Questions

How small will it go?

Scanned and photo-heavy PDFs usually drop by 60–90%. Text-only PDFs are already small and change little.

Will the text still be readable?

Yes. Text stays sharp; only the pictures inside are recompressed. Pick the 'light' option if you want photos to stay crisp.

Is it really free?

Yes — no account, no watermark, no limit on how many you do.
