Frequently asked questions
When should I embed images as Base64?
For tiny icons or emails where an extra request is a problem. Larger images are better served as files.
Why is the Base64 bigger than the file?
Base64 encodes every 3 bytes as 4 characters, so it is about 33% larger.
Can I convert Base64 back to an image?
Yes. Switch to Base64 → Image and paste the string or data URI.
