FAQ

What do I need Base64 for?

Base64 allows embedding images directly in HTML, CSS, or JSON without requiring separate image files.

What's the difference between 'Complete' and 'Data Only'?

'Complete' contains the Data-URL (data:image/png;base64,...). 'Data Only' contains just the Base64 string without prefix.

Are large images supported?

Yes, but Base64 increases file size by ~33%. For large images, separate files are often better.
