How to Compress PDF Without Losing Quality
Why Compress PDF Files?
Large PDF files are difficult to share via email, slow to upload to portals, and consume storage space. Compressing PDFs reduces file size while keeping the document readable and professional.
How PDF Compression Works
PDF compression reduces file size by optimizing embedded images, removing redundant data, and streamlining the internal structure. Our tool uses smart algorithms that prioritize text clarity while reducing image resolution where appropriate.
Step-by-Step Compression Guide
- Upload your PDF — Drop your file into the compressor
- Choose quality level — Select between maximum compression (smallest file) or balanced mode (best quality-to-size ratio)
- Preview and download — Compare file sizes and download the optimized version
Best Practices
- Always keep the original file as a backup before compressing
- Use balanced compression for documents that will be printed
- Maximum compression works great for email attachments and web uploads
- For scanned PDFs, compress images to 150 DPI for a good balance
