How to watermark your photos
Open a photo
Start with one typical picture from the set. It opens in the editor with a sample text mark in the bottom-right corner, ready to change.
Design the mark
Type your text or pick a logo file, then set the size, opacity, corner and distance from the edge. Turn on tiling to repeat it across the whole picture.
Apply to the rest
Save this photo, or choose Apply to many and add the others. Every file gets the same mark, and the batch downloads as one zip.
FEATURES
What this page does
Text or logo
Write a name, a website or a copyright line in a clean sans or a monospace font, or use your own logo, ideally a PNG with a transparent background.
Consistent on every size
The mark is sized and placed relative to each picture, so a portrait phone photo and a wide camera shot get it in the same corner at the same proportion.
Nine positions and a margin
Any corner, the middle of any edge or the center, with a margin that keeps it clear of the border.
Tiled marks
Repeat the mark diagonally across the whole image for proofs and previews, where a single corner mark would be too easy to crop off.
Opacity and shadow
Fade the mark so it doesn’t fight the photo, and add a soft shadow so white text stays readable on a bright sky.
Watermarking a whole folder
Photographers delivering proofs, shops listing products and anyone posting a series of pictures need the same mark on every image. Set it up once on a representative photo, then choose Apply to many. The watermark becomes part of the batch recipe, alongside the format, size and quality, and runs on every file you add.
Because the size and margin are fractions of each photo’s shorter side, the mark looks the same on a tall portrait and a wide panorama, and on a small web copy and a full-size original. The batch summary shows each result before you save the zip, or write the files into a folder in Chrome and Edge.
Where to put a watermark
A small mark in a corner credits you without spoiling the picture, which suits social posts and portfolios. It is also the easiest to crop away. A mark nearer the middle, or a faint tiled pattern over the whole image, protects better and is the usual choice for proofs a client hasn’t paid for yet.
| Goal | Setup |
|---|---|
| Credit on social posts | Bottom-right corner, small, partly transparent, with a shadow |
| Proofs for a client | Tiled across the image, low opacity |
| Product photos for a marketplace | Small logo in a corner, kept clear of the product |
| Screenshots in a tutorial | Website address along the bottom edge |
Using your logo
A logo with a transparent background, saved as PNG or WebP, sits on the photo cleanly. A JPG logo brings its rectangle of background with it. White or single-color versions of a logo usually work better than the full-color one, especially at reduced opacity.
The logo file is read in your browser and kept with your edit while you work; it is not sent anywhere. Pick a version at least as large as the mark will appear on your biggest photo, so it never has to be enlarged.
What a watermark can and can’t do
A visible mark tells people where a picture came from and discourages casual reuse. It does not make copying impossible: a corner mark can be cropped off, and determined people can paint out even a tiled one. Treat it as a credit and a deterrent, and keep your full-resolution originals unmarked and private.
The watermark is painted into the pixels of the saved file, not added as a layer or a note in the metadata, so it survives when the photo is re-shared or re-saved. Metadata such as the camera’s location is still removed from the output by default.
Is it really private?
Photos that need a watermark are usually unpublished work: client shoots, products before launch, artwork. Here they are opened, marked and encoded in your browser, and the originals and your logo never leave your device.
There is no account to create, so there is nowhere a copy of your photos or your logo could be stored.
You don't have to take our word for it. Three checks:
- Open your browser's developer tools, choose the Network tab, then open and save an image. No request carries your file.
- Open an image here once, then turn on airplane mode and run the same job again. It still works, because nothing needs a server.
- Read the page's response headers: its Content-Security-Policy lets it connect only to this site itself, so there is no outside host a file could go to.

Frequently asked questions
How do I add a watermark to many photos at once?
Set up the watermark on one photo, choose Apply to many, then add the rest of the files or the whole folder. Every image gets the same mark, and the results save together as a zip.
Can I use my logo as a watermark?
Yes. Switch the mark from text to logo and pick the image file. A PNG with a transparent background gives the cleanest result.
Will the watermark be the same size on every photo?
The same relative size: it is measured from each photo’s shorter side, so it takes up the same share of a small image and a large one, in the same position.
How do I make a watermark transparent?
Lower the opacity slider until the mark is visible but quiet. Somewhere around half is a common choice for corner marks; tiled marks are usually fainter.
Can someone remove my watermark?
A corner mark can be cropped off, and any mark can be painted out with enough effort. A tiled mark across the whole picture is much harder to remove cleanly, which is why proofs use it.
Is the watermark added to the original file?
No. Your original stays untouched on your device. The watermarked version is a new file you save separately.
