Frequently asked questions

Yes. Switch to "Logo" mode and upload your logo image (PNG with transparency recommended). Set the size as a percentage of the image width and choose a position.

Yes. Select multiple images and the same watermark settings will be applied to all of them. Download as a ZIP when done.

Yes. Use the Opacity slider — 60% is a good default that protects your images while not being too intrusive. Lower opacity for subtle watermarks, higher for clearly visible ones.

No. All processing happens in your browser using the Canvas API. Your images and logo never leave your device.

Impact is the traditional watermark font — bold and clearly readable even at lower opacity. For a more elegant look, try Georgia (serif). For a technical/copyright feel, Courier works well.

The output format matches the input. JPG in → JPG out, PNG in → PNG out. PNG transparency is preserved (the watermark is composited on top).
