What is Base64?
A binary-to-text encoding scheme representing binary data using 64 printable ASCII characters.
Common Uses
Email attachments, embedding images in HTML/CSS, API authentication tokens, and data URLs.
File Support
Upload any file to get its Base64 data URL — useful for embedding images inline in code.
What is a Base64 Tool?
A Base64 Tool encodes any text or file into Base64 format, or decodes Base64 strings back to their original content. Base64 is a binary-to-text encoding scheme that makes binary data safe for transmission in text-based protocols like HTTP headers, JSON, and email.
How to Use It
- 1Switch between 'Encode' and 'Decode' mode using the toggle
- 2Paste your text or Base64 string into the input field
- 3Or upload any file to encode it to Base64
- 4The output appears instantly — use the copy button to copy the result
Example
Encoding the text 'Hello, India!' → 'SGVsbG8sIEluZGlhIQ=='. Decoding 'SGVsbG8sIEluZGlhIQ==' → 'Hello, India!'. The = padding at the end is normal for Base64.
Why Use It
- Embed images directly in HTML or CSS as data URIs to reduce HTTP requests
- Encode JWT tokens and API credentials for safe URL transmission
- Transfer binary files through text-only channels like JSON APIs
- Debug base64-encoded data in HTTP requests or config files
