About this tool
Reduce PDF file size for email, forms, upload limits and easier sharing.
What this tool does
The tool tries to reduce PDF file size by optimizing document structure and resources stored inside the file.
When to use it
Use it when a PDF is too large for email, application forms, order systems, customer portals or archives.
How to read the result
The largest savings usually come from documents with scans or large images. Already optimized PDFs may shrink only slightly.
Privacy and processing
The PDF is uploaded to the server only to complete the current compression task and is not intentionally stored afterward.
Limitations
Not every PDF can be compressed strongly without quality loss. Password-protected documents may need to be unlocked first.
Compress PDF for email and upload limits
Use this when a PDF is too large for email, an online form or a document portal. Try a lower DPI or stronger compression for scanned documents, then check that text remains readable.
How to use
- Choose a PDF file.
- Select compression level.
