Encode and decode Base64 strings
How to Encode and Decode Base64
- Choose Operation: Select whether you want to encode (convert text to Base64) or decode (convert Base64 back to text) using the tabs.
- Enter Data: Paste your text or file data into the input field. For encoding, enter plain text. For decoding, enter valid Base64 string.
- Process and Copy: Click the Encode/Decode button to process your data, then use the Copy button to copy the result to your clipboard.
Frequently Asked Questions
What is Base64 encoding and when should I use it?
Base64 encoding converts binary data into a text format using 64 different ASCII characters. It's commonly used for encoding email attachments, embedding images in HTML/CSS, storing binary data in JSON, and transmitting data over text-based protocols.
Is Base64 encoding secure for passwords or sensitive data?
No, Base64 is not encryption and provides no security. It's a simple encoding scheme that can be easily decoded. Never use Base64 as a substitute for proper encryption when dealing with sensitive information.
Can I encode files with this tool?
Yes, this tool can encode and decode both text and files. For files, the Base64 output represents the binary file data as text, which is useful for embedding files in code or transmitting them over text-based protocols.
