Building data URIs
Convert small image files into Base64 strings for inline CSS, HTML snippets, email templates, and quick prototypes.
Image to Base64
Use Image to Base64 when you need an inline image string for a data URI, a test payload, an email snippet, or a quick prototype. It is especially useful for small assets that need to move into code, markup, or browser-side debugging without a separate script.
Tool interface
What this tool does
Image to Base64 helps you encode an image file as Base64 in the browser for building data URLs, testing uploads, or preparing inline image samples for code and docs.
Related next steps include Base64 to Image, Base64 Encoder, and the Browser-based encoding and query tools page if you want to keep working on the same task from a different angle.
When to use it
Use it when you need an inline-ready Base64 string for a small asset, a data URI, a test payload, or a quick prototype. It is especially useful when an image has to move into code, markup, or a browser-side debug workflow.
If you need to confirm the encoded result still renders as an image, continue with Base64 to Image. For adjacent conversion work, the Browser-based encoding and query tools page is a useful next step.
How to use it
Upload an image file, review the generated Base64 string, and copy it when you are ready to reuse it in code or markup.
- Choose an image from your device so the tool can read it locally.
- Review the generated Base64 output and any preview or metadata shown alongside it.
- Copy the encoded string only after you confirm you selected the right file and format.

Testing image payloads
Use it when an upload flow, API request, or debugging task needs a Base64 image string that you can inspect and copy.
Preparing sample assets for docs
A Base64 string is useful when you want a portable example for code samples, bug reports, or implementation notes.
Checking the decoded result
If you want to turn the encoded string back into a visible image, continue with Base64 to Image.
