Frequently Asked Questions
Why encode images as Base64?▾
Base64 data URIs let you embed images directly in HTML or CSS without separate HTTP requests, useful for small icons and inline graphics.
Does Base64 increase file size?▾
Yes, by about 33%. Base64 is best for small images (< 10 KB). Larger images should be served as regular files for performance.
What output formats are available?▾
The tool provides both a raw Base64 string and a complete data URI (data:image/PNG;base64,...) ready for use in code.
