When you need Senthamizh output
Senthamizh is a legacy Tamil font format used in some older publishing workflows. Unicode is the right format for almost everything today, but occasionally a printer, an old layout file or a colleague insists on Senthamizh. Paste your Unicode Tamil here and the page produces the Senthamizh version.
The converted text is not meant to look like Tamil on its own
Because this format uses private-use characters rather than readable Latin letters, there is no tidy string to quote here. Senthamizh output is stored in private-use code points; தமிழ் is three of them. Those characters only look like Tamil in the matching font, so check the result in the application that actually needs it rather than in a plain editor. Without the matching font the result will not look like Tamil, which is normal for this kind of format and not a fault in the conversion.
How to use the converter
Copy the Unicode text, paste it in, convert, and then copy the Senthamizh result. The best test is to paste a small piece into the real destination and apply the correct font there before converting the whole document.
Testing in the destination
Do not judge the result in a plain editor. Open the application that will receive it, apply the right font, and look at names, numbers and conjunct letters. If the destination expects a slightly different format, a letter or two will come out wrong.
Who tends to need this
People usually need legacy output for a specific reason: a print shop with an older layout setup, a publication that still works in a font-based pipeline, or a recipient who cannot open Unicode files. If that is not you, keep working in Unicode and skip this step. Convert only when something downstream really asks for Senthamizh.
Small habits that save time
Work from the original text whenever you can, not from a screenshot or a re-typed copy. Convert a short sample first and keep the original file untouched. If a document mixes several fonts, convert each section with its own tool. Clear both boxes before pasting something new so that old text does not sneak into the next job.
Do not throw away the original
Once you have the Senthamizh output, save it under a separate name. Keep editing the Unicode text instead, then convert again when you need an updated legacy file. That way you never lose the clean version.

Unicode to Senthamizh: common questions
Why does Senthamizh output look blank in some programs?
Private-use characters have no standard appearance. Without the matching font they appear as boxes, question marks or nothing at all.
Should I keep the Senthamizh copy?
Keep it only if you need it for the older workflow. Your Unicode text is the one to edit, search and share.
Can I convert a Word file or PDF directly?
This is a paste-in tool, so there is no file upload. Copy the text out of the document, paste it in, then copy or download the result. A PDF has to contain real selectable text; scanned pages need OCR first.
Will the conversion change what my text says?
No. Only the way the characters are stored changes, not the language or the wording. Even so, read names, numbers and punctuation once after converting.
Is my text uploaded anywhere?
No. The conversion runs in your browser on this page, so the text you paste is processed on your own device. It is still sensible to avoid pasting anything confidential on a shared computer.
Why does my converted text still look wrong?
Check three things in order: that you chose the format that matches the original, that the text was copied rather than retyped, and that the direction of the tool (legacy to Unicode or the reverse) is the one you meant.
Is it free, and do I need an account?
It is free and there is no sign-up. Paste your text, convert it, then copy it or download it as a .txt file.
