Free, fast and private Compress PDF
Compressing a PDF is essential when a portal, a university or an email provider limits attachment size. FreePDF offers three levels: “Lossless” optimizes the internal structure without touching content; “Recommended” recompresses embedded photos and scans while keeping text intact; and “Extreme” aims for the smallest possible file, even turning pages into images.
Compression uses your own device, so it does not depend on your upload speed. If the result is not smaller than the original, you get the original back so you never lose quality for nothing.
- Up to 90% smaller for scans
- Keeps text selectable
- Several files at once

Why does FreePDF process everything on your device?
Unlike other services, FreePDF never uploads your documents to a server: the tool is downloaded to your browser and uses the processor of your own computer or phone. The result: more privacy, more speed (no waiting for uploads or downloads) and a service that is free forever, funded by a short ad.
Frequently asked questions
Which compression level should I choose?
For digital text documents use “Lossless”. For scans or PDFs with many photos, “Recommended” gives the best balance. “Extreme” is for when you need the smallest possible file.
Will the text remain selectable?
Yes with “Lossless” and “Recommended”, which only recompress images. “Extreme” may turn pages into images; if you need selectable text afterwards, use OCR PDF.
Are my files uploaded to a server?
No. FreePDF processes files directly in your browser using your own device. Documents are never sent over the internet, which makes it the most private and fastest option.
Is it really free?
Yes, 100% free with no sign-up. FreePDF is funded by a short ad shown while your file is processed; its length depends on the size and complexity of the job.
