How to use Optimize PDF
- Choose or drag in your PDF.
- Tick deep clean if you want unused data removed too.
- Press Optimize PDF and download the result.
Tidy the file without touching the pages
PDFs edited many times often carry leftover objects and an inefficient structure. Optimize PDF rewrites the file with compact object streams, which usually makes it smaller and quicker to open, especially online. Unlike Compress PDF, the pages are not redrawn, so text stays sharp and searchable.
Private by design
Optimize PDF runs entirely in your browser. Your file is processed on your own device and is never uploaded to a server, there's no sign-up, and the result is ready to download as soon as it's done.
Questions
How is this different from Compress PDF?
Optimize keeps every page exactly as it is. Compress rebuilds pages as images to make scans much smaller.
What does deep clean remove?
Anything not needed to show the pages, including bookmarks and form fields.
Why didn't my file get smaller?
It was already well built. For a big size drop, try Compress PDF.
