Frequently asked questions

Are my files uploaded to a server?: No. All image processing runs entirely in your browser on your device. Your files are never uploaded, stored, or transmitted to any server.
Will a watermark stop someone from stealing my photo?: Watermarks deter casual misuse and identify ownership, but determined users can sometimes remove them. Combine with low-resolution previews for sales galleries.
Should I use text or logo watermarks?: Logos reinforce brand recognition. Text watermarks work well for copyright notices and URLs. Many creators use both on different assets.
What opacity is best for a watermark?: 30–50% opacity is common for proofs — visible across the image but still allowing evaluation of the work underneath.
Can I tile a watermark across the entire image?: If the tool supports repeat patterns, tiling increases protection for stock previews. Otherwise place prominently over key subject areas.
Does watermarking reduce image quality?: The watermark is composited onto the image. Export at high quality to minimize additional compression artifacts.
What file format is best for logo watermarks?: PNG with transparency lets your logo float over the photo without a white box background.
