I built a PDF editor because uploading private documents for simple edits never felt right
Hey,
I recently built and released PDF Editor OneX, an Android app for editing and organizing PDF files directly on your phone or tablet.
The main idea behind it was pretty simple:
I wanted a PDF tool that works fully offline, without accounts, cloud uploads, or sending personal documents to external servers just to make a quick change.
A lot of PDF apps are powerful, but many of them feel unnecessarily tied to cloud workflows. For documents like contracts, invoices, forms, insurance files, scanned letters, or anything with personal data, I really wanted the app to keep everything local on the device.
PDF Editor OneX covers common PDF tasks like editing, organizing pages, combining and splitting documents, rearranging pages, working with scans, and managing files in a mobile-friendly way.
One feature that was especially important to me is real PDF redaction — not just drawing a black rectangle over text, but actually removing sensitive content from the document so it can’t simply be selected, copied, or recovered afterward.
The biggest priority for me was data ownership:
No login.
No cloud upload.
No external server processing.
Everything stays on your device.
I’m still improving the app and would love to hear what people think, especially from anyone who regularly works with PDFs.
What would be the one PDF feature you’d expect from a mobile-first offline PDF editor?
