How The Converter Works

Choose Raw Base64 for the encoded image content alone, or Data URL to include its image type and prefix.

This is an encoding step, not a visual transform, so the original image bytes are preserved in the encoded output.

Quick Examples

For a JSON field that expects image bytes as Base64, select Raw Base64 before choosing the file.
For an HTML image source, use Data URL to include the image type along with the encoded content.
A PNG data URL starts with data:image/png;base64, while a JPEG data URL starts with data:image/jpeg;base64,.
Use Download Text to save a long encoded image string instead of copying it manually.

Frequently Asked Questions

Does this change the image format?

No. Base64 encoding preserves the original bytes. MIME type metadata is included only when you keep the full data URL form.

Does switching output modes keep my image?

No. Switching modes clears the selected image and output. Choose the mode first, then select your file.

Can I use PNG, JPG, GIF, and WebP here?

Yes. Any regular image format the browser can read as a file should work.

Can large images create very long output?

Yes. Large image files produce long text strings that can be harder to copy and display.

Useful Notes

Base64 text is larger than the original image file; encoding does not compress the image.

Check whether the destination expects raw Base64 or a full data URL before pasting the output.

The MIME Type field identifies the image format, such as image/png or image/jpeg.
