Frequently Asked Questions (FAQs)
Q: Can I add both text and a logo watermark?
A: You can easily switch between Text and Logo mode to apply your desired branding, or stamp multiple watermarks by re-running the tool.
Q: What is Repeating Mosaic / Tile Mode?
A: Tile mode creates a repeating grid of semi-transparent watermarks diagonally across the entire photo, making it impossible for someone to crop out your copyright mark.
Q: Does watermarking reduce the original image quality?
A: No! The tool renders the watermark directly onto the original pixel canvas in full source resolution without unnecessary downscaling.
Q: Can I watermark multiple photos at once?
A: Yes! You can upload multiple JPG, PNG, and WebP photos together and download all watermarked files in a single ZIP package.
Q: Are my photos uploaded to any server?
A: No! All canvas stamping and rendering happen 100% locally inside your web browser sandbox. Your images never leave your computer or phone.
