Frequently Asked Questions
What is Base64 encoding?
Base64 is a way to represent binary data (like images) as ASCII text. It's commonly used to embed images in HTML, CSS, or JSON without separate file requests.
When should I use Base64 images?
Use Base64 for small images (icons, logos under 10KB), email templates, or when you need to embed images in code. For larger images, regular files are more efficient.
Why is my Base64 string so long?
Base64 encoding increases data size by approximately 33%. A 10KB image becomes about 13KB when Base64 encoded. This is normal and expected.
