How to Compress a PDF Online

FileForge's PDF compressor reduces file sizes by stripping metadata, optimizing document structure, and recompressing embedded images — all while keeping your document readable and fully functional.

Three Compression Levels

• Low — Minimal compression. Best for print-quality documents where every pixel counts.
• Medium — The sweet spot. Typically reduces file size 20–50% with no visible quality loss for screen viewing.
• High — Maximum compression. Best for documents that will only be read on-screen or sent via email.

Why Compress PDFs?

Large PDFs cause email attachment failures, slow down website load times, and waste storage. A compressed PDF is easier to share, faster to upload, and takes less space on any device — with no functional difference from the original.

What Gets Optimized

• Embedded JPEG images are recompressed at the selected quality level
• Document metadata (author, title, keywords) is stripped
• Object streams are repackaged with compression for smaller cross-reference tables

Your Privacy

Files are processed on our servers and immediately discarded. We never store, index, or share your documents. Your PDFs never leave the compression pipeline.
