A visible mark is a deterrent
A watermark makes reuse obvious but does not make an image impossible to crop. Keep the original and a version without the mark for licensing work.
Image tools
Put your name across the picture.
Add a quiet credit, a copyright line, or a logo to a photo before sharing it. Choose a corner or tile the mark across the frame; the image stays local.
No upload. No account. Files stay on your device. The processing happens in this browser tab—an unusual arrangement in a category full of upload forms.

Design the watermark
#FFFFFF
The mark becomes part of the pixels, so it cannot be switched off afterwards. Keep the original if you may need a clean copy later.

The short version
How it works.
No installer, no sign-up, and no second app to open. The work happens in the browser you already have, using the file already on your device.
-
Choose the photo
Open a JPG, PNG, or WebP image. Transparent PNGs stay transparent in the output.
-
Add the mark
Type a credit or choose a logo image. Move it to a corner or repeat it, then adjust opacity, size, and angle.
-
Download the result
Save a new image with the watermark baked into the pixels. The original file is never modified.
Fine print, without the runaround
Good to know.
Every tool has a boundary. These are the ones worth knowing before you start, so the result is not a surprise.
Use a transparent logo
A PNG with transparency sits over the photo without a rectangular box. White or black marks with reduced opacity work on most images.
Can I place my logo instead of text?
Yes. Choose the image watermark option and add a PNG or JPG logo. A transparent PNG gives the cleanest result.
Does the watermark reduce image quality?
The image is redrawn and saved once. At high quality the loss is minimal, but always start from the original rather than a previously watermarked copy.
Can I tile the watermark across the whole image?
Yes. Enable the repeated pattern option to place the mark in a grid. Adjust spacing and angle to make it effective without making the photo hard to see.
