Frequently asked questions
What image formats can I use?+
PNG and JPG images work, and a transparent PNG looks cleanest as a watermark.
Can I make the logo subtle?+
Yes. Lower the opacity so the logo sits gently behind your content.
Are my PDF and image uploaded anywhere?+
No. Both stay in your browser — nothing is sent to a server.
Is the tool free?+
Yes, completely free with no sign-up and no extra watermark.
