❓ Frequently Asked Questions
What is Base64 encoding?
Base64 is a method to encode binary data (like images) into ASCII text. This allows images to be embedded directly in HTML, CSS, or JSON without separate file requests.
When should I use Base64 images?
Use Base64 for small images (icons, logos under 10KB), inline SVGs, or when you need to embed images in CSS/JSON. Avoid for large images as it increases file size by ~33%.
What is a Data URI?
A Data URI is a Base64 string with a MIME type prefix (data:image/png;base64,...). It can be used directly in HTML src or CSS url() properties.
Are my images uploaded to a server?
No! All conversion happens in your browser using JavaScript. Your images never leave your device, ensuring complete privacy.
