What is SVG to Base64 Converter?
SVG to Base64 Converter encodes an SVG file as a data URL for direct use in code and configuration files. SVG is already text-based, but Base64 is useful when a system expects a single encoded asset string. The tool reads the SVG in the browser and produces the encoded output without changing the vector data.
How does SVG to Base64 Converter work?
This tool reads the SVG XML text and converts it to Base64. The decoded SVG is identical to the source file, but the encoded string is larger than the original text and includes a data:image/svg+xml;base64 prefix when exported as a data URL.

Pro Tips
- 1
Base64 encoding increases size by about 33 percent. For SVG, consider using URL encoding instead for smaller output.
- 2
Small SVG icons encode to compact Base64 strings suitable for inline use.
- 3
The data URL prefix for SVG is data:image/svg+xml;base64,...
- 4
For CSS embedding, you can also use URL-encoded SVG without Base64 for smaller strings.
Frequently Asked Questions
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.
