FAQ

Are my images uploaded to a server?
No. All processing happens locally in your browser, on your own device. Your images and watermark data are never sent to or stored on any server.
How many images can I watermark at once?
There is no fixed limit — you can process as many as your device memory allows. For very large batches or many high-resolution images, processing in a few smaller batches is recommended.
Can I use a logo image as the watermark?
Yes. Choose the "Image" type and load your logo. A transparent PNG blends in cleanly.
What is the tiled layout?
It repeats the watermark across the entire image. Even if part of the image is cropped, the watermark remains, making it much harder to reuse without permission. Spacing and rotation are adjustable.
Does the image quality degrade?
Saving as PNG is lossless. For JPEG/WebP you can control compression with the quality slider. The original resolution is preserved while the watermark is composited.
Is it free? Do I need to register?
It is completely free with no registration or installation required. Just open it in your browser and start using it.
