Watermark Photos
Put your name or logo on a set of photos in one go. Choose where it sits, how big and how see-through, or tile it across the whole picture, and see it live before you save.
Drop photos to watermark them
JPG, PNG, WebP, AVIF, or HEIC where your browser opens it. As many as you like.
Your photos are processed on this device and never uploaded. The new files carry no location or camera details.

A watermark that protects without spoiling the photo
A corner mark, a name or logo at 50 to 70 percent opacity, credits the photo without getting in the way, and suits portfolios and social posts. It is also the easiest kind to crop off. A tiled mark repeats across the whole picture at an angle; it is much harder to remove, which suits proofs you send a client before they pay, at the price of a busier picture.
Sizes are a share of each photo’s shorter side, so one setting looks the same on a 6000-pixel camera photo and a 1080-pixel phone picture in the same batch. The preview is drawn from the same layout the saved files use, so what you see on the first photo is what every photo gets.
Light text gets a soft dark shadow and dark text a light one, so the mark stays readable on bright sky and deep shade alike. Turn the shadow off for a flatter look on plain backgrounds.
For a logo, a PNG with a transparent background works best; a JPEG logo brings its white box with it. The logo is drawn at the size you choose, and like your photos it never leaves this device.
Photos keep their format and their names, and JPEGs are saved at high quality. The new files carry no metadata, so the watermarked copies don’t carry your GPS location along with your name.
Good to know
- In the United States a photo is protected by copyright from the moment it is taken; a watermark isn’t needed for protection, but it tells people whose work it is. Source: U.S. Copyright Office, Circular 1: Copyright Basics
- US law forbids removing or altering copyright management information, which includes a name or notice in a watermark, to hide an infringement. Source: 17 U.S.C. § 1202, integrity of copyright management information
- PNG supports an alpha channel, so a logo saved as PNG can have a see-through background that lets the photo show around it. Source: W3C: Portable Network Graphics (PNG) Specification
How to watermark photos3 steps, all on your device
- Write your mark. Type your name, studio or a © line, and pick a font and colour. Or switch to Logo and choose an image, ideally a PNG with a transparent background.
- Place it. Tap one of nine positions, or Tile to repeat it across the photo at an angle. Set its size and opacity; the preview shows the first photo exactly as it will be saved.
- Add photos and save. Drop in the whole set. Each photo is marked as it arrives; save them one by one or all at once as a ZIP.
Frequently Asked Questions
Text or logo: which watermark is better?
Text is quickest and always crisp: your name, studio or a © line. A logo looks more professional if you have one as a PNG with a transparent background. Both can sit in a corner or be tiled across the photo.
Will a watermark stop people copying my photos?
Not entirely. A corner mark can be cropped off and a tiled one painted over with effort. It credits you, discourages casual reuse and makes removal deliberate; in the US, removing it to hide an infringement is itself unlawful.
Can I watermark many photos at once?
Yes. Add the whole set; each photo gets the same mark, scaled to its own size, so portrait and landscape shots look consistent. Save them individually or as one ZIP.
Which fonts can I use?
Inter, Playfair Display, Caveat (a handwriting style) or your device’s own system font. The first three are served with the site under the SIL Open Font License, so no request goes to a font service.
Are my photos or logo uploaded?
No. The watermark is drawn by your browser on this device, and the saved copies leave out the original’s camera details and GPS location.
