Compress a PDF to 100 KB

A 100 KB limit is common on application portals. Enter 100 KB as the target in ScanifyAI and the tool lowers image quality gradually until the PDF fits, showing you the result before you download.

Nothing is uploaded – the compression runs on your own device.

Frequently asked questions

Will the text stay readable?

Real text stays sharp. Scanned pages are images and get softer as the size goes down – always check the preview.

Is my PDF uploaded?

No. Compression runs in your browser on your own device, so private documents never leave it.

Does it work for scanned documents?

Yes – scans shrink the most, because they are mostly images. Scanning in greyscale instead of colour often halves the size again.

Is there a page or file limit?

There is no account limit. Very large files depend on your device’s memory; close other tabs if a big file is slow.
