Add a watermark to images
Put your name or a copyright notice on photos before you share them, at full resolution, on this device.
- Nothing is uploaded
- Works offline after first visit
- Open source
- The limit is your device’s memory (phones hold less)
Adds a text watermark to photos, such as your name, a copyright line or a website, in a corner, across the middle or repeated. It is free, and your files are not uploaded: everything runs in your browser on your device. The limit is your device’s memory (phones hold less)
Done
Open the network tab. Your files never appear in it.
Add files and run the tool to see every request this tab makes.
Your files are processed on this device and never sent to a server. Reload the page to clear everything from memory.
How it works
- Drop one or more photos (JPG, PNG, WebP, HEIC, AVIF or JPEG XL), or tap to pick them.
- Type the text, choose where it goes, and set the size, opacity and colour while watching the preview.
- Download each watermarked photo at full size, or all of them in one zip.
In your browser, not on a server
Your browser decodes each photo (libheif or the Squoosh decoders step in for HEIC, AVIF and JPEG XL) and draws it on a canvas in your tab at full size. The text is drawn on top with your device’s own fonts at the chosen opacity, sized to the photo’s shorter side so the same setting looks alike on every photo, and the canvas is saved as JPG, PNG or WebP by the browser’s own encoder.
Compared with upload-based tools: Watermark sites and apps upload the photos you most want to protect, the unpublished ones, and several add their own branding on the free tier. Here the photos never leave your device, and the limit on how many you do at once is your device’s memory (phones hold less).
Verify it yourself. Give the page a short while after one visit to save itself for offline use, then turn off Wi-Fi or switch to airplane mode and run the tool again. Or open your browser's developer tools (F12, or Cmd-Option-I on a Mac), pick the Network tab, and watch it while you convert. The panel above does the same count for you.
Questions
Are my photos uploaded?
No. Each photo is decoded, drawn with the watermark and saved inside your browser tab. Your files are not uploaded, so unpublished work, client photos and pictures of your home stay on your device. The page works with Wi-Fi off after one visit and a short wait.
Which placement should I use?
Corner is the usual choice for photographers and shops: a small, readable credit that leaves the picture alone. Across the middle is harder to remove and suits proofs you send before payment. Repeated covers the whole photo in a pattern, so it cannot be cropped or cloned away; use it for images you are worried about being reused, such as ID documents sent to a landlord.
Can I watermark many photos at once?
Yes. Drop as many as you like; the same text, placement and style go on every one, scaled to each photo’s size, so a portrait and a panorama both look right. Download them one by one or as a zip.
Does it reduce the quality?
The photo keeps its full resolution. PNG saves are lossless; JPG and WebP are saved at high quality (92), which is visually the same as the original for almost all photos. Choose Save as PNG if you need it untouched apart from the watermark.
Can I add a copyright symbol or emoji?
Yes. Type or paste any text, including ©, ®, ™, emoji and non-Latin scripts; it is drawn with your device’s own fonts. On a phone the © symbol is usually on the symbols keyboard, or copy it from the default text.
Should I watermark an ID before sending it?
It is a good habit. A repeated watermark such as “For flat rental at 12 High St only, May 2026” across a passport or driving licence scan makes the copy useless for anything else if it leaks. Doing it here means the ID is not uploaded to yet another website in the process.
