Unicode to Devlys only works if you name the right font
An old office template still prints Hindi only when the font is Devlys.
Unicode Hindi is mapped back to Devlys characters in the browser. You must then set the Devlys font, or the letters will look wrong.
If the Hindi comes out scrambled
Keep the Unicode copy. The Devlys text is not safe to paste into a website. The wrong source font produces the wrong words.
The other Hindi font tools are on the font tools page.
When Unicode to Devlys is the right page
Unicode to Devlys sits on this site because Unicode and Devlys are not interchangeable, even when they look similar in a file list. An old office template still prints Hindi only when the font is Devlys. Websites, phones, and current Word need Unicode, not a legacy font encoding. Old templates that print correctly only in Devlys need a conversion before they can go on the web.

What you give up by leaving Unicode
Unicode Hindi is the text you get from Google and modern Windows. The letters are real Hindi characters. Running Unicode through a Kruti Dev or Devlys converter scrambles real Hindi.
Keep a Unicode copy. Legacy-font text is not safe to paste on the web.
What you gain, and do not gain, with Devlys
The download has to be Devlys, because that is the format the next step named. Old templates that print correctly only in Devlys need a conversion before they can go on the web. Devlys can be mapped to Unicode, and Unicode can be mapped back for those old templates.
Test one sentence. The wrong source font produces the wrong words.
A test that matches the real file
Start from the question the other software asked. If it asked for Devlys, Unicode to Devlys is the matching page. If it asked for something else, switch tools instead of hoping a similar extension will pass. An old office template still prints Hindi only when the font is Devlys. Unicode Hindi is mapped back to Devlys characters in the browser. You must then set the Devlys font, or the letters will look wrong. The limit is the part people skip, and it is the part that decides whether the download is usable. Keep the Unicode copy. The Devlys text is not safe to paste into a website. The wrong source font produces the wrong words. The text stays in the browser. Try one line you can check before a whole document. Do not paste passwords. Check three things in the download: it opens, the Unicode material you cared about is still there, and the file size or the layout is what the form described. A new extension alone is not those three things. If a portal, a teacher, or a client rejects the file, send them the original Unicode as well when you are allowed to. Unicode to Devlys is a convenience copy. It is not a new master. Legacy Hindi fonts are not Unicode. Unicode to Devlys only works if you name the font the text was actually typed in. The wrong mapping produces words that look like Hindi and say something else. Convert one sentence you can read, compare it, then do the rest. Keep a copy of the original document.
Here is the decision for Unicode to Devlys. You start with Unicode and you stop when a real program accepts Devlys. Once text is Unicode, any normal Hindi font can display it, including Mangal. You must then set the Devlys font, or the legacy letters look wrong. Unicode text run the wrong way will scramble. If those two sentences describe a tradeoff you do not want, do not convert. Renaming the extension by hand will not do this job. Running the tool twice on its own output will not do it either.

A related step, if you still need one, is Devlys to Unicode.
Other jobs start from the homepage, where each tool is named for the conversion it actually does.
