When to use this
Compressing a PDF helps it fit email attachment limits and upload size caps, and makes it faster to share. This tool is most effective on scanned documents and PDFs built from images — exactly the files that tend to be too large.
Private and free
Your PDF is processed entirely in your browser and never uploaded to a server, so it stays completely private.
