Guide
How to convert an image to Base64
1
Select Your Image
Drag and drop an image or click to choose one. PNG, JPG, GIF, SVG, WebP, and more all work.
2
Pick an Output Format
Choose a plain data URI, raw Base64, or a ready CSS, HTML, or Markdown snippet.
3
Copy or Download
Copy the result to your clipboard or download it as a text file to paste into your project.
Embed Images Right Inside Your Code
A Base64 string lets you put an image straight into your HTML, CSS, or JavaScript instead of linking to a separate file. As a data URI it carries the image type and the encoded bytes together, so the browser can show it with no extra request. That is handy for small icons, inline email images, and quick prototypes.
This tool reads your image and encodes it on the spot. Pick the output you need, a plain data URI to drop into a src, raw Base64 to use in code, or a finished CSS background, HTML img tag, or Markdown line. It also shows the original size next to the encoded size, since Base64 always adds about a third to the file.
Everything runs in your browser, so the image never leaves your device. Use it for the cases where inlining helps, and keep larger images as normal files where a separate request is cheaper.

FAQ
Frequently Asked Questions
Common questions about Base64 images.
What is a Base64 image?
It is an image encoded as plain text. As a data URI it can be placed directly in HTML or CSS so the browser shows it without loading a separate file.
When should I use Base64 images?
They suit small images like icons and inline email graphics, or quick prototypes. For larger images a normal file is usually better since Base64 adds size.
How much bigger does the image get?
Base64 adds roughly a third to the file size. The tool shows the original size next to the encoded size so you can compare.
Which image formats are supported?
PNG, JPG, GIF, SVG, WebP, BMP, and ICO all work, and the original image type is kept in the data URI.
Is my image uploaded anywhere?
No. The image is read and encoded entirely in your browser. Nothing is uploaded, logged, or stored on a server.
Is this image to Base64 tool free?
Yes, it is completely free with no signup and no limits. Everything runs on your device.
