Frequently asked questions

Can any PDF be compressed to 50 KB?

Single-page scans, ID cards and certificates usually fit. Long documents with many pages may not reach 50 KB; we'll show the smallest size possible.

How do I keep the best quality?

Scan in black and white or grayscale rather than color; it leaves more room for sharp text at 50 KB.

Is my document uploaded?

No. Compression happens entirely in your browser — the file never leaves your device.
