SVG to Data URI Converter – Embed SVG in CSS and HTML Free

Paste SVG code and get a data URI ready for CSS or HTML, free and private.

Turn SVG Code into a Data URI You Can Paste Anywhere

A data URI lets you put an image directly inside CSS or HTML, with no separate file to upload and no extra request for the browser to make. Instead of linking to an SVG file, you paste the code itself, encoded, into a url() value or an image source. This tool converts raw SVG code into that encoded form in seconds. It is free, it runs fully in your browser, and your SVG code never leaves your device. Nothing is uploaded to a server, stored, or seen by anyone else.

Designers use data URIs for small icons, patterns, and decorative shapes. A tiny logo in a stylesheet, a background pattern on a button, or a bullet icon in a list can all live inside the CSS file itself. That keeps a project tidy: one file holds the style and the small graphics it needs. It also removes the risk of a broken image link when a file moves or a folder is renamed.

How the Conversion Works

SVG is text, which is why it converts so well. The tool takes your code and URL-encodes the characters that would break a stylesheet, such as angle brackets, quotes, and hash signs. The result starts with data:image/svg+xml, followed by the encoded code. Browsers read that string exactly as if it were a file, and render the graphic the same way.

You can also choose base64 output. Base64 is a little longer, but it avoids every special-character problem, which makes it the safer choice for older tools and strict systems. URL-encoded output is shorter and easier to read, so it is the better default for modern CSS. Try both and compare the length shown under the result. For most small icons, the difference is only a few dozen characters.

Using the Tool

Paste your SVG code into the box. If you do not have code handy, press the sample button to load a small example and see the result right away. Choose the format, press convert, and the data URI appears below, together with a live preview of the graphic. That preview matters: it confirms the encoding worked before you copy anything into your project.

Press the copy button to put the whole URI on your clipboard. In CSS, use it like this: background-image: url(“data:image/svg+xml,…”). In HTML, paste it straight into an img src attribute. Keep the quotes around it in CSS. Without quotes, some characters can end the value early and break the rule.

Tips for Clean Results

Small SVGs work best as data URIs. Icons, logos, and simple shapes under a few kilobytes are ideal. A large, detailed illustration makes a very long string that is hard to manage in a stylesheet, and at that size a normal file is the better choice. If your SVG has an XML declaration at the top, you can usually drop it for a data URI, since the data prefix already tells the browser what the content is.

Watch out for the hash character in colours. A fill like #0f766e must be encoded as %230f766e, or the browser will treat everything after the hash as a fragment and cut the image off. This tool handles that for you, which is one of the main reasons to use a converter instead of pasting raw SVG into CSS by hand.

Common Uses

Front-end developers embed icons in buttons and navigation. Email designers use data URIs where external images are blocked. Teachers making worksheets embed small diagrams without managing image folders. Bloggers add decorative dividers and patterns without uploading files. In every case the benefit is the same: fewer files, fewer requests, and graphics that travel with the code itself.

Because the tool runs in your browser, it works on a phone, tablet, or computer, with no account and no install. Paste, convert, copy, and you are done. Your code stays private throughout, and the URI you produce is yours to use anywhere, in any project, as many times as you like.
