Reduce PDF File Size Without Losing Quality
Large PDF files slow everything down — they're rejected by email servers, take forever to upload, and eat up valuable storage space. Our PDF compressor uses intelligent compression algorithms to shrink your file to the smallest possible size while maintaining sharp, readable text and clear images. Most files are reduced by 40–80% without any visible quality loss.

Frequently Asked Questions
How much will my PDF be compressed?▾
Compression depends on your PDF's content. Files heavy with images typically reduce by 50–80%. Text-only PDFs may reduce by 20–40%. Our tool shows you the exact before/after sizes.
Will compression affect text quality?▾
No. Text in PDFs is stored as vector data and is unaffected by image compression. Only embedded images are compressed — and we use smart algorithms that maintain readability.
Is there a file size limit?▾
Free users can compress files up to 25MB. Premium subscribers can compress files up to 500MB.
Can I compress a PDF multiple times?▾
Yes, but diminishing returns apply. The first compression delivers the biggest reduction. Subsequent passes typically reduce size by only a small percentage.
