MisterPDF

Scan documents, merge and compress PDFs, sign and redact, all on your device. No account, nothing leaves your iPhone.

MisterPDF turns your iPhone into a private PDF workshop. Everything happens on-device: no account, no cloud, your files never leave your phone.

Features: • Scan paper to PDF with automatic edge detection and cropping • Merge multiple PDFs into one • Compress PDFs to reduce file size • Make PDFs searchable with on-device text recognition (OCR) • Sign documents with your finger and reuse your signature • Redact sensitive content permanently • Password-protect and unprotect PDFs (on-device encryption) • Reorder, rotate, extract and export pages, export as JPG • Print via AirPrint and share anywhere

Privacy first: no sign-up, no uploads to any server. Files live in the app's sandbox, protected by iOS encryption and your device passcode. We show non-personalized contextual ads and never track you across apps.
