ASCII (American Standard Code for Information Interchange) assigns numbers 0–127 to letters, digits, punctuation and control characters. Every ASCII character is one byte, and UTF-8 encodes these 128 characters exactly the same way, so this table is the starting point for encoding Base64 by hand.

The last column shows what a single byte with that value looks like in Base64. Notice that one byte always produces two characters plus ==.

Characters 0–31 and 127 are non-printable control codes. The most common ones are HT (tab, 9), LF (line feed, 10) and CR (carriage return, 13). Values 128–255 are not ASCII; their meaning depends on the character set (for example Windows-1252 or ISO-8859-1), and in UTF-8 they only appear as parts of multi-byte characters.

الأسئلة الشائعة

Does this page upload my data?

No. Articles are static. Linked tools run locally in your browser unless a feature explicitly needs a network relay.

Can I request a translation or a new tool?

Yes — use the private feedback form. We prioritize what users ask for across languages.

What is the fastest way to try ascii table?

Open the homepage Base64 converter or the related tools linked on this page and paste a sample.
