What is Base64?
Base64 is an encoding that turns binary data or text into an ASCII string (A-Z, a-z, 0-9, + and /). It is used to carry data in text-only contexts: emails, URLs, embedding images in CSS/HTML (data URI), tokens, and more.
Encode or decode in one click
Type your text and click Encode; or paste a Base64 string and click Decode. Our tool handles UTF-8, so accents and emojis are converted correctly.
Frequently asked questions
Does Base64 encrypt my data?
No. Base64 is an encoding, not encryption: anyone can decode it. Never use it to protect sensitive information.
Are accents supported?
Yes, the tool encodes in UTF-8, so é, à, ü, emojis… are fully supported.
Is my data sent to a server?
No, all processing happens in your browser.
