Frequently asked questions
Can it watermark 100 images at once?
Yes, up to 100 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.
