Frequently Asked Questions
Why would I embed images as Base64?
Base64 embedding eliminates extra HTTP requests, which can improve load times for small images like icons, logos, and sprites. It's also useful for embedding images in JSON APIs, emails, and single-file HTML documents.
Is there a size limit?
There's no hard limit, but Base64 encoding increases file size by ~33%. Images larger than 10KB are generally better served as separate files. Base64 is best for small icons and thumbnails.
Which output formats are available?
RAW provides three output formats: full data URI (for HTML img src), raw Base64 string (for API payloads), and CSS background-image snippet (for stylesheets).
