Image to Base64

Convert images into Base64 data URLs locally in your browser. Upload an image, preview it, copy the encoded output, or download the generated text file.

Base64 output

Base64 output will appear after uploading an image.

Data URL

Image preview

Upload an image to see the preview.

When to use Base64 images

Base64 data URLs are useful for small inline previews, prototypes, examples, and quick developer workflows where a separate hosted image file is inconvenient.

Avoid embedding large Base64 images in production pages unless you have a specific reason. Encoded text is larger than the original binary file and can make HTML, CSS, or JSON harder to maintain.

Local image encoding

Image to Base64 reads the selected image with the browser FileReader API and creates a data URL on your device. The original image is not modified or uploaded.

Copy only the Base64 payload when another system already provides the MIME prefix, or copy the full data URL when you need a paste-ready inline image value.

Image to Base64 questions

No. Image to Base64 uses the browser FileReader API locally. The selected image is not sent to a backend.

The Base64 value is the encoded payload. The data URL includes the MIME prefix, such as data:image/png;base64, so it can be pasted directly into HTML or CSS.

Base64 encoding increases text size compared with the original binary file. Large images can create very long output strings.

Yes. The generated data URL can be downloaded as a plain text file for development and prototyping workflows.
