About Image → Data URI

Drag in an image and get a Base64 data URI you can paste straight into CSS or HTML — plus its file size, pixel dimensions, MIME type and the encoded length. Everything is read locally; the image is never uploaded.

What people use it for

Inline a small icon or logo as a data: URI to save an HTTP request.
Embed an image in an email template or single-file HTML page.
Check how much larger an image becomes once Base64-encoded.

Frequently asked questions

What formats work?

Any browser-readable image — PNG, JPEG, SVG, WebP and GIF.

How much bigger does Base64 make the file?

About a third larger — Base64 spends four characters on every three bytes, and the data: prefix adds a little more. Worth it for a small icon you want to inline; rarely worth it for a photo.

Is it private?

Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
