Compress PDF Online Free Instantly - Reduce File Size

Large PDF files are hard to email, upload, and share. Our free PDF compressor reduces file size quickly while preserving readability. Choose from several quality presets to balance size and clarity for screen viewing, ebooks, printing, or prepress.

conv.whatis_title

This tool is an online PDF compressor. It uses Ghostscript to rewrite your PDF with different compression settings, removing redundant data and lowering image resolution according to the preset you choose. The process is automatic and runs entirely on our secure servers.

conv.whyuse_title

Email services and websites often limit attachment sizes. Compressing your PDF makes it easier to share, faster to upload, and cheaper to store. Our tool gives you control over the compression level so you can pick the best trade-off for your needs.

conv.about_title

Our PDF compressor works with all standard PDF documents.

Simply upload your file, choose a quality preset, and download the compressed PDF. The 'Screen' preset gives the smallest file for web and email, while 'Prepress' keeps the highest quality for professional printing.

Your file is deleted from our servers automatically after one hour, and no copy is kept.
