Questions
Will the text still be readable?
Yes. Compression rewrites images and removes duplicates; text stays vector-sharp.
Is it free?
Yes. On-device tools are free: five documents a day, no account. Cloud tools have a free daily allowance; Premium removes both limits.
Where does my file go?
On-device tools never send it anywhere. Cloud tools upload it over an encrypted connection and delete it within 60 minutes.
