Add a Watermark to Photos
Watermark a whole batch of JPGs with a text credit or your own logo. Place it in any corner, centre it, or tile it diagonally across the frame for client proofs. Size is set as a percentage of the image, so one setting works across photos of different dimensions, and text gets a subtle shadow so it stays legible over both bright skies and dark shadows. Your photos and your logo never leave the browser.

How to watermark your photos
- Drop in the photos you are publishing — not your only copies.
- Type your credit, or switch to Logo image and pick a transparent PNG.
- Set the size as a percentage: 4–6% is a discreet corner credit, 10%+ is prominent.
- Choose a corner, or tick Tile and set a rotation of about −30° for a proof pattern.
- Drop the opacity to taste and click Add watermark.
Two different jobs, two different settings
Attribution — a small mark, bottom-right, 40% opacity, so your name travels with the image without competing with it. Protection of unpaid work — tiled, rotated, 20% opacity, unavoidable: a client can see exactly what they are buying and cannot use it until they have. Photographers and designers generally need both presets at different moments, which is why size, position, tiling, and opacity are all separate controls here rather than one "watermark" button.
Before you publish
A watermark is visible metadata. The invisible kind travels too: your photos probably carry the camera model, the date, and often the GPS coordinates of where the shot was taken. Watermarking through the canvas drops all of it as a side effect, but if you are publishing files you are not watermarking, run them through Remove EXIF first — it strips metadata at the byte level and leaves the pixels bit-for-bit identical. EXIF viewer shows what a file is carrying before you decide.
FAQ
Can I use my own logo?
Yes. Switch the type to "Logo image" and choose a file — a PNG with a transparent background gives the best result, because the transparent areas let the photo show through. The logo is scaled relative to the photo width, so the same setting works across a batch of different sizes.
Positioned or tiled?
A single mark in a corner is what you want for attribution and looks professional. Tiling — repeated diagonally across the whole frame — is for proofs and previews you are handing to a client before payment: it is genuinely hard to remove without destroying the image, which is the point.
What opacity should I use?
Around 35–50% for a visible corner credit; 15–25% for tiling, where the repetition makes even a faint mark clear. A watermark at 100% opacity mostly signals that no one thought about it. Text keeps a subtle drop shadow by default so it stays readable over both light and dark areas.
Does watermarking stop people stealing my photos?
It raises the cost and it makes casual re-use awkward — nothing more. A determined person can crop a corner mark off or paint it out, and modern inpainting tools are good at it. Tiling across the image is far harder to defeat. Treat a watermark as attribution and friction, not protection, and keep your unwatermarked originals somewhere safe.
Will it re-compress my photo?
It has to — pixels are being changed, so the file is re-encoded. Keep quality at 0.92 or above and the loss is invisible. Watermark the copy you are publishing, never your only original.
