Slim : Compress PDF

Make any PDF small enough to email or upload — in seconds, on your iPhone. Your files never leave your device. Compress, merge, split, organize, and more.

Slim makes your PDFs smaller — right on your iPhone, in seconds.

When a file is too big to email, upload, or attach, Slim shrinks it down to fit. Pick a quality, or set an exact target size (like "under 5 MB") and Slim compresses to hit it. You see exactly how much smaller it got, with a full preview, before you save.

PRIVATE BY DESIGN Your files are processed entirely on your device — nothing is ever uploaded, nothing leaves your iPhone. No account. No sign-up. IDs, contracts, tax forms, medical records: they stay yours.

EVERYTHING IN ONE TIDY TOOLKIT

• Compress — shrink any PDF; choose a quality or a target size
• Merge — combine several PDFs into one
• Split — pull out the exact pages or range you need
• Organize — reorder and delete pages
• Image → PDF — turn photos into a clean PDF

HONEST RESULTS If a file is already small, Slim won't wreck it just to look busy. If it can't hit your exact target, it tells you the smallest it could reach — no fake numbers, and never a watermark on your document.

Save to Files or share anywhere — AirDrop, Mail, Messages, and more.

Slim. Smaller PDFs, kept private, done in seconds.
