- Tiled watermarks are harder to crop out.
- Use a PNG logo with a transparent background for the cleanest look.
Questions & answers
Can I add a logo as a watermark?
Yes. Choose “Image / logo” and pick a PNG or JPG; transparent PNGs look best.
Is it really free?
Yes. Every Feemag tool is free, with no sign-up, no watermarks added by us and no daily limits.
Are my files uploaded anywhere?
No. Your files are processed by your own browser on your device and never uploaded to a server. That also makes it fast, even on big files.
Does it work on my phone?
Yes: in any modern browser (Chrome, Safari, Edge or Firefox) on iPhone, Android, Mac, Windows and Linux.
