Frequently Asked Questions
Can someone remove the watermark from my image?
Strong watermarks are hard to remove cleanly. Use a tiled pattern with moderate opacity (50-70%) and a colour close to your image's midtones — this resists screenshot crops and AI removal better than a single corner stamp.
How do I add a PNG logo with transparency?
Switch to the 'Image (logo)' tab and upload your PNG. Transparency is preserved automatically — the logo's alpha channel blends with the underlying photo.
What opacity should I use for invisible-ish watermarks?
Try 20-35% opacity in tile mode for subtle protection. Visible branding usually sits at 60-80%.
Can I tile the watermark or rotate it?
Yes — toggle 'Tile across image' to repeat the watermark in a grid, and the Rotation slider tilts it −45° to +45°. Both work for either text or logo.
Are my images uploaded to a server?
No. All watermarking happens on your device using Canvas. The page is static; your bytes never leave the machine.
