The need for a simple encoding scheme that used only keys available on an ordinary keyboard was felt in the early days of the RMIM newsgroup where lyrics and trivia about Indian popular movie songs were being discussed. In parallel was a Sanskrit Mailing list that quickly felt the need of an exact and unambiguous encoding. ITRANS emerged on the RMIM newsgroup as early as 1994. This was spearheaded by Avinash Chopde, who developed a transliteration package. Its latest version is v5.34. The package also enables automatic conversion of the Roman script to the Indic version.
ITRANS was in use for the encoding of Indian etexts - it is wider in scope than the Harvard-Kyoto scheme for Devanagari transliteration, with which it coincides largely, but not entirely. The early Sanskrit mailing list of the early 1990s, almost same time as RMIM, developed into the full blown Sanskrit Documents project and now uses ITRANS extensively, with thousands of encoded texts. With the wider implementation of Unicode, the traditional IAST is used increasingly also for electronic texts.
ITRANS transliteration scheme
ITRANS transliteration scheme is given in the tables below. The ITRANS method is without using diacritics, as compared to other transliteration methods. While using ITRANS, for proper nouns, first letter capitalization is not possible since, ITRANS uses both capital and small letters in its lettering scheme.
|अं (added as anusvāra)||ਂ/ ੰ||అం||ಅಂ||ം||অং||M/N/.m|
|ऽ(avagraha:elision during sandhi)||ఽ||ಽ||ഽ||ঽ||.a|
|ॐ (Om symbol)||ఓం||ௐ||OM, AUM|
The Devanāgarī consonant letters include an implicit 'a' sound. In all of the transliteration systems, that 'a' sound must be represented explicitly.

- Aksharamukha transliteration tool. Akshara Mukha is an Asian script (two way) converter freeware. It converts between 20 different South Asian & East Asian scripts. It also supports 5 major Latin transliteration conventions such as IAST, ISO, Harvard Kyoto, ITRANS & Velthuis. You can access the project from here. While using the tool, 'source' can be set to for example: ITRANS or Harvard-Kyoto, and 'target' can be set to a particular script like Devanagari-Hindi.(When you are using a north Indian script, tick the box: Remove ‘a’.) It can work in reverse too, for example from Hindi to Latin by ISO transliteration.
