Compress Scanned PDF
Compress scanned PDF documents — which are image-heavy by nature — using compression algorithms suited to scan characteristics like JBIG2 for black-and-white text and JPEG 2000 for colour scans.
- 1Upload the scanned PDF (image-based, typically large in size)
- 2Choose the scan type: black-and-white text or colour
- 3Set the target DPI — 150 DPI for screen use, 300 DPI for printing
- 4Click 'Compress Scanned PDF' to process
- 5Download the compressed PDF with significantly reduced file size
- Compress a 20 MB scan of a multi-page contract to under 2 MB for email

- Compress a 300-DPI archival scan to a smaller size for everyday sharing
- Reduce the size of a scanned bank statement PDF before uploading to an accounting tool
