What is the indox conversion catalog?
The conversion catalog is the full list of file conversions indox can run. It covers 5,963 format pairs from 348 source formats, grouped as images, documents, ebooks, video, audio, archives, fonts and 3D models.
Each row is one source format, the format your file is in now. The tags beside it are the formats it can become. Choose a tag to open the page for that pair, drop your file there and download the result.
The most used conversions, such as HEIC to JPG, DOCX to PDF and MOV to MP4, sit at the top of the first page. Every source format then follows in alphabetical order, a page at a time. Search takes a format name, or a pair such as heic to jpg.
