Compress PDF to an Exact Size
Compress a PDF and reduce its file size to an exact KB — 100KB, 200KB, 400KB or any number you type — for portals that cap the whole PDF upload, without changing the page count or the text.
Processed on your device — nothing is uploaded
What it does
- Type any exact KB target, not just the common presets.
- Recompresses embedded images first; text layers stay crisp.
- Works even on scanned, image-heavy PDFs.
Private by design
Processing runs entirely inside your browser tab — your photo or document is never uploaded to a server.
Good to know
The tool works the same way on a phone browser as on a desktop one, so there's no separate app to install just to use it from a phone.
How it works
Frequently asked questions
Will this affect a text-only PDF much?
Not much — most of a PDF's size usually comes from embedded images, so a text-only file is often already small.
Does the page count change?
No — pages, order and text all stay exactly as they were; only file size drops.
