Compress a PDF to an exact size
Portals and email servers give you a hard number — 100 KB, 200 KB, 500 KB. Set that number here and the compressor works down to it page by page, in your browser, with no account and nothing uploaded.

How to compress a PDF to a set KB
- 1
Add the PDF
Drop your file onto the compressor. It is opened locally in this tab — nothing is uploaded to a server.
- 2
Choose your exact target
Switch to 'Exact target size' and pick 100 KB, 200 KB, 500 KB or type any number the upload form demands.
- 3
Let it find the best pass
Each page is re-rendered at progressively lighter settings and the first result that fits your budget is the one you get, so quality is never thrown away needlessly.
- 4
Download
You get the compressed PDF plus its real final size, so you can confirm it fits before uploading anywhere.
Honest limits
Compression works by re-rendering pages, so a 40-page colour scan cannot honestly become 100 KB. When a target is out of reach you get the smallest clean result instead of a broken file, and the page tells you exactly what it managed. Splitting the document first usually solves it.
