Base64 Encode / Decode

Encode text or files to Base64 and decode them back. Supports UTF-8 text and data URLs, with instant conversion as you type — privately, in your browser.

Examples

How it works

Encode turns your text into UTF-8 bytes and writes those bytes in the 64-character Base64 alphabet. Decode does the reverse and reads the bytes back as UTF-8, so accents, emoji and non-Latin scripts survive the round trip.

Three bytes become four characters; “=” pads the last group
Text	Base64
A	QQ==
AB	QUI=
ABC	QUJD

Base64 output is about a third longer than the input. Spaces and line breaks in pasted Base64 are ignored when decoding. The URL-safe variant, which uses - and _ in place of + and /, has to be changed back to + and / first. Base64 is an encoding, not encryption: anyone can decode it.

Frequently asked questions

Does it support Unicode?

Yes. Encoding is UTF-8 safe, so emoji and non-Latin scripts round-trip correctly.

Can I decode a data URL?

Yes — paste the full data URL and switch to Decode to extract the payload.
