About Base64
What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used when you need to encode binary data for storage or transfer over text-based media.
Common Uses
- • Email attachments (MIME)
- • Data URIs in HTML/CSS
- • API authentication tokens
- • Storing complex data in JSON
- • Embedding images in code
About This Tool
Encode text to Base64 or decode Base64 back to readable text. Drop in a file and get its Base64 representation, or paste a Base64 string and see what it actually says. One of those tools you don't need often, but when you do, you really do.
How to Use
- 1Paste text or a Base64 string into the input field
- 2Click encode or decode
- 3Copy the result from the output field
- 4Optionally upload a file to get its Base64 encoding
Why Use This?
Base64 shows up everywhere — email attachments, API tokens, embedded images, data URIs. When you need to quickly encode or decode something, opening a terminal and remembering the right command is slower than just pasting it here.
