Aksharamukha aims to provide script conversion between various scripts within the Indic cultural sphere (South Asia, Central Asia, South East Asia, East Asia). These include historic scripts, contemporary Brahmi-derived/inspired scripts, scripts invented for minority Indian languages, scripts that have co-existed with Indic scripts (like Avestan) or linguistically related scripts like Old Persian. It also specifically provides lossless transliteration between the main Indian scripts (along with Sinhala).

Apart from the simple mapping of characters, Aksharamukha also attempts to implement various script/language-specific orthographic conventions (where known) such as vowel lengths, gemination and nasalization. It also provides several customization options to fine-tune and get the desired orthography.
