The private, offline PDF editor for iPhone

Sheaf does everything on your iPhone. Your documents are never uploaded, there's no account to create, and it works with no signal at all.

What "on-device" means here

Every tool in Sheaf runs on your iPhone using Apple's built-in frameworks: editing, form filling, conversion, text recognition (OCR), compression and redaction. Your files stay in the app's private storage on your phone until you delete them. We don't run servers that could receive them, and we never get a copy.

What you can do, offline

Who it's for

People whose PDFs are private: contracts, invoices, payslips, medical letters, ID documents. If you'd rather not send those to someone else's server just to change a date or add a signature, an on-device editor is the simpler choice.

No account, no uploads, no internet needed. Ads in the free version never see your documents, and Pro has no ads at all.
