How to Compress Multiple PDFs at Once

If you have many PDFs to compress, here's how to handle it efficiently.

Online Tool Approach

For 5-10 files, process them one at a time:

1. Compress the first PDF
2. While downloading, upload the next
3. Use consistent naming ("filename-compressed.pdf")

Tips for Batch Processing

• Organize first — Group by compression needs
• Use consistent settings — Same level per group
• Process largest first — They benefit most

For Large Batches (50+ files)

Desktop tools like Adobe Acrobat's batch processing may be more practical. But for most users, one-at-a-time browser processing is faster than installing new software.

Automation Options

For regular batch processing, consider scripting solutions using tools like Ghostscript or PDFtk. These command-line tools can be automated with shell scripts.
