Base64 turns text into a safe ASCII string for transport, and back again. This page does both: base64 encode and base64 decode in your browser, free, with full UTF-8 support so nothing gets mangled. As a base64 converter it keeps your text on your device.
Both directions, one click each.
To go from plain text to an encoded string, paste your text and encode. That is the whole of text to base64, and people also search for it as base 64 encode online, base64 encode online, or convert to base64 online. The reverse is just as quick: paste an encoded value and run base64 decode online, sometimes typed as decode 64, to get the original text.
Both directions are UTF-8 safe, which matters more than it sounds. Emoji, accented characters, and non-Latin scripts all survive the round trip instead of turning into garbled bytes.
Decoding is not decryption.
Decoding gives you base64 to text directly, so the tool works as a base64 to text converter. One thing worth clearing up: Base64 is an encoding, not a cipher. Searches for base64 decrypt usually just mean decode, since there is no key and no security involved, only a reversible transformation.
No need to bounce between pages.
A lot of sites split encoding and decoding into separate tools. Here they sit together, so a single base64 converter covers both. Whether you think of it as an encoder and decoder online, an encode decode online utility, or a base64decoder, it is the same page. The combined base64 encode decode flow, or base64 encode and decode if you prefer the longer phrasing, saves a tab switch every time.
Where text encoding stops.
This page handles text. It is not built for base64 decode to file, base64 to file online, or base64 decode image online, since those rebuild binary data and need a download step. For those, use a file-oriented Base64 tool instead.
One common case does fit, though: when the decoded text is JSON, as it often is inside tokens and configs. Decode it here, then for base64 to json paste the result into the JSON Formatter to indent and validate it.
