Frequently Asked Questions
What is Base64 image encoding?
Base64 image encoding converts an image file into a text string that can be embedded directly in HTML, CSS, or JavaScript. This eliminates the need for separate image files and HTTP requests.
What image formats are supported?
This tool supports PNG, JPG/JPEG, GIF, SVG, and WebP formats. The output preserves the original MIME type in the data URI prefix.
When should I embed images as Base64?
Base64 embedding is ideal for small images like icons, logos, and UI elements. It reduces HTTP requests and speeds up page loading. However, large images should remain as separate files for better caching.
How does Base64 affect file size?
Base64 encoding increases file size by approximately 33% compared to the original binary. This trade-off is usually worth it for small images since it eliminates a separate HTTP request.
