About This Tool
One megabyte is the most common upload limit on the web - job boards, school systems, and email services all use it - and PDFs full of scans and photos blow past it quickly. This tool compresses PDFs to 1MB or less while keeping text readable and pages intact, entirely in your browser. Hit the 1MB bar on the first try, every time.

Frequently Asked Questions
Why is 1MB such a common PDF limit?
Because it balances usability with storage: a 1MB PDF is small enough to store by the thousands and quick to download, yet large enough for most text and image documents.
Can a scanned contract fit under 1MB?
Usually yes. Scanned pages are images and compress very well - the High level handles long scans that would otherwise exceed the limit.
What level should I use for a typical document?
Medium is the best default for most PDFs: strong size reduction with no visible change to text. Switch to High only when the 1MB target is out of reach.
