What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that translates binary data (like images or files) into an ASCII string format. It is commonly used when there is a need to encode 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 transport.
How to Use This Tool
- Select Mode: Choose "Text" to type directly or "File" to upload an image or document.
- Choose Operation: Toggle between "Encode" (Text to Base64) or "Decode" (Base64 to Text).
- URL Safe Option: If you plan to use the output in a URL, check the "URL Safe" box. This replaces `+` with `-` and `/` with `_`.
- Copy or Download: Use the buttons in the top right of the result window to copy the output or download it as a file.
Why Use Client-Side Encoding?
Unlike many other online tools, DevTools Hub processes your data entirely within your web browser using JavaScript. This means:
- Your sensitive data (passwords, private keys, personal files) is never sent to our servers.
- Conversion is instant because there is no network latency.
- You can use this tool even when you are offline.
Common Use Cases
Embedding Images
Convert small images (icons, logos) to Base64 strings to embed them directly into HTML or CSS, reducing HTTP requests.
Data Transmission
Safely transmit binary data (like PDFs or archives) through JSON APIs or Email systems that only support text.
Is Base64 Encryption?
No. Base64 is an encoding scheme, not an encryption method. It is easily reversible and does not provide security. Do not use Base64 to hide sensitive data like passwords unless it is combined with actual encryption (like AES or RSA).
