About this tool
What this tool does
Compress PDF reduces file size while preserving readability—exactly when you need to compress PDF for email attachment limits, intranet uploads, or mobile review. It supports preparing reports and handoffs without forcing a server-side upload.
Real-world use cases
- Staying under Outlook or Gmail size caps when sending a merged proposal.
- Shrinking discovery or compliance PDFs before portal submission.
- Speeding up sync to shared drives on VPN-heavy document workflows.
Privacy explanation
Optimization runs against the PDF bytes in your tab; you do not need to ship the entire file to a third-party “compressor” service to get a smaller download.
Browser processing
The engine rewrites streams and structure where possible in-memory, then emits a new PDF—throughput follows your device, not a remote queue.
