Frequently Asked Questions
What is Base64 image encoding used for?
Base64 image encoding embeds images directly into HTML, CSS, or JavaScript as text strings, eliminating extra HTTP requests. It's commonly used for small icons, email templates, and offline apps.
Does my image get uploaded to a server?
No. This tool uses the FileReader API to process your image entirely in your browser. Your image data never leaves your device.
Why is the Base64 output larger than the original image?
Base64 encoding increases file size by approximately 33% because it represents binary data using only printable ASCII characters, requiring more characters to encode the same information.
What image formats are supported?
PNG, JPG/JPEG, GIF, WebP, SVG, and most other browser-supported image formats are supported.
