About Image to Base64
This converter turns an image into a Base64 data URI you can paste directly into HTML, CSS, or JSON. It suits front-end developers inlining small icons, email designers embedding images without external hosting, and anyone who needs an image as text.
Inlining an image as a data URI removes a separate HTTP request and keeps the asset self-contained. Doing it in the browser means the image — which may be unreleased or private — is never uploaded anywhere.
Step by step
- Drag an image onto the drop zone, or click to choose a file from your device.
- A preview appears so you can confirm you selected the right image.
- The encoded data URI is generated automatically below the preview.
- Choose whether you want the raw Base64 or a full data: URI with the MIME prefix.
- Copy the result, or download it as a text file to drop into your project.
What it offers
- Drop, browse, or paste input
- Base64 and data-URI output
- Ready-to-use snippets
- Encoded on your device
Tips for best results
- Inline only small images — data URIs add roughly a third to the original size and bloat HTML if overused.
- For icons used across many pages, a sprite or icon font is usually lighter than repeated data URIs.
- Keep large photos as normal linked files; data URIs are best for tiny, frequently-inlined assets.
Why people use it
No hosting needed
Embed the image directly in markup instead of uploading it somewhere first.
Fully private
Encoding happens on your device; the image is never sent to a server.
Correct MIME
The data URI is built with the right media type so it renders everywhere.
Copy or download
Take the result as clipboard text or a saved file, whichever fits your workflow.
Common questions
This runs entirely in your browser
No file or text you enter here is uploaded. Encoding and decoding happen on your device using native browser APIs — close the tab and nothing remains on a server.
