Smart On-Device CompressionScanOrbit Pro

Compress and Shrink PDF File Size on Android

Q: Will compressing my PDF make the text unreadable?

No. ScanOrbit’s compression algorithm specifically isolates text vectors and applies selective image compression, keeping fonts sharp and legible.

Q: Does the compression tool work on scanned receipts and contracts?

Yes! Scanned documents usually contain high-resolution camera images that take up 10–25 MB. ScanOrbit can typically reduce these to under 2 MB with excellent readability.

Reduce bulky scanned PDFs to email-friendly file sizes without turning text blurry. Choose between High, Medium, and Low compression tiers running completely offline.
