Why Embed SVG as Base64
Five Ready Formats
Get the raw base64, a data URI, a CSS background-image rule, an HTML img tag, and a URL-encoded variant, each with its own copy button.
Smaller URL-Encoded Variant
The URL-encoded utf8 version is usually smaller than base64 for SVG, so your CSS and HTML stay lean while still embedding inline.
UTF-8 Safe
Encoding handles emoji, accents, and non-Latin characters correctly, so your SVG never breaks on special characters.
Cut an HTTP Request
Inlining a small SVG as a data URI removes a separate network request, which can speed up first paint for icons and logos.
100% Private
Encoding runs entirely in your browser. Your SVG is never uploaded, making this safe for private brand assets.
Free and Unlimited
No signup, no credits, no limits. Encode as many SVGs as you like and copy any variant in one click.
How to Encode SVG to Base64
Add your SVG
Drag and drop an .svg file, click to browse, or paste your SVG code into the box.
Get the variants
The encoder instantly generates the raw base64, a full data URI, a CSS background rule, an img tag, and a URL-encoded version.
Pick the right one
Use the data URI in src or href, the CSS variant in background-image, or the URL-encoded variant when you want the smallest string.
Copy and paste
Hit the copy button next to any variant and paste it straight into your stylesheet, HTML, or component.
Choose The Right Tool
Why this page exists
Use the SVG to Base64 encoder to embed a vector inline as a data URI for CSS, HTML, or JSON, removing a network request. Copy the raw base64, the data URI, a CSS background, an img tag, or a smaller URL-encoded variant.
Best for
- Inlining icons in CSS background-image rules
- Embedding small SVGs directly in HTML or React without a separate file
- Cutting an extra HTTP request for tiny vector assets
SVG to Base64 FAQ
A data URI lets you embed an image directly inside CSS or HTML instead of linking to a separate file. For SVG it looks like data:image/svg+xml;base64,PHN2Zy... and the browser decodes and renders it inline, with no extra network request.
For SVG, the URL-encoded utf8 variant (data:image/svg+xml,...) is usually smaller than base64 because SVG is text. Use the URL-encoded version when you want the leanest CSS or HTML. Use base64 when a tool or platform specifically requires base64 input.
Copy the CSS background-image variant and paste it into a rule, for example background-image: url("data:image/svg+xml;base64,..."). The icon then renders as a background with no separate image file to load.
Yes. The encoder is UTF-8 safe, so accents, non-Latin scripts, and emoji inside your SVG are encoded correctly and will render without breaking.
Inlining as a data URI works best for small SVGs such as icons and logos, where removing an HTTP request speeds up loading. For large or frequently reused SVGs, a separate cached file is usually better because the data URI adds weight to every page that includes it.
No. The encoding happens entirely in your browser, so the SVG never leaves your device. This makes the tool safe for confidential or unreleased assets.
