File formats
An encyclopedia of extensions: what a format stores, how to open it on Windows, macOS, Linux and your phone, and what and how to convert it to.
Everything about files: how to open, convert, find and protect them
Every day we deal with dozens of extensions — from the familiar PDF and DOCX to the exotic DWG, HEIC and SQLite. Loadfile breaks them down in plain terms: what the format is, which program opens it, how to convert it to another form without losing quality.
