About this tool
Convert text to Base64 and back with full Unicode (UTF-8) support. Base64 is widely used to embed binary data in text formats such as data URIs, email and JSON. The conversion is local and instant.
Frequently asked questions
Does it handle emoji and non-Latin text?
Yes. Text is encoded as UTF-8 first, so emoji, accents and any Unicode characters round-trip correctly.
Can I decode a Base64 data URI?
Paste just the Base64 part (after the comma) to decode it. The tool expects raw Base64.
