What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used to embed binary data in text-based formats like emails, URLs, and JSON. Our tool allows you to both encode text to Base64 and decode Base64 back to its original text.
How to use our Base64 Encoder/Decoder
- Select whether you want to "Encode" or "Decode".
- Paste your text or Base64 string into the input field.
- Alternatively, you can upload a file to be processed.
- Choose your desired options, such as URL-safe encoding or line splitting.
- The result will appear in the output field. You can then copy it or download it as a file.

Frequently Asked Questions (FAQ)
Is my data secure?
Yes, all processing is done on the client-side in your browser. No data is ever sent to our servers.
What is the difference between standard and URL-safe Base64?
URL-safe Base64 replaces the "+" and "/" characters with "-" and "_" respectively, making it safe to use in URLs without being misinterpreted.
Can I encode images or other files with this tool?
Yes, you can upload any file, and our tool will automatically encode it to a Base64 string.
