Browser-local SVG Processing

The SVG to Base64 utility processes SVG content in your browser. The raw SVG is not uploaded for processing; actual processing time depends on the file and your device. See the Privacy Policy for normal website requests and hosting logs.

About SVG to Base64

Convert raw SVG vector code into Base64 encoded data URIs for CSS background images, inline stylesheets, and JavaScript modules. Base64 encoding turns text markup into portable ASCII strings that embed seamlessly across web templates. Our encoder uses UTF-8 byte conversion so non-Latin text nodes and emoji glyphs survive intact.

How It Works

01

Input your SVG markup.

02

Select Base64 encoding.

03

Copy the compiled data URI.

Base64 encoding notes

SVG to Base64 converts readable SVG bytes into a Base64 Data URI string for CSS, HTML, or a JavaScript payload. Use the generated value where an opaque, self-contained representation is useful, and compare it with URL-encoded XML for size and maintainability.

What this tool does

  • Encodes SVG content as UTF-8 bytes and represents those bytes in Base64.
  • Adds a Data URI prefix suitable for common CSS or HTML image contexts.
  • Keeps the source processing inside the browser for direct copy or download.

Review before publishing

  • Base64 is opaque to code reviewers and can be larger than a compact URL-encoded SVG.
  • The containing CSS or HTML still carries the full payload and may lose independent asset caching.
  • Test quoting, escaping, CSP rules, and the target browser or build pipeline.

SVG input

<svg xmlns='http://www.w3.org/2000/svg' viewBox='0 0 4 4'><path d='M0 0h4v4H0z'/></svg>

Data URI shape

data:image/svg+xml;base64,PHN2ZyB4bWxucz0i...

Frequently Asked Questions

Is multi-byte Unicode supported?

Yes, UTF-8 text encoding handles non-Latin strings and emoji glyphs seamlessly.

How do I embed a Base64 SVG in HTML or CSS?

Use `url('data:image/svg+xml;base64,...')` in CSS or pass the string into an `<img>` `src` attribute.

What is the difference between Base64 and UTF-8 data URIs?

UTF-8 data URIs keep text readable while Base64 encodes string bytes into ASCII characters.
