Text to ASCII Converter
Convert text to ASCII codes or decode ASCII codes back to text. See decimal values for every character instantly.
About the Text to ASCII Converter
This text to ascii converter represents each Unicode code point as a base-10 number. For example, A😀 becomes 65 128512. Type text in the Text box to encode it. Click Swap to make the input accept codes, then paste numbers separated by spaces, commas or line breaks. The direction is explicit so ordinary text such as 123 is encoded as three characters. ASCII characters use their familiar values; emoji use one complete code point rather than two surrogate values. These are code points, not UTF-8 bytes.
Features
- Text to ASCII / Unicode decimal code points
- Decode valid base-10 code points back to text
- Explicit conversion direction with Swap
- Editable text and code boxes
- Complete Unicode code points, including emoji
- Validation for invalid codes and surrogate values
How to use this tool
The Text to ASCII Converter works right in your browser — no signup, no installation. Follow these steps:
- Enter text in the Text box to encode it.
- To decode, click Swap and enter codes in the box labelled codes.
- Separate codes with spaces, commas or line breaks.
- Review the result or any validation message, then copy it.
Frequently asked questions
How do I switch between encoding and decoding?
Click Swap to exchange the box contents and reverse their roles. The labels show which box accepts text and which accepts codes. You can also edit the code box directly.
What happens to emoji and non-ASCII characters?
Each is represented by its Unicode code point in base 10. A😀 becomes 65 128512. Values above 127 are outside standard ASCII.
Is the output a sequence of UTF-8 bytes?
No. A code point identifies a character; UTF-8 encodes that value into one or more bytes. Use a byte encoder when a file format or protocol requires UTF-8.
Using the results
Use the Text to ASCII Converter to transform supported text or data formats in your browser. Review the output before replacing your original, since some conversions change formatting or discard information.
