About Text to ASCII Codes Converter
Convert text to ASCII codes as you type, or paste ASCII codes to turn it back into text — the direction is detected for you. Text is encoded as UTF-8, so accents, Indian scripts and emoji work.
Choose the separator, padding and prefixes, switch to Unicode code points, or use the other encodings: binary, hex, decimal, octal, Base64, URL encoding, HTML entities and \u escapes. Download the result or a per-character table with every format.
Good for
- Programming, debugging and data exchange
- Computer science lessons and puzzles
- Checking how characters are stored
Tip: Paste the code straight in — spaces, commas, 0x and \x prefixes are all understood when decoding.
Frequently asked questions
What is an ASCII code?
A number from 0 to 127 for each basic character — A is 65, a is 97, space is 32 and 0 is 48. Characters beyond ASCII (é, ₹, emoji) use Unicode code points or UTF-8 bytes.
Can it convert ASCII codes back to text?
Yes — paste the numbers separated by spaces or commas and they are decoded to text automatically.
Can I get the codes in hex, binary or octal?
Yes — switch the code to Hexadecimal, Binary or Octal, or download the character table with every format for each character.
Which other encodings are included?
Binary, hexadecimal, decimal / ASCII, octal, Base64 (also URL-safe and MIME-wrapped), URL encoding, HTML entities and Unicode escapes — each in both directions.
Can I convert a file?
Yes — open or drop a text file (TXT, CSV, JSON, Markdown, Word or PDF); it is read in your browser.
Is my text uploaded?
No — the conversion runs entirely in your browser, so private text, keys and files never leave your device.
