SVG to Data URI
Convert SVG markup into a bare data URI you can drop straight into an img src, an HTML attribute, a JavaScript string, or your browser address bar. Choose URL-encoded or Base64, copy the ready-to-use data URI or a complete img tag, and see a live preview, all in your browser.
SVG to Data URI is a free tool that turns SVG markup into a ready-to-use data URI you can paste anywhere a URL goes: the src of an img element, an HTML attribute, a JavaScript string, or even your browser address bar. Pick URL-encoding for the smallest, most readable result or Base64 if you prefer, then copy the bare data URI or a complete img tag and see a live preview of exactly what it renders. Everything runs in your browser, so your graphic is never uploaded.
What is an SVG data URI?
A data URI is a way of embedding a file directly inside a URL instead of pointing to a separate file on a server. For SVG it looks like data:image/svg+xml,... followed by the encoded markup. Because the image travels inside the URL itself, you can drop it straight into an img src, an inline HTML attribute, a JavaScript variable, or paste it into the address bar to view the graphic. There is no extra network request and no separate .svg file to host, which makes data URIs handy for small icons and inline graphics.
How to convert SVG to a data URI
Turning your SVG into a data URI takes only a few steps:
- Paste your SVG markup into the input box.
- Choose URL-encoded for the smallest result, or Base64 if you need it.
- Click Convert to data URI.
- Copy the bare data URI for an img src or JavaScript, or copy the ready-made HTML img tag.
- Check the live preview to confirm it renders the way you expect.
URL-encoded vs Base64: which should I use?
Both produce a valid SVG data URI, but they encode the markup differently. URL-encoding only escapes the characters that are unsafe in a URL, so the result stays mostly human-readable and is usually smaller than Base64 for SVG, which is why it is the recommended default. Base64 rewrites the whole file into a compact alphabet of letters and digits; it is slightly larger for SVG but is the safest option when a tool or pipeline mishandles raw angle brackets and quotes. For most icons and inline graphics, URL-encoding gives you the smaller, cleaner result.
Where can I use an SVG data URI?
Anywhere a URL is accepted. The most common spots are the src of an img element and the href of a link or object, but you can also feed a data URI to the JavaScript Image constructor, store it in a variable, use it as a favicon, or paste it into your browser address bar to preview the artwork. If you specifically want a CSS background-image: url(...) snippet instead, our SVG to CSS tool wraps the same data URI in a CSS declaration for you.

Frequently asked questions
Is the SVG to data URI converter free?
Yes. Every tool on ToolsSoup is completely free, with no account, sign-up, or hidden limits.
Should I pick URL-encoded or Base64?
URL-encoded is recommended for SVG because it is usually smaller and stays mostly readable. Choose Base64 only if a tool in your pipeline mishandles the raw angle brackets and quotes that URL-encoding leaves in place.
Can I use the data URI in CSS?
You can, but if you want a background-image: url(...) snippet specifically, the SVG to CSS tool wraps the same data URI in a ready-to-paste CSS declaration. This tool focuses on the bare data URI and an HTML img tag for use in markup, JavaScript, or the address bar.
Is my SVG uploaded anywhere?
No. The conversion and preview run entirely in your browser, so the markup you paste is never sent to or stored on any server.
