Download AutoCodepage – Automatic Text File Encoding Detector and Converter

AutoCodepage is a lightweight utility for Windows that automatically detects and converts the character encoding of text files. It is especially useful for developers and content editors who work with files in multiple encodings such as UTF-8, ANSI, UTF-16, and various legacy code pages, helping eliminate garbled text and encoding mismatches across different systems.

The tool scans text files, identifies their current encoding, and converts them to the target encoding of your choice — all in batch mode. This makes AutoCodepage invaluable for projects that involve legacy data migration, internationalization work, or cross-platform file sharing where encoding consistency is critical.

AutoCodepage is portable and requires no installation. It integrates easily into batch scripts and automated workflows, making it a practical choice for developers, system administrators, and data processing teams who routinely handle text files in mixed encodings.
