Common questions
Is Chat with PDF free to use?
Yes. OhhPDF has no signup, paid tier, processing fee or daily usage quota. Device memory and each tool’s format and resolution limits still apply.
Do my files get uploaded?
No. Processing runs on your device. If you choose the P2P sharing or whiteboard tools, data goes directly to the peer you pair.
Can I use it offline?
Load the tool and any required model once while online. Once its assets are cached, supported browsers can reuse them offline. Clearing site data removes that cache.
