Frequently asked questions
- Is my image uploaded to a server?
- No. Everything happens in your browser using the Canvas API — your image never leaves your device.
- Which image formats are supported?
- JPG, PNG and WebP keep their original format. Any other image type is saved as PNG.
- What does the Repeat option do?
- When Repeat is on, the watermark is tiled diagonally at a 30° angle across the whole image at regular intervals — useful for copyright protection.
- Can I change the watermark color and transparency?
- Yes. Use the color picker to choose any color and the opacity slider (10–100%) to control how transparent the watermark is. A semi-transparent white or grey watermark is a common choice.
- Will the watermark reduce image quality?
- PNGs are always lossless. JPGs and WebPs are re-encoded at 95% quality, so the difference is imperceptible.
