App animation: on the Compress screen you pick Balanced, tap Compress and the PDF gets lighter, for example from 8.4 MB to 1.2 MB, ready to share.

Why do it in Prelo PDF

  • Three clear levels

    Light for reading on screen, Balanced for sending, Very small for forms with a size limit.

  • No surprises

    The original doesn’t change. If the file doesn’t get smaller, the app tells you.

  • Nothing goes to a server

    Contracts and payslips are shrunk on the device, never through a website.

How it works

  1. Pick the PDF

    Open Compress and pick the file that needs to be lighter.

  2. Pick a level

    Balanced handles most uploads. Very small is for tight limits.

  3. Share it

    See before and after, then send the new PDF by email, WhatsApp or upload form.

Your file never leaves your iPhone

PDF websites ask you to upload your file to their servers. In Prelo PDF, everything is processed on the device, even in airplane mode. A file only leaves when you tap Share and choose where it goes.

  • 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.

Questions

How much smaller will it get?

It depends on the file. PDFs with photos and scanned pages usually shrink more; if it’s already light, the app tells you and keeps the original.

Is the text still selectable?

At Light and Balanced, yes. At Very small the text becomes an image, and the app warns you first.

Can anyone else see my files?

No. Prelo PDF shares nothing with websites or servers. A file only leaves your device when you tap Share and choose where it goes.
