How to Compress PDF to 800 KB

What does a 800 KB target mean?
The 800 KB target ensures color scans, embossed seals, and transcript grids stay completely clear while eliminating excess DPI and scanner color noise.
Capacity: Color scanned documents fit approximately 8 to 15 pages. Grayscale scans fit 20 to 35 pages under 800 KB.
Is the output size exactly 800 KB?
The 800 KB limit is an absolute ceiling. Output files finish under 819,200 bytes.
Troubleshooting & Tips
If a scanned PDF exceeds 800 KB, consider converting color pages to grayscale if color is not mandatory, or reduce the scan DPI before compression.
Why PDF files grow larger than 800 KB
A multi-page color scan at 300 DPI generates 2 to 4 MB per page. A bundle of diplomas, transcripts, and ID cards can easily exceed 15 MB straight from a scanner.
Visual quality expected at 800 KB
Fine print, table borders, and official notary stamps remain sharp and clearly identifiable on both mobile screens and desktop monitors.
