Frequently Asked Questions
Is this Base64 image encoder free to use?
Yes, it's completely free with no login or usage limits.
Are my images uploaded to a server?
No. The image is read directly in your browser using the FileReader API and converted to a Base64 data URL locally — it's never uploaded anywhere.
What image formats can I encode?
The tool accepts PNG, JPEG, SVG, and WEBP files, and shows the file name, size, and MIME type alongside the generated output.
What output formats can I copy?
You can copy the raw Base64 data URI, a ready-to-use HTML <img> tag, or a CSS background-image declaration, each with a one-click copy button.
