Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used to embed images directly in HTML, CSS, or JSON files.
What is a data URI?
A data URI is a scheme that allows you to include inline data in web pages as if they were external resources. For images, it looks like data:image/png;base64,... and can be used directly in src attributes.
When should I use Base64 images?
Base64 images are useful for small icons, reducing HTTP requests, embedding in emails, or when you want a self-contained HTML file. For larger images, regular files are usually better.
Does Base64 encoding increase file size?
Yes, Base64 encoding typically increases the file size by about 33% compared to the original binary. This is a trade-off for the convenience of inline embedding.
What image formats are supported?
PicKit supports converting JPG, PNG, WebP, and GIF images to Base64. The output includes the correct MIME type for each format.
