100% private — your image never leaves your browser
A watermark is how you put your name on your work before it goes public. Whether it is a photographer protecting proofs, a designer sharing a draft, or a shop guarding product shots, this tool overlays text or a logo directly in your browser — so the images you are protecting are never uploaded to a stranger’s server in the first place.
Add a line of text and dial in the font size, colour, opacity and position, or drop in your own logo image and place it where you like. Turn on tiling to repeat the mark across the whole photo for stronger protection, then export a clean PNG or JPG.
Text watermarks with full control
Type your name, handle or copyright line, then set the size, colour and opacity so it is visible without overwhelming the image. Position it in any corner or the centre, and nudge the opacity down for a subtle mark or up for a bold one.
Logo watermarks
Upload your own logo (a transparent PNG works best), resize it, set its opacity and place it where it reads clearly. Both the source photo and your logo are processed locally — neither is uploaded.
Tile pattern for stronger protection
For proofs and previews you really want to protect, switch on tiling to repeat the watermark diagonally across the entire image. That makes it far harder to crop or clone out than a single corner mark.
Batch watermarking with Pro
Marking one image is free. Pro users can batch-watermark up to 10 images at once with the same settings — a real time-saver for a gallery of proofs or a product line — and it still runs entirely on your device.

Frequently asked questions
Can I add both text and a logo watermark?
Yes. Add a text line with full control over font size, colour, opacity and position, or upload your own logo image — or use whichever suits the photo.
Will a watermark stop people stealing my photos?
It makes casual reuse much harder, especially with the tile option that repeats the mark across the whole image so it cannot simply be cropped off. No watermark is unremovable, but it is a strong deterrent for proofs and previews.
Can I watermark several images at once?
Batch watermarking of up to 10 images with the same settings is a Pro feature. Free users can watermark one image at a time.
Are my photos or logo uploaded anywhere?
No. The photo and your logo are composited locally in your browser with the Canvas API and never leave your device.
