How to use Convert Alt Code to Unicode
- 1. Paste your Alt codes. Enter one or more Windows Alt codes such as 'Alt+0233' or 'Alt+130', separated by spaces, exactly as you would type them while holding the Alt key on a numeric keypad.
- 2. Let the tool resolve each code. The converter maps each Alt code through the CP1252 or CP437 code page depending on its format, since Windows Alt codes rely on legacy code pages rather than raw Unicode values.
- 3. Review the resulting glyphs. Check the output pane for the actual characters, such as accented letters or symbols, that each Alt code produces.
- 4. Copy the decoded characters. Copy the resulting text into a document, chat message or design file wherever you need the character an Alt code was meant to produce.
When to use Convert Alt Code to Unicode
Convert Alt Code to Unicode decodes Windows numeric Alt codes into the actual characters they represent, useful whenever you have a list of Alt codes but no numeric keypad handy. It resolves both CP1252 and CP437 style codes into readable Unicode glyphs.
- Reproducing an old keyboard shortcut list. A shared document lists Alt codes for special characters like accented letters, but you are on a laptop without a numeric keypad. Converting the codes gives you the actual glyphs to copy.
- Understanding a legacy Windows macro. An old AutoHotkey script or macro types characters using Alt+numpad sequences. Decoding those codes tells you exactly what text the macro was designed to insert.
- Recovering box-drawing symbols from CP437 codes. A retro terminal or DOS-era document references Alt codes for line and block characters. Converting them reveals the CP437 box-drawing glyphs they correspond to.
- Teaching Alt code shortcuts. You are writing a reference guide on typing accented characters with Alt codes and want to verify each code resolves to the letter you expect before publishing the list.

About the Convert Alt Code to Unicode tool
Convert Alt Code to Unicode runs as plain JavaScript in your browser tab, with no server behind it. Generate Unicode glyphs from Alt codes. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Unicode Tools section, 98 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. A worked example further down the page shows exactly what the tool produces for a real input.
