PDF Under: Compress & Resize

Compress any PDF to an exact size — 500 KB, 2 MB, 5 MB, or custom. Text and vectors stay sharp. 100% on-device, no uploads, no accounts.

Need your PDF under a specific size? PDF Under compresses your file to fit your exact target — 5 MB, 2 MB, or any limit you're given. No more guessing with vague "high / medium / low" quality sliders.

HOW IT WORKS Pick a target size — from 500 KB to 10 MB, or set a custom number. PDF Under shrinks your file toward that exact target, showing you the result before you save or share it.

SHARP TEXT, SMALLER FILES Most compressors flatten your whole document into blurry images. PDF Under is different: text and vector content stay untouched. Only the embedded photos and scans inside your PDF are compressed — so your document stays sharp and, whenever possible, still selectable.

WHEN A TARGET IS TOO AGGRESSIVE If your target size would make the content unreadable, PDF Under won't silently ruin your file. It shows you the smallest version that's still readable, tells you exactly why, and lets you preview real pages before you decide. Want the exact size anyway? You're always in control — force it through with one tap.
