Watermark your images
Drop your images, then drag text and logo watermarks onto the canvas. Whatever you arrange is applied to every image. Nothing is uploaded.
Files are processed in your browser and never uploaded.
How to use Watermark your images
Add your files
Drop up to 500 image files onto the upload area, or tap the area to choose them from your device.
Set the options
Choose Save as and Quality. Every setting is on screen before you add a file, so you can see what the tool will do before it runs.
Run it and save
Press Process it, Don →. The button stays disabled until there is something to work on, and each file shows its own progress and result. Press Download all, Don (.zip). Each finished file keeps a name based on the one you started with, so you can tell the versions apart.
What this tool does
Watermark up to 500 images at once
Drop up to 500 PNG, JPG, WebP, GIF or BMP images and every one gets the same watermark treatment in a single run.
Add multiple text and multiple logo watermarks
Add several text watermarks and several logos at once, so a name, a URL and a logo can all go on together.
Drag, resize and rotate on an interactive canvas
Each watermark is dragged, resized and rotated on the canvas, so you position it by eye rather than by typing coordinates.
Positions apply to every image in the batch
The arrangement you make on one image is applied to every image in the batch, which is the point of doing it here rather than by hand.
Zoom in and out, preview any image from a strip
Zoom in to check the detail, and step through the strip to preview how the watermark falls on each image.
Runs in the browser, no upload
Every image is decoded, watermarked and saved inside your browser, so nothing is uploaded.
Frequently asked questions
Can it watermark 100 images at once?
Yes, up to 500 per batch. Everything runs on your device, so a big batch depends on your computer's memory and speed. On older phones or low-memory devices, very large or very many images may slow down, so just do them in smaller groups.
Are my images uploaded anywhere?
No. Everything happens inside your browser, so your photos and your logo never leave your device and nothing is sent to a server.
How do the watermarks apply to all my images?
You place text and logo watermarks on the preview image by dragging, resizing and rotating them. Their positions are stored as a share of the image, so the same layout lands in the same spot on every image in the batch, even when the images are different sizes. Use the strip under the canvas to preview the layout on any image.
Can I add more than one watermark?
Yes. Add as many text watermarks and as many logo images as you like, and arrange each one independently. Drag to place freely, use the corner handle to resize and the top handle to rotate, or tap a position preset for a quick corner or centre.
Which formats can I save to?
By default each image keeps its original format. You can also force everything to PNG, JPEG or WebP, with a quality slider for the lossy ones. The watermark is burned into the image, so it stays put wherever the file goes.
