Compress a PDF file
Large PDFs bounce off email attachment limits and slow down uploads. Compress yours down to a fraction of the size, with a choice of how much quality to trade off.
How it works
- 1Upload the PDF you want to shrink.
- 2Pick a compression level: smallest file size, balanced, or high quality.
- 3Click "Process & download" to get the compressed file.

Yes - compression only affects embedded images and internal file structure, never the actual text content.
