Frequently Asked Questions
About the watermark tool
Which image formats can I watermark?
You can add a text watermark to HEIC, JPG, PNG, and WebP images. HEIC is converted to JPEG; PNG and WebP keep their original format.
Will a watermark lower my image quality?
JPEG output uses 92% quality by default to preserve detail. PNG output is lossless, so adding a watermark does not add compression artifacts.
Are my images uploaded?
No. Processing happens locally in your browser, so your images are never sent to a server.
Can I watermark several images at once?
Yes. Select multiple files, set up your watermark once, and apply it to the whole batch. Download them individually or as a ZIP.
Which watermark settings can I change?
You can change the text, font size (12–120px), color, opacity (5–100%), position (center or any corner), and rotation angle (-45° to 45°).
