Images to Base64 Converter

Base64 encoding is a method of showing binary data such as images in the text format, making them ideal for embedding images into the preferred HTML, CSS, JSON or XML documents without needing separate image files.

Key Features

  • Plain Base64: Convert your image to plain Base64 text.
  • Data URI: Ready to embed directly in HTML, CSS, or JSON as data:image/png;base64...
  • HTML img Tag: Automatically wraps your Base64 string in a complete img tag.
  • CSS Background Image: Perfect for inline CSS styling with background-image: url(...).
  • XML Image: For including Base64 images in XML structures.
  • JSON Format: Embed your Base64 image as part of a JSON object.

Frequently Asked Questions

What is Base64 and why do people use it for images?

Base64 is a way to convert binary image data into plain text. Developers use it to embed images directly inside HTML, CSS, JSON, or XML without hosting a separate image file.

What is the difference between Raw Base64 and Data URI?

Raw Base64 contains only the encoded string. Data URI includes the MIME type prefix, such as data:image/png;base64,. If you are using an <img src> tag or CSS url(), you usually need the Data URI format.

How do I use Base64 in an HTML image tag?

Use the HTML output format and paste it directly into your page. A typical example looks like: <img src="data:image/png;base64,..." alt="..." />.

How do I use Base64 as a CSS background image?

Use the CSS output format and paste it into your stylesheet. Example: background-image: url('data:image/png;base64,...'); This is commonly used for icons and small UI assets.

Which format should I choose: HTML, CSS, Raw Base64, or Data URI?

Choose HTML for a ready-to-use <img> tag, CSS for background images, Data URI when a full value is required for src, url, JSON, or templates, and Raw Base64 when an API expects only the encoded string.

Can I convert SVG to Base64 too?

Yes, SVG files can be converted to Base64 like other images. Since SVG is text-based, it can also be embedded directly as SVG markup depending on your use case.

Is Base64 safe? Does my image get uploaded to a server?

This depends on how the tool is implemented. If the conversion runs in your browser, the image does not need to leave your device.

Why is my Base64 output so long?

Base64 increases file size compared to the original image. The output becomes long because every part of the image data is represented as text.

Why does my Base64 not work in HTML or CSS?

Common issues include using Raw Base64 instead of Data URI, incorrect MIME types such as image/jpeg vs image/png, or missing quotes in HTML or CSS. Switching to Data URI usually fixes the issue.

What is the JSON output used for?

JSON output is useful for APIs, logging, or storing image data. It commonly includes Base64 data along with metadata like filename, MIME type, and size.

What is the XML output used for?

XML output is used for systems that accept XML payloads, such as legacy integrations or document-based APIs. It wraps Base64 or Data URI data in a structured XML format.
