What is this tool?
Image to Base64 Converter reads an image file and encodes it as a Base64 data URI — a text representation of the image that can be embedded directly inside HTML, CSS or JSON without a separate file request. The conversion happens entirely in your browser using the FileReader API.
Common uses
- Embedding a small icon or logo directly in CSS as a background-image
- Inlining an image in an HTML email where external images may be blocked
- Including an image inside a JSON payload or config file
- Avoiding an extra network request for a tiny, frequently used image

FAQ
Does Base64 encoding increase the file size?
Yes, Base64 text is roughly 33% larger than the original binary file, so it's best suited to small images.
What does the output look like?
It's a single line starting with "data:image/png;base64," followed by the encoded image data, ready to use directly as a src or background-image URL.
Is my image uploaded to a server?
No, the encoding happens entirely in your browser — your image never leaves your device.
