Ream · Offline PDF Tools

About this app

Ream is a PDF toolkit that works entirely on your phone.

No upload. No account. No advertising. Ream has no internet permission at all, so it
cannot send your documents anywhere even if it wanted to — and neither can anyone who
gets hold of it. Everything happens on your device, offline, every time.

ORGANISE
• Merge — join several PDFs into one, in the order you choose
• Split — by page range, every N pages, or one file per page
• Page editor — reorder pages by dragging, rotate them, delete them

CONVERT
• Images to PDF — photos and scans into one document, A4, Letter or fit-to-image
• PDF to images — export pages as PNG or JPEG at the resolution you pick

SECURE
• Set password — lock a PDF, with control over printing, copying and editing
• Remove password — unlock a PDF you already have the password for

OPTIMISE
• Compress — shrink scanned documents by re-encoding the images inside them

ANNOTATE
• Sign — draw your signature, place it, and apply it to one page or every page
• Watermark — stamp text across every page, at any angle and opacity
• Page numbers — number the pages, in the corner and format you want


WHY OFFLINE MATTERS

Most PDF tools upload your file to a server. Contracts, bank statements, medical
records, identity documents — the things people most often need to merge or protect are
exactly the things that should not be sent to a stranger's computer. Ream never sends
anything, because it cannot.

Your original file is never modified. Every tool writes a new file, and results stay
inside the app until you choose to save or share them.


HONEST ABOUT LIMITS

• Ream works with standard PDFs. Some files use unusual or damaged internal structures,
and Ream tells you plainly when it cannot open one instead of producing something
broken.
• XFA forms — a type used by some bank and government documents — are refused rather
than silently emptied, because they cannot be preserved.
• Sign places a picture of your signature. It is not a digital certificate signature and
does not prove who signed.
• Compression is lossy: images lose detail permanently. Ream says so before you run it.
• If you have forgotten a PDF's password, Ream cannot recover or guess it. Nothing can.


NO PERMISSIONS FOR YOUR FILES

Ream asks for no storage permission. You pick files through Android's own file picker,
which grants access to just that document, just for that job. It cannot browse your
storage.

Ream requests permission to show notifications only so you can see progress on a long
job and cancel it. Nothing else is ever notified.
