Frequently Asked Questions
What is Base64 encoding for images?
Base64 encoding converts binary image data into a text string made up of ASCII characters. This allows images to be embedded directly into HTML, CSS, or JSON without needing a separate file request.
When should I use Base64-encoded images?
Base64 images are useful for embedding small icons, logos, or thumbnails directly in HTML or CSS to reduce HTTP requests. They are also handy for sending image data through APIs or storing images in databases as text.
Are my images uploaded to a server?
No. All conversion happens entirely in your browser using the JavaScript FileReader API. Your images never leave your device and are never sent to any server.
What is the difference between Data URI and Raw Base64?
A Data URI includes the full prefix (e.g., data:image/png;base64,...) and can be used directly as an image src attribute in HTML or in CSS. Raw Base64 is just the encoded string without the prefix, useful when you need to send the data to an API or store it separately.
Does Base64 increase the file size?
Yes. Base64 encoding increases the data size by approximately 33% compared to the original binary. This is why it is best suited for small images rather than large photographs.
