Drop a photo above, then stamp it with a line of text (a copyright notice, your name, a handle) or an uploaded logo — PNG logos with transparency layer cleanly over the image. Pick one of nine positions, or dial in size, opacity, rotation, and margin until it sits exactly where you want. Watermarking your work before posting it makes casual reuse traceable and attribution automatic wherever the image travels.
For images that really shouldn't be reused, switch on tile mode: the mark repeats across the whole frame on a staggered diagonal grid, so it can't be cropped out or cloned away without wrecking the photo. A low opacity keeps a tiled watermark readable without burying the image underneath it.
Everything happens on your device — the photo and logo are never uploaded to a server. Before publishing, you may also want to strip location data with the EXIF remover, scale the image down with the image resizer, or shrink the file with the image compressor.
Frequently asked questions
How do I stop people from cropping the watermark out?
Use tile mode. A single mark in a corner is trivial to crop away, but tiling repeats the mark across the whole frame on a staggered diagonal grid, so there is no clean region left to crop to. Removing a tiled watermark means retouching every repetition, which wrecks the photo in the process.
What opacity should a watermark be?
Around 25–40% works for most photos: clearly visible on close inspection without burying the image underneath it. Go toward the lower end for tiled watermarks, since the repetition does the work, and higher if the mark sits over busy detail where a faint mark disappears. The opacity slider here goes from 5% to 100%, so you can dial it in against the live preview.
Can I use my own logo as the watermark?
Yes — switch to Logo mode and upload an image. A PNG with a transparent background works best because it layers cleanly over the photo; JPG, WebP, and iPhone HEIC files are also accepted. The same size, opacity, rotation, and tiling controls apply to the logo as to text.
Does a watermark actually prevent image theft?
Honestly, no — it deters casual reuse and keeps attribution attached as the image travels, but a determined person can clone out a corner mark or retouch even a tiled one with enough effort. Think of it as making misuse inconvenient and provable rather than impossible. For images that must not leak at all, the only safe option is not publishing them.
