What is Base64 encoding typically used for images and text?

For images, Base64 encoding is used to create Data URIs for embedding directly in HTML/CSS, reducing HTTP requests. The 'image to base64' function is key here. For text, it's used to safely transmit or store data that might otherwise be misinterpreted (e.g., special characters in JSON/XML, or binary data represented as strings). Both image to base64 and text to base64 are common operations.

Is Base64 encoding a form of encryption?

No, Base64 is an encoding scheme, not an encryption method. It's easily reversible (decode from base64). While it makes data unreadable at a glance, it provides no real security. Do not use it as a base64 encryption tool for sensitive information.

Can I convert any file to Base64 with this online tool?

This tool is optimized for 'image to Base64' (as Data URI using our base64 image encoder) and text to Base64. While you could theoretically convert a file to a string and then to Base64 using the text tab, for direct base64 file encoder/decoder functionality for generic files, specialized tools might be more appropriate.

How does the 'Base64 to Image' functionality work?

When you provide a Base64 string (preferably a full Data URI like 'data:image/png;base64,...'), the 'Base64 to Image' feature (our base 64 to image decoder) decodes the string back to its binary image data and attempts to render it. If you provide only the raw Base64 data, it tries to guess the MIME type, defaulting to PNG if unsure.

Does this tool support Base64 URL encoding/decoding?

Standard Base64 includes characters '+' and '/' which are not URL-safe. Base64URL encoding replaces these with '-' and '_' and removes padding. While this tool primarily handles standard Base64, for simple cases without padding or those specific characters, it might work. For true Base64URL needs, a dedicated tool is recommended.
