FAQ
Common questions and answers about this topic.
Are my photos uploaded to a server?
No. The original photo, logo, preview, and export are processed locally in your browser with HTML5 Canvas. The files do not leave your device.
What is the difference between text, logo, and tiled modes?
Text mode places one editable text mark. Logo mode places one uploaded PNG/JPG/WebP image. Tiled mode repeats text or logo across the entire image, useful for confidential drafts.
Why is SVG logo upload not supported?
SVG can embed scripts or external references. To keep the tool safe and simple, this version accepts only PNG, JPG, and WebP logo files.
When should I use tiled or diagonal watermarks?
Use tiled mode for confidential drafts, previews, or client proofs where a single corner mark is easy to crop out. The repeated pattern makes reuse harder.
Should I export PNG or JPG?
Use PNG when you need crisp text or transparent areas. Use JPG for smaller photo files; transparent pixels are flattened onto a white background.
