Compress Scanned PDF — Reduce Scan File Size
Free & secureNo signup requiredFiles never stored
Scanned PDFs are often enormous — 5-20MB for just a few pages. Our compressor aggressively reduces scanned document sizes while keeping text readable for printing and submission.
Pro Tip: Scanned PDFs are essentially images. Strong compression works best. If possible, re-scan at 150 DPI instead of 300 DPI for naturally smaller files.

Frequently Asked Questions
Why are scanned PDFs so large?+
Each page is a high-resolution image. A 300 DPI scan of one page can be 2-5MB.
How much can scanned PDFs be compressed?+
Typically 60-80% reduction. A 10MB scanned doc often compresses to 2-3MB.
Will compressed scans be legible?+
Yes. Strong compression optimizes the image while keeping text readable.
Can I OCR the compressed version?+
Yes. OCR software can still process compressed scanned PDFs.
Should I scan at lower DPI instead?+
150 DPI is sufficient for documents. 300 DPI is only needed for photos or detailed graphics.
