What this SunTommy to Unicode converter is for
SunTommy is a legacy Tamil format that you may see in older documents prepared on desktop publishing setups. The trouble is that SunTommy text only looks like Tamil while the right font is in place. This page reads the stored characters and writes them back as ordinary Unicode Tamil, which any modern app can display, search and spell-check.
What SunTommy text looks like when the font is missing
Open the file in a plain editor or paste a few words into a blank page with an ordinary font. If the Tamil turns into Latin letters, symbols and punctuation, you are looking at font-encoded text. To give you something concrete, this converter stores தமிழ் in SunTommy as jkpo;, வணக்கம் as tzf;fk; and நன்றி as ed;wp. For our sample words SunTommy produced the same characters as Bamini, for example jkpo; for தமிழ். Do not rely on that for everything. Rare letters and symbols are where formats drift apart, so spot-check them.
How to use the converter
Copy a short passage from the source, paste it into the input and convert it. Once the sample reads correctly, convert the rest. Copy the result straight into Word, an email or a website, or save it with the download button.
Checking the result
Skim the output slowly the first time. Names, dates, numerals and conjunct letters are where small differences hide. If a single word looks wrong, convert it on its own to find out whether the original file was damaged or whether a neighbouring format is a better match.
Typical situations
Most visitors arrive with a folder of old Tamil work. It might be typed notes, a newsletter, a community record or a draft that must be edited again. Converting it to Unicode lets you reuse the writing instead of retyping it from scratch, which is slow and invites new mistakes.
Tips for cleaner results
Keep the source file safe and work on a copy. Paste in plain text where possible, and avoid copying from places that quietly change characters, such as some PDF viewers. When a passage mixes formats, split it up and treat each part separately. Press Clear between jobs so the boxes start fresh.
The benefit of having Unicode Tamil
Once the text is Unicode, you no longer depend on SunTommy being installed. You can search inside it, sort it, spell-check it, paste it into messaging apps and publish it on the web, and it will display the same way on phones, laptops and servers. Keep the Unicode copy as your master and treat the old SunTommy file as an archive.

SunTommy to Unicode: common questions
SunTommy and Bamini gave me the same result. Can I use either?
For common words the codes matched, so the output often will too. For anything important, use the converter that matches the file and review unusual letters.
Why do some words convert and others come out wrong?
Usually a rare letter, a conjunct such as க்ஷ, or a symbol that the source handled differently. Isolate the word and test it alone.
Can I upload a document?
Not here. You paste text into the box and download the output as a plain .txt file if you want to keep it. For Word or PDF files, copy the text out first.
Does converting alter the meaning or spelling?
It should not. The tool changes the encoding, so the same words are stored a different way. Review it anyway, especially for names and unusual spellings.
Does the text I paste leave my computer?
The page does the conversion locally in your browser. Nothing you paste into the boxes needs to be sent anywhere for the converter to work.
The result has odd letters in it. What should I try?
Most often the format is not quite the one the file used, or a character changed when it was copied from a PDF or another program. Test a short, familiar line and compare it with the original.
Is there a limit on how much I can convert?
There is no account and no fee. Very long documents are easier to check if you convert them in manageable sections, so the review does not feel overwhelming.
