SVG data URI

SVG data URI generator for CSS and HTML

Use this SVG data URI generator to encode SVG code for CSS background-image, HTML img src, or a plain data URL.

The tool cleans and minifies the SVG before encoding. It runs in your browser and does not upload the SVG.

Runs locally

The core file work happens in your browser where possible.

No upload

SVG and PDF files are not sent to a server for the browser tools.

Editable output

Preview, copy, clean, or download the result before you use it.

Clear limits

Complex print files, scans, and unsupported SVG features may need another workflow.

SVG data URI generator

Paste SVG code or load a .svg file. The encoded outputs are generated locally.

Usage note

Generate URI to see a note.

Best for

Use SVG data URIs for small icons, CSS masks, list bullets, interface details, and tiny background graphics that ship with a component.

CSS output

Copy the CSS background-image value when you need a ready-to-paste url("data:image/svg+xml,...") string.

Avoid for

Avoid data URIs for large illustrations, frequently reused assets, or files that designers and developers need to edit often.

Encode SVG for CSS background-image

An SVG data URI lets you use SVG directly inside CSS or HTML without a separate file request. It works well for small icons, masks, bullets, simple backgrounds, and UI details.

This tool cleans and minifies the SVG before encoding it. Use the CSS output for background-image, the plain data URI for code that expects a URL string, or the HTML img output for a quick inline image. If you are choosing between inline data and a normal asset, read SVG data URI vs SVG file.

Example SVG data URI workflow

  1. Paste a small SVG icon or load a local SVG file.
  2. Generate the URI and preview the cleaned, minified SVG.
  3. Copy the CSS, plain data URI, or HTML img snippet depending on where it will be used.

Large SVG files can make CSS harder to read. If the file is big, use the SVG minifier first or keep the SVG as a normal asset.

Common questions

Can I encode SVG for CSS background-image?

Yes. The tool generates a CSS-ready url("data:image/svg+xml,...") string for background-image and similar CSS properties.

Does the SVG data URI generator upload my file?

No. The SVG is cleaned, minified, encoded, and previewed in the browser.

When should I use an SVG data URI?

Use it for small icons, masks, bullets, and simple UI graphics. For large SVG files, a separate SVG asset is usually easier to cache and maintain.

Is an SVG data URI better than a separate SVG file?

Only for small graphics that are tightly tied to one component or CSS rule. A separate SVG file is usually better for large, shared, or frequently edited assets.
