What is Universal File Opener?

Universal File Opener opens and edits over 100 file formats entirely on-device: PDF (fill, sign, redact, page tools, forms), Word, Excel, PowerPoint and OpenDocument, ZIP/7Z/TAR/RAR archives, images (with a full editor), audio and video, code with syntax highlighting, Markdown, SQLite databases, fonts, certificates, and unknown files as text or hex.

The app ships with no INTERNET permission, so it cannot upload your documents. No cloud conversion, no ads, no account, no analytics. The Office and PDF engines are written in-house, which keeps the download around 5 MB.

Free to try on 15 files with every feature included; a $5 one-time purchase removes the limit. No subscription.
