What is SVG to Base64?

SVG to Base64 reads an SVG file in your browser and encodes it as a Base64 string. The data URI output (data:image/svg+xml;base64,...) lets you embed the vector graphic directly in an HTML img src or CSS background-image without a separate file request. Alternatively, SVGs can often be inlined directly as encoded URIs without Base64, but Base64 is more universally compatible.

How to Use SVG to Base64

1

Drop an SVG file onto the upload area or click to browse.

2

Copy the Base64 string or data URI.

3

Paste into your HTML or CSS.

Common Use Cases

  • Embedding SVG icons inline in a stylesheet or component without an img tag.
  • Using an SVG as a CSS cursor image via data URI.
  • Storing SVG illustrations as Base64 in a config or JSON file.

Alternative

For inline SVGs in HTML you can paste the raw SVG markup directly — no encoding needed. Use Base64 when embedding in a CSS background-image or a non-HTML context.

Frequently Asked Questions

Should I use Base64 or URL-encode for SVGs?

Both work. URL-encoding (replacing < with %3C etc.) is slightly smaller. Base64 is more compatible across all browsers and use cases, particularly in older email clients.

Is my file uploaded?

No. The file is processed entirely in your browser.
