Also in the app: scan to PDF, sign, organize pages, images to PDF, PDF to images, edit metadata, and an on-device AI chat. All tools
Sign a PDF in half a minute.
Draw your signature once, place it, save. This is the real app on an iPhone, start to finish.
Your files stay on your phone.
Online PDF tools have to upload your file before they can work on it. ProperPDF does the same jobs on the device, which matters for tax forms, contracts, IDs and medical letters.
Don't take our word for it: turn on airplane mode and merge a PDF.

Questions
Anything else: support.
Do my PDFs get uploaded?
No. ProperPDF processes every file on your phone or tablet. There is no ProperPDF server that receives your documents.
Does it work without internet?
Yes. Every PDF tool works offline. The on-device AI chat needs a one-time model download on some devices before it works offline.
What's free and what needs Pro?
Scan, merge, split, organize and convert are free. Merge and split add a watermark unless you have Pro, and on Android most free tools do. Compress, sign, fill forms and lock need Pro. Full list.
Which devices does it run on?
iPhone and iPad with iOS 17 or later, and Android phones and tablets with Android 8.0 or later.
