Use case
Compress Scanned PDF Without Losing Text
Reduce scanned PDF file size while preserving text readability using OCR-aware workflow steps and compression sequencing.
Implementation guidance
Scanned PDFs are usually image-based, so normal compression can quickly make text fuzzy. This is why many users think compression always destroys readability. The better approach is to combine OCR and compression in the right order.
Run OCR to create a searchable text layer, then compress with balanced settings and review small-font areas. OCR does not magically fix bad scans, but it helps preserve usability and search behavior while reducing size.
FoxyPDF supports this practical sequence: OCR first for recognition, then compress for size, then validate output on desktop and mobile before sharing.
Step-by-step workflow
4 steps- 1Upload scanned PDF to OCR and select the best language.
- 2Generate searchable output and download the OCR version.
- 3Compress the OCR output with balanced settings first.
- 4Review small text and rerun with stronger profile only if needed.
FAQ
Why does scanned PDF compression blur text faster than normal PDFs?
Because scanned pages are images. Compression primarily reduces image data, which directly impacts text sharpness.
Does OCR reduce file size by itself?
Not always. OCR improves text usability; compression is still required for meaningful size reduction.
What is the best order: OCR then compress, or compress then OCR?
OCR first is usually safer for readability and searchable output quality.
Can I keep print quality on scanned forms?
Use moderate compression and verify printed output, especially for low-contrast scans.
