Compress PDF, Shrink & Slim

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.
