About Base64 Encoding & Decoding
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is widely used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with textual data. This ensures that the data remains intact without modification during transit.
How to use the Online Base64 Tool
1. Select Mode: Choose between Encode to convert plain text/files to Base64, or Decode to convert Base64 strings back to their original text or binary files.
2. Input Text or File: Type/paste your text into the left editor panel. Alternatively, drag and drop any file (like images, documents, or keys) to compute locally.
3. Copy or Download: Instantly copy the output to your clipboard or download it as a file.
Is Base64 secure?
No. Base64 is NOT encryption. It is merely a representation format. Anyone can easily decode a Base64 string back to its original bytes. Never use Base64 to secure sensitive data unless it is first encrypted with a cryptographic algorithm like AES.
