What image formats can I upload?

You can upload JPEG, PNG, WebP, and GIF files. The output is always saved as PNG.

Will the watermark affect the original file?

No. Processing happens entirely in your browser; your original file is never uploaded to any server.

What does the repeat/tile option do?

It stamps the watermark diagonally across the whole image at a regular interval, a common technique to protect stock photos.

Can I drag the watermark to an exact position?

Yes. After choosing 'Custom' position you can drag the watermark preview directly on the canvas.
