Why Convert Images to Base64?

Frequently Asked Questions

Is my image uploaded anywhere?
No. The conversion happens entirely in your browser using the FileReader API. Your image never leaves your device.
What is the difference between a data URL and base64?
A data URL is the full string including the prefix (data:image/png;base64,...). Base64 is just the encoded data after the comma. Use the data URL directly in HTML/CSS, and the bare base64 for APIs or JSON payloads.
What image formats are supported?
Any image format your browser can display: PNG, JPEG, GIF, WebP, SVG, BMP, and more.
