About EtheLab Base64 Encoder/Decoder
The **Online Base64 Encoder, Decoder & Converter** is a double-utility web application designed for processing strings and binary file formats. Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format, commonly used to embed images in HTML documents or transfer binary payloads over textual APIs.
How to Convert Text to Base64:
- Ensure the **Text Converter** tab is selected, and choose **Encode** mode.
- Paste your raw text (e.g., config settings, HTML snippets, API payloads) in the input pane.
- Copy the resulting Base64 string from the output pane instantly. Toggle **Decode** mode to reverse the operation.
File-to-Base64 Conversion & Visual Decoding
Secure Binary Processing: Skip the security risks of uploading files to servers. Our **Image & File Tool** runs 100% inside your browser sandbox. Drag and drop any image, vector SVG, text document, or PDF file to generate its raw Base64 data string or complete Data URL template (ideal for ` src` tags).
Decode base64 to File: Paste any base64 string or Data URL on the left. The tool automatically extracts the MIME type and file extension, displays a visual thumbnail or preview, and allows you to download the file back to your system as a binary payload.
