Frequently Asked Questions

Is this Image to Base64 converter free?

Yes, you can convert images to Base64 completely for free.

What is Base64?

Base64 is an encoding scheme that converts binary data into ASCII text, making it safe to embed in HTML, CSS, JSON, or transmit over text-based systems.

What is a Data URL?

A Data URL is a URI scheme that embeds file data directly into a URL string, like data:image/png;base64,... — allowing images to be embedded inline in web pages.

Can I convert PNG to Base64?

Yes, PNG images are fully supported.

Can I convert JPG to Base64?

Yes, JPG and JPEG images are fully supported.

Can I convert WebP to Base64?

Yes, WebP images are fully supported.

Can I convert SVG to Base64?

Yes, SVG files are fully supported. The SVG content is safely encoded as Base64 without being rendered or executed.

Can I use Base64 in HTML?

Yes. You can use a Base64 Data URL as the src attribute of an <img> tag to embed images directly in HTML without hosting the file separately.

Can I use Base64 in CSS?

Yes. Base64 Data URLs can be used in CSS as background-image values to embed images directly in stylesheets.

Why is Base64 larger than the original file?

Base64 output is usually about 33% larger than the original file because it encodes every 3 bytes of binary data into 4 ASCII characters. It is best for small images, icons, and embedded assets.

What is the maximum file size?

The maximum supported file size is 5MB to avoid performance issues with very large Base64 strings.

Are my files stored?

No, files are processed securely and never stored. Conversion happens on our servers and the result is returned immediately.

Does this work on mobile?

Yes, the tool is fully responsive and works on mobile devices.
