out, so for images you really want to protect, use the Tiled option — it repeats your text diagonally across the whole photo, making removal impractical. For portfolio images where aesthetics matter more, a semi-transparent bottom-right mark is the usual compromise.
Can I add a logo image instead of text?
This tool is text-only: it stamps any words you type, in your choice of size, colour and opacity. For most uses a styled name or brand line works well. If you need a graphic logo overlay, you can composite it separately in the Tooldoodle image editor or a layout tool.
What opacity should a watermark have?
Around 30–50% is the sweet spot for most photos: clearly legible without dominating the subject of the image. Go lighter (10–20%) for subtle branding on portfolio work, and heavier (60% and up) or fully tiled for client proofs and previews that shouldn't be reused before payment. The live preview makes it easy to compare.
Does watermarking lower the photo's quality?
No. The image is exported as a lossless PNG at its original pixel dimensions, so nothing outside the watermark itself changes. Bear in mind the mark is permanently rendered into the pixels — keep your unmarked original, because the watermark can't be removed afterwards.
Are my photos uploaded while being watermarked?
Never. The watermark is drawn over your image on a canvas inside your own browser, and the download is generated on your device. That's precisely the point for many users: you can protect unpublished work without first handing it to a third-party server.
