Frequently asked questions
When should I embed images as Base64?
For small images (icons, tiny logos) where saving an HTTP request matters. Large images are better served as normal files.
Why is the Base64 string larger than my file?
Base64 encoding adds roughly 33% overhead — that is normal and expected.
