SVG ↔ Data URI Converter
About SVG to Data URI
The SVG to CSS Data URI & Base64 Encoder converts raw SVG markup into URI-encoded (`data:image/svg+xml,...`) and Base64 (`data:image/svg+xml;base64,...`) strings formatted for CSS `background-image`, HTML `<img>`, and Markdown embeds.
How to Use SVG to Data URI
Step 1
Paste SVG code or drag-and-drop an `.svg` file.
Step 2
Select output format (UTF-8 URI encoded or Base64).
Step 3
Inspect the live image preview.
Step 4
Click "Copy CSS url()" or "Copy Raw Data URI".
Practical Use Cases for SVG to Data URI
CSS Background Image Inlining
Embed vector icons and patterns directly into CSS `background-image: url("data:image/svg+xml,...")` declarations without external image requests.
Single-File HTML & Email Template Bundling
Inline vector logos into self-contained HTML email templates where external SVG references might be blocked.
Input & Output Examples
Encoding SVG to UTF-8 URI Data String
<svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><circle cx="12" cy="12" r="10" fill="#3B82F6"/></svg>
data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 24 24'%3E%3Ccircle cx='12' cy='12' r='10' fill='%233B82F6'/%3E%3C/svg%3E
Key Features & Performance
- ✓Encodes in UTF-8 percent-encoded Data URI (smallest size for CSS) and Base64 format.
- ✓Generates ready-to-paste CSS `background-image: url(...)` and HTML `<img src="..." />` snippets.
- ✓Auto-optimizes double quotes to single quotes to minimize `%22` encoding bloat.
- ✓100% Client-Side generation.
- ✓1-Click Copy Data URI.
Key Terminology & Definitions
UTF-8 SVG Data URI
A URI scheme that directly includes encoded SVG text without Base64 overhead, resulting in ~30% smaller file sizes for CSS inlining.
`data:image/svg+xml;base64`
A binary Base64 representation of an SVG file commonly used in legacy systems and email clients.
