Frequently Asked Questions
What is Base64 encoding used for?
Base64 encoding is primarily used to represent binary data (like images or files) in an ASCII string format. This allows binary data to be transmitted over media that are designed to handle text, such as email (MIME) or JSON data.
Is ToolPix Base64 Encoder secure?
Yes, ToolPix processes all data locally in your browser using JavaScript. No data is sent to our servers, ensuring your text, files, and images remain private and secure.
Can I convert images to Base64 strings?
Yes, our tool supports converting images (JPG, PNG, GIF, SVG) directly into Base64 strings, which can be used in HTML img tags or CSS data URIs.
How do I decode a Base64 string?
Simply switch the tool to 'Decode' mode, paste your Base64 string into the input area, and the tool will instantly convert it back to its original text or file format.
Does this tool support UTF-8 characters and emojis?
Absolutely. Our encoder handles UTF-8 characters and emojis correctly, ensuring that special characters are encoded and decoded without corruption.
