SVG to Base64
This SVG to base64 tool encodes an SVG file into a base64 string, and optionally wraps it as a data URI (data:image/svg+xml;base64,...). Both work as inline sources for <img>, CSS background-image and JSON payloads.
Runs in your browser. No files leave your device.
How the svg to base64 tool works
The workbench above is a self-contained web application. When you drop a file, the browser reads it locally, runs the conversion, and writes the result to a downloadable blob. Nothing is uploaded to any server, and the tool keeps working even if you disconnect after loading the page.
Frequently asked questions
When should I inline SVG as base64?
Base64 SVG is useful when you cannot serve a static file, for example in email templates, JSON APIs, or CSS bundled through a build step. For plain web pages, prefer inline <svg> or a linked file, since they compress better.
Base64 vs URL-encoded SVG data URIs?
URL-encoded data URIs are usually smaller for SVG because SVG is text-heavy. Use the svg-to-uri tool if you want the URL-encoded form. Base64 is safer inside JSON or CSS files that struggle with quotes and hashes.
