ASCII Converter

The ASCII Converter shows the ASCII codes for text, decodes codes back to text, and includes a reference table of printable characters. It is for developers and students working with character codes.

Looking up ASCII values one by one is tedious. Converting in bulk locally is instant, and the included table saves a separate lookup.

1. Type or paste text to see its ASCII codes, or paste codes to decode.
2. The conversion updates live in both directions.
3. Use the reference table to look up individual printable characters.
4. Copy the codes or decoded text you need.

• Text-to-ASCII and ASCII-to-text conversion
• Reference table of printable characters
• Live two-way conversion
• Converted in the browser

• Decoding a list of character codes from a data file
• Looking up the code for a specific character
• Teaching how text maps to numeric codes
• Debugging output that shows raw character values

• Remember standard ASCII covers 0–127; higher values belong to extended sets or UTF-8.
• Keep decimal and hexadecimal codes clearly separated to avoid misreading them.
• Use the reference table to confirm a control character rather than guessing.

• Treating values above 127 as ASCII; standard ASCII only defines 0–127, and beyond that depends on the encoding.
• Mixing decimal and hexadecimal codes without noticing, which decodes to the wrong characters.
• Forgetting that control characters below 32 are non-printing and will not show visibly.
