Staple Free
Enrollment, legal paperwork, HR onboarding: they always want everything in one PDF.
Pick the files, drag them into order and staple. Out comes a single PDF, every page in place.
Nothing leaves your device
Your documents as PDFs, ready to send. Right from your iPhone.
Combine documents into one file, make a PDF light enough for email or WhatsApp, and scan paper without a scanner. All offline, no account: your files stay on your device and only leave when you tap Share.

Why Prelo PDF
Actually private
Everything is processed on your device. Nothing goes to servers or websites, and a file only leaves when you share it.
Works without internet
In airplane mode, on the subway or with no signal: the app keeps working.
No account, no sign-up
Open it and use it. No email, password or login to remember.
Nothing leaves your device
Your documents stay on your device. Not even our servers see them.
To merge or compress a PDF on a website, you send the file to someone else’s server. Your ID, contracts, payslips, medical results. With Prelo PDF, everything happens on your device, and nothing is shared with websites or servers without your say-so.
Processed on your device
Merging, compressing, splitting and scanning happen on the device itself, with no internet.
Nothing goes to websites or servers
Prelo PDF doesn’t send your files, or data about them, to anyone. Not even to us.
It only leaves when you share it
A file leaves your device only when you tap Share and choose where it goes.

Scan Free
The contract is on paper and there’s no scanner nearby.
Point your camera: the iPhone’s document scanner crops the page and you get a clean PDF.
Photos to PDF Free
You photographed your documents and now they want a PDF.
Pick the photos and they become pages of a single PDF. The app only sees the photos you pick.
Split Pro
You only need to send two pages out of forty.
Split into parts or pull out just the pages that matter.
Organize Pro
A page upside down, out of order or one too many.
Rotate, delete and reorder pages until the file is just right.
Password PDFs Free
Your bank statement or payslip arrived password-protected.
Type the password once to open the PDF and use it with the other tools. It’s used only on the device and never stored.
