Complete Guide: SVG to Base64 Converter
Everything you need to know about using this tool effectively
The SVG to Base64 Converter transforms SVG vector files into Base64 encoded data URLs. SVG is already a text-based format, but encoding it to Base64 allows embedding in contexts that require a single data string. The tool processes everything in the browser, so your file never leaves your device.
This tool reads your SVG file, encodes the XML text into a Base64 string, and generates a ready-to-use data URL. Since SVG is text-based, the encoding is straightforward and preserves all vector data exactly.
Inline SVG in CSS
Embed Base64 encoded SVG icons directly in CSS url() properties for icon backgrounds without external files.
Single-file applications
Bundle SVG icons directly into HTML or JavaScript files to create self-contained applications.
Email templates
Encode SVG graphics as Base64 for embedding in HTML emails where external files may be blocked.
Configuration files
Store SVG icons as Base64 strings in JSON configuration files or databases.
Upload an image
Drag and drop or click to browse for your SVG file.
Convert
Click Convert. The tool encodes the SVG into a Base64 string.
Copy or download
Copy the data URL or download it as a text file.
Base64 encoding increases size by about 33 percent. For SVG, consider using URL encoding instead for smaller output.
Small SVG icons encode to compact Base64 strings suitable for inline use.
The data URL prefix for SVG is data:image/svg+xml;base64,...
For CSS embedding, you can also use URL-encoded SVG without Base64 for smaller strings.
Will the SVG data change?
No. Base64 encoding is a lossless text representation. The decoded SVG is identical to the original.
Is my file uploaded to a server?
No. All processing happens in your browser using JavaScript. The file never leaves your device.
What is the maximum file size?
The tool supports files up to 50MB. SVG files are typically small text files.
Can I use the data URL in CSS?
Yes. Paste the output into a CSS url() property. Use data:image/svg+xml;base64,... as the format.
Can I convert multiple files at once?
Yes. Upload multiple SVG files and the tool generates a Base64 string for each one.
