Help & clarification
Frequently Asked Questions
Can I use my logo as a watermark?
Yes. Switch to “Logo / Image” and upload a PNG — transparent logos give the cleanest result.
How do I stop people cropping out my watermark?
Enable “Repeat across the whole image” to tile the mark diagonally over the entire photo.
Are my images uploaded to a server?
No. Every operation runs locally in your browser using the HTML5 Canvas engine. Your files never leave your device, so they stay completely private.
Is this tool free to use?
Yes — it's completely free with no sign-up, no watermarks added to your output and no daily limits.
