Universal Converter is a free-to-use app that converts images, documents, videos and audio, builds and signs PDFs, fills in forms and pulls tables into Excel. Everything happens on your own device: your files are never uploaded anywhere.
It runs on Windows 10 and 11, Mac (Apple silicon) and Android 10 or newer, in English, Greek, Spanish, Italian, German, French, Portuguese, Polish, Russian, Arabic, Hebrew, Simplified Chinese, Japanese, Korean, Tamil, Afrikaans, Yoruba and Hausa.

- Install it on your device.
- Pick a tab: Documents & PDF, Images, Video, To Excel or Sign.
- Drag files or folders into the window, or click Add files (Ctrl+O, ⌘O on a Mac).
- Choose the format and options, then click Convert (Ctrl+Enter, ⌘Enter on a Mac).
Results are saved next to the originals, or in the folder you choose in the Save to box at the bottom.
If you add files that another tab converts, the app tells you which tab and takes them there with one click. On the About tab, each tool's How to use button opens its instructions.
