Runs in your browser — your files and text stay on your device
Convert an image into a Base64 data URL you can embed directly in HTML, CSS or JSON. Inlining works best for small images such as icons, because Base64 makes the data about a third larger. The image is encoded in your browser and never uploaded.

Frequently asked questions
What is a Base64 data URL used for?
It embeds an image directly inside HTML, CSS, or JSON as text, avoiding a separate file request — useful for small icons or inlining assets.
Is my image uploaded anywhere?
No — this uses your browser's built-in FileReader API and happens entirely locally.
