FAQ

Which PDF compressor should I use?

Use PDF Compressor for the main browser-local tool, Compress PDF for the common search phrase, Reduce PDF Size or PDF Size Reducer for size-focused checks, and Compress PDF Online for that search entry.

Will this always make my PDF smaller?

No. Some PDFs are already optimized or contain content that cannot be reduced much in the browser. The tool reports the result instead of promising a smaller file.

Are PDFs uploaded to a server?

The PDF compressor tools are designed to run in your browser after the page loads, with file limits to protect performance.
