关于 压缩 PDF 的常见问题
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.
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.
