Frequently Asked Questions

What is Base64 encoding used for?+

Base64 turns binary image data into plain text, letting you embed images directly inside HTML, CSS, JSON or emails without hosting a separate file.

When should I embed images as Base64?+

For small icons and logos where saving an HTTP request matters, in HTML emails, or in single-file documents. For large photos, normal image files are more efficient.

Why is the Base64 string larger than my file?+

Base64 encoding adds roughly 33% overhead because it represents every 3 bytes as 4 text characters. That's the trade-off for text-safe embedding.

Is my image uploaded anywhere?+

No — encoding is pure text transformation done locally in your browser. The image never leaves your device.
