Image to Base64 Converter — Free Online Tool
Convert any image to a Base64 data URI instantly. Drag and drop an image, and get the full Base64-encoded string ready to embed in HTML, CSS, or JSON. No upload to any server — all processing is done locally in your browser.
Use cases
Base64 encoding is ideal for embedding small images directly into HTML <img> tags, CSS backgrounds, JSON data, or email templates. It eliminates the need for separate image file hosting for icons, logos, and thumbnails.
Privacy & security
This is a privacy-first tool. Your image is never uploaded anywhere — the conversion happens entirely on your device using the FileReader API. Sensitive or confidential images stay safe.
Tip
Base64 encoding increases file size by ~33%, so it is best suited for small images under 100KB. For larger images, consider our Image Compressor first.
