The output and Before/After preview update automatically. Review highlighted markers for mappings that are lossy, ambiguous, or unsupported.
- Lossy: A sound is dropped or approximated, such as the Russian hard sign.
- Ambiguous: A Latin letter or sequence can map to more than one source letter. The tool uses a default mapping and flags the alternatives.
- Unsupported: A letter cannot be mapped in the selected direction.

Limitations and processing
Transliteration changes the writing system but does not translate meaning. Only the documented Russian, Latin, and Greek mappings are supported. Same-script selections and unsupported pairs show a warning instead of producing a result. When reverse conversion has several possible source letters for one Latin representation, the tool uses a default mapping and flags the alternatives. Conversion and file reading run in browser JavaScript.
Frequently Asked Questions
Does this tool translate meaning?
No. It changes the writing system only; it does not look up word meanings or translate languages.
Does it detect the source language or script automatically?
No. Select both the source and target scripts in From and To.
What do the highlighted (marked) letters in the preview mean?
Highlighted segments flag mappings that are not one-to-one. Lossy means a sound was dropped or approximated, such as the Russian hard sign. Ambiguous means a Latin letter or sequence could map to more than one source letter; the tool uses a default mapping and flags the alternatives. Unsupported means a letter cannot be mapped in the selected direction.
Are numbers, punctuation, and line breaks preserved?
Yes. Digits, punctuation, symbols, spaces, and line breaks pass through unchanged.
What files can I upload?
Upload accepts .txt and text/plain files. You can also drop a text file anywhere on the page.
Is my text sent to a server?
No. Conversion and file reading run in browser JavaScript without a server request.
