Base64 Encoder/Decoder
Encode and decode text or binary data in Base64 format for embedding images, APIs, and data transfer
How to Use This Tool
Choose Encode or Decode mode, then Text or File tab.
In Text mode, type or paste — output updates in real time.
In File mode, upload to encode/decode. Auto-detection suggests decoding when input looks like Base64.
About This Tool
Base64 Encoder/Decoder converts between text/binary files and Base64 encoding. Commonly used for embedding images in HTML/CSS, transmitting binary data over text protocols, and storing binary data in databases.
Frequently Asked Questions
Embedding images in HTML (data URIs), transmitting binary in JSON APIs, encoding email attachments, and storing binary in text-only databases.
No. Base64 is encoding, not encryption. It's easily reversible and provides no security.
