Compress PDF

Absolutely! Our PDF compression tool runs entirely in your browser. Your files never leave your computer and are not stored on any server. We prioritize your privacy and security.

You can compress PDF files up to 25MB in size. This limit ensures fast processing and optimal performance for all users.

Compression errors usually occur due to:

• Password-protected PDF files
• Corrupted PDF files
• PDFs with complex vector graphics
• Files that are already highly compressed

Try resetting and uploading the file again. If the problem persists, try a different PDF.

Compression rates vary depending on your file content. Text documents typically compress by 50-70%, while image-heavy PDFs may see 20-40% reduction. We always prioritize quality retention.

Our compression algorithm is optimized to maintain visual quality while reducing file size. For documents containing images, we use smart downsampling to preserve readability.
