What PDF 123 is

PDF 123 is a free, ad-supported Android app for converting, merging, splitting, compressing, signing and editing PDF files. The tools run on your device; see the privacy policy.

Your files

Your files stay yours. You are responsible for the files you open with the app and for having the right to convert or change them. Keep a copy of important documents: a conversion or edit can give a result that differs from the original.

Using the app

You may use the app for your own personal or work use. Please don't copy, resell or reverse-engineer it.

Ads and paid features

The app shows ads from Google AdMob, as described in the privacy policy. Some features may later be offered for purchase through Google Play. Prices and what each purchase includes are shown before you buy, and Google Play's terms apply to the payment and refunds.

No warranty

The app is provided "as is". To the extent the law allows, we are not liable for any loss arising from its use, including lost or damaged files.

Changes

These terms may be updated; the new version is published on this page with a new date. Questions: contact form.
