What is image to Base64 & how it works

Embedding an image as text

Converting an image to Base64 turns its bytes into plain text you can paste directly into HTML, CSS, JSON or an email template as a data URL, so the image loads without a separate file or HTTP request.

That suits small icons, logos in HTML emails and single-file demos. For larger images it is usually a bad trade: the text is about 33% bigger than the file, cannot be cached separately, and delays the page it is embedded in. This tool reads the image in your browser and gives you a complete data URL to copy or download.

Data URL
data:image/png;base64,… embeds a file directly in HTML or CSS.
MIME type
The image/png or image/jpeg part that tells the browser how to decode it.
+33% size
Base64 text is about a third larger than the original bytes.

Frequently asked questions

Common questions about Base64 images
5 Q&A

For small, rarely changing images (icons, tiny logos, email template graphics) where saving an HTTP request matters. For photos and large images, a normal image file is faster and cacheable.

Yes, by about 33%. Compress and resize the image before converting it.

No. The file is read and encoded in your browser and never leaves your device.

In HTML: <img src="data:image/png;base64,iVBOR…">. In CSS: background-image: url("data:image/png;base64,iVBOR…");. Remove the data:…;base64, prefix if an API expects raw Base64.

Support is mixed: Gmail and some Outlook versions block data-URL images. For email, hosted images or CID attachments are more reliable.
