Encode Images to Base64 Data URIs

Turn PNG, JPG, or WEBP files into Base64 strings for HTML img src, CSS background-data URIs, JSON payloads, and email templates. Copy the exact string your stack expects without terminal base64 commands.

Data URIs inline small assets to cut HTTP requests—useful for icons and thumbnails when caching strategy allows. For large photos, prefer normal URLs to avoid bloating HTML.

Encoding happens in your browser from files you select; nothing is uploaded to a server for conversion.

Developer-friendly

Drop an image, copy Base64, paste into code or API bodies.

Instant

No CLI—great for quick experiments and prototypes.

Stay local

Client-side encoding keeps assets off shared servers.

MIME aware

Output matches image type for correct data URI headers.
