Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used for encoding data in URLs, email attachments, and embedding images in CSS or HTML.
Is Base64 encoding secure?
No. Base64 is an encoding scheme, not encryption. Anyone can decode Base64 data. Never use Base64 alone to protect sensitive information like passwords or API keys.
How do I convert an image to Base64?
Use the File Mode in our tool. Drag and drop your image file, and it will be converted to a Base64 Data URI that you can embed directly in HTML or CSS.
