Frequently Asked Questions

Is the watermark tool free?

Yes, completely free with no signup, no watermark on the watermark tool itself, and no usage limits.

Can I use my own logo as a watermark?

Yes. Switch to the Logo Watermark tab and upload any image — a PNG with a transparent background works best so only the logo shape appears.

Can I make the watermark repeat across the whole image?

Yes. Set Mode to Tile to repeat the watermark in a grid, or Diagonal to repeat it at an angle across the full image — both make it much harder to crop out.

What does AI Smart Position do?

It scans the image for the area with the least visual detail (lowest contrast/variance) and places the watermark there automatically, so it stays visible without covering an important part of the photo.

Is my image uploaded to a server?

No. The watermark is drawn entirely in your browser using the Canvas API. Your image is never uploaded anywhere.

Frequently Asked Questions

What opacity should I use for a watermark?

30-50% opacity is the sweet spot -- visible enough to deter reuse but not so strong it ruins the photo for legitimate viewers.

How do I add a transparent logo watermark?

Export your logo as a PNG with a transparent background, then upload it as an image watermark. The transparent areas stay clear.

Can I watermark multiple photos at once for free?

Yes -- drop all your images, configure the watermark once, and all images are processed together. Download as a ZIP.

Will watermarking reduce my image quality?

Only if you export as JPG with low quality. Export as PNG for a pixel-perfect, lossless watermarked image.
