About this size target
If your source is already near 5 MB, the tool may only shave metadata or slight redundancy — results always depend on content.
Privacy-first: analysis and compression use WebAssembly/JavaScript locally.
How to use
- Drop in your oversized PDF.
- Confirm 5 MB is the active target.
- Compress and compare original vs output labels.
- Download and retry with a lower target if the portal still complains.
FAQ
- How do I compress PDF to 1MB?

- Why can't some PDFs reach the target size?
- Already-optimized PDFs may not shrink much. Scanned books need smaller page dimensions or fewer pages to move the byte count a lot.
- Is my PDF stored?
- We do not store your PDF; processing stays on your device.
- How does PDF compression work?
- Rasterization plus JPEG tuning lets the tool iterate quality until the packed file nears your requested megabytes.
- Is this tool free?
- Yes, you can use it without payment or signup.
