Frequently Asked Questions

Base64 is an encoding scheme that converts binary data (like images) into ASCII text for embedding in HTML, CSS, or JSON.
Why does Base64 increase file size?
Base64 converts 3 bytes of binary data into 4 ASCII characters, resulting in approximately 33% larger output.
When should I use Base64 images?
Use Base64 for small images (icons, logos under 10KB), email templates, or single-file HTML documents.
Is my data secure?
Yes. All conversion happens entirely in your browser. No images are uploaded to any server.
