About this tool
Compress PDF helps with email attachments, application portals, document archives, and upload limits. Target size is treated as a goal, not a guaranteed claim for every document.
Practical tips
- Recommended balances size and readability.
- Use Target size only when a portal has a firm limit.
- Always review small text after stronger compression.
Frequently asked questions
Can you guarantee an exact target size?
No. The tool reports whether the target was reached and provides the best safe result when it was not.
Why are some PDFs hard to compress?
Files that are already optimized or contain complex graphics may have limited safe reductions.
