About Compress PDF

Shrink your PDF file size so it's easier to email or upload. Text stays sharp.

Frequently Asked Questions

What compression levels are available?
Three: Extreme (maximum size reduction), Recommended (good balance of quality and size), and Less Compression (highest quality with modest size savings). Recommended works best for most use cases.
Will compressing blur the text in my PDF?
No. Compression targets images and metadata inside the PDF. Text, vector graphics, and formatting stay completely sharp. You'll typically see a 30-70% reduction in file size.
Can I compress multiple PDFs at once?
Yes. Upload several PDFs and they're all compressed with the same settings. Download the results individually or together.
Can I see how much smaller the file got?
Yes. After compression, the tool shows the original and compressed file sizes side by side so you can see exactly how much space you saved.
Can I rotate pages while compressing?
Yes. If any pages are in the wrong orientation, you can rotate them as part of the compression step — no need to use a separate tool.
