Why embed Base64 images in HTML or CSS?
Base64 Data URIs render immediately with the HTML document without waiting for separate image network round-trips.
Convert Image to Base64 String
Encode icons and images into inline Data URIs, HTML `<img>` tags, and CSS snippets.
Generate HTML <img> and CSS Background Snippets
Drop any image to immediately generate the raw Base64 string, full `data:image/...;base64,` URI, ready-to-paste HTML `<img src="..." />` tag, and CSS `background-image: url(...)` rule.
When to Use Base64 Encoded Images
Inlining small icons, logos, and single-file HTML email templates as Base64 eliminates extra HTTP network requests and prevents broken image links.
Impact of Base64 on Payload Size
Base64 encoding increases byte size by roughly 33%. You can compress your image inside our studio first before copying the Base64 output!
Frequently Asked Questions
What is the difference between Raw Base64 and a Data URI?
A Data URI includes the `data:image/png;base64,` prefix required by browsers, whereas Raw Base64 contains only the encoded ASCII characters for API payloads.
Is there a file size limit for Base64 conversion?
Our browser encoder handles files up to 10MB, though Base64 is recommended primarily for icons and graphics under 50KB.
