Base64 Tool
Encode and decode binary data.
Understanding Base64 Encoding & Decoding
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is designed to allow data to be safely transmitted over media that are designed to deal with textual data, such as email attachments or HTML URLs.
Oyaam's Base64 Tool provides rapid, bidirectional encoding and decoding directly in your web browser. This ensures that sensitive strings, API credentials, or code snippets are processed securely on your local device without being transmitted to external servers.
Common Use Cases
- Data Embedding: Convert small icons or assets into Data URLs for inline inclusion in HTML or CSS stylesheets.
- API Transports: Safely encode binary data or complex headers for transit over standard JSON web services.
- JWT Inspection: Prepare token signatures and payloads for decoding and analysis.
How to use Base64
- Enter your plain text or paste a Base64-encoded string into the editor.
- Click "Encode" to convert raw text to Base64, or click "Decode" to restore text from its encoded form.
- Copy the resulting string immediately from the output box.
