Watermark an image
Stamp a photo with text or a logo. Position it on a 3×3 grid or tile it across the whole frame, rotate and scale it, and watch the result update live before you save.
Watermark
Measured in the image's own pixels, not the preview's on-screen size.

Position
Relative size of the logo against the image's shorter side.
Output
This format has no alpha channel, so transparent areas need a solid colour underneath.

Text marks versus logo marks
A text watermark is the fastest way to claim a proof or a preview — "SAMPLE", a name, a copyright line. It's legible at any size and costs nothing to set up. A logo mark takes more preparation but reads as more deliberate, and a PNG with a transparent background blends into the photo instead of sitting on top of it as a block.
Both share the same placement, rotation and opacity controls, so switching between them keeps the position you already chose.
Choosing a position
Corner placements are the least intrusive and the easiest to crop out, which makes them a reasonable choice when the watermark is mostly a courtesy rather than a deterrent. Centre placement is the hardest to remove without damaging the image underneath, but it's also the most visible, which matters for a portfolio proof someone shouldn't be able to screenshot around.
Tile mode repeats the mark in a grid across the entire frame. It's the most resistant to cropping, since removing every instance means removing most of the photo, but it's also the most visually intrusive — reserve it for genuine proofs, not finished delivery images.
Opacity and legibility
A watermark that's fully opaque competes with the photo for attention; one that's too faint stops doing its job. Somewhere between 40% and 70% opacity is the usual range for a mark meant to be seen but not dominate, higher for a deliberately obvious "not for distribution" proof mark.
What happens to the file
The mark is rasterised directly into the image's pixels on a canvas, then the result is re-encoded in your chosen format. That means it can't be peeled off later by anyone who downloads the file, but it also means metadata — EXIF, GPS, colour profile — doesn't survive the trip, the same as every other tool here.
Does the watermark stay editable after I save?
No. It's drawn directly onto the pixels, the same way a rubber stamp works on paper. Keep an unmarked original if you might want to change the watermark later.
Can I use a transparent PNG as my logo mark?
Yes. Transparency in the logo is preserved, and the opacity slider layers on top of that, so a logo that's already partly see-through gets even fainter as you lower it.
Will the watermark end up the right size on differently sized photos?
Position, margin and scale are all calculated from each image's actual pixel dimensions, not the size the preview happens to be shown at, so the same settings reapply sensibly whether the source is 800px or 8000px wide.
What does the Tile option do?
It repeats the mark in a grid across the whole photo instead of placing it once, which makes the watermark much harder to crop out — the usual choice for proofs and preview galleries.
Does watermarking remove EXIF data?
Yes. Like every tool here, the image is decoded, redrawn on a canvas and re-encoded, so EXIF, GPS and colour profile data are dropped from the saved file.
