About IN files
An .in file is most commonly a plain text input file used to feed data into a program. It is widely used in competitive programming platforms like Google Hash Code, GNU Autoconf build scripts, and generic command-line utilities. However, the .in extension is completely unstandardized, meaning developers often repurpose it. For example, the ColorNote Android app uses .in files to store backups, which are actually disguised ZIP archives. Similarly, GoPro cameras use .in files to save Wi-Fi configurations in JSON format, and the Italian tax agency (Agenzia delle Entrate) uses it for specialized certificates. The main disadvantage of an .in file is the lack of a registered MIME type. Operating systems like Windows and macOS do not know what program to open it with, resulting in frustrating 'How do you want to open this file?' prompts. Furthermore, if you open a ColorNote .in backup in a text editor, you will only see corrupted gibberish because it is binary compressed data. To resolve these issues, you must convert the file based on its true internal format. For competitive programming or GoPro configs, convert .in to .TXT or .JSON for native readability in code editors. If it is a backup, convert the .in file to .ZIP to easily extract your notes. Drag and drop your file to analyze and convert it - free, online, and without installing software.

The IN Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our IN converter.
