Frequently asked questions

Can any PDF be compressed to 150 KB?

Most scanned and image-heavy PDFs fit easily. If a file can't reach 150 KB without becoming unreadable, we show the smallest size we could reach.

How do I keep the best quality?

Scan at 150–200 DPI instead of 600 DPI — it looks the same on screen and compresses far better.

Is my document uploaded?

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