Add watermark to photos
Stamp text or a logo on many photos at once. Choose the position, size, opacity and angle, or tile it across the whole picture.
🔒 Your files are never uploadedThe first photo is shown as a preview. The same settings are applied to every photo.
Before watermarking you can resize with compress image; afterwards remove photo location strips camera data for a publish-ready photo. For PDF documents use PDF watermark.
Why do it in the browser
The photos people watermark are the ones they are about to publish — product shots, portfolio work, pictures of their children on a blog. Most "watermark online" services start by uploading the originals, unmarked, to a server you know nothing about. Here the stamping is done by your own browser: nothing leaves your device, the page keeps working offline, and there is no limit on how many photos you process. A small mark in a corner looks best but is easy to crop off; a tiled mark cannot be removed but covers the picture. Product photos usually take a corner mark; anything you do not want reused takes the tiled one.
Frequently asked questions
Are my photos uploaded anywhere?
No. Photos are opened, stamped and saved entirely inside your browser. The page keeps working with the internet switched off, which is the easiest way to check. That is also why dozens of photos finish in seconds — there is no upload.
Why is the mark a different size on each photo?
Size is set as a share of the photo's width, not in pixels. A 4000-pixel photo and an 800-pixel photo both get a mark a quarter of their width at 25%, so a batch looks consistent. Pixel sizes would make the mark huge on small images and invisible on large ones.
My logo appears inside a white box
The logo file has a white background baked in. Use a PNG with a transparent background — export it with "transparent background" or "alpha channel" from the program that made it.
Can the watermark be removed later?
Not from the saved file: the mark is drawn over the original pixels. Your original photo is untouched, so keep it and publish only the watermarked copy.
Does saving reduce quality?
With "Same as the original", JPG photos are saved as JPG at 92% quality and PNG as PNG. Dimensions are never changed. Even with a transparent logo, JPG is fine because the background is the photo itself.
Does it work on a phone?
Yes. Several photos are delivered as one ZIP, because phone browsers often keep only the first file of a series of downloads.
