What This Processing Changes
The PDF is rewritten with compression settings that can reduce embedded image data. Text-heavy files may shrink less than scanned or image-heavy documents.
How to Check the Result
- Expect one readable page.
- A small text-based PDF may get larger when rewritten; compare actual bytes.
Limits and Troubleshooting
- A target size is best effort and may not be reachable without unacceptable image degradation.
- Open the result and verify small text, forms, links, and every page before submission.

Worked Example: Try medium compression on a one-page digital table.
- Upload table.pdf.
- Choose medium compression without an exact target size.
- Download and compare the byte sizes and every table entry.
