What is WebP to Base64 Converter?
WebP to Base64 Converter encodes a WebP image as text for direct use in code and data files. The output includes a data URL prefix that can be pasted into HTML, CSS, JavaScript, or JSON. The tool reads the WebP in the browser and produces the encoded string without changing the image file.
How does WebP to Base64 Converter work?
This tool reads the WebP file bytes and converts them to Base64 text. Base64 is a transport encoding rather than an image edit, so the decoded WebP is identical to the source while the encoded string is larger than the binary file.

Frequently Asked Questions
Will the image quality change?
No. Base64 encoding is a lossless text representation. The decoded image is identical to the original WebP.
Is my image uploaded to a server?
No. All processing happens in your browser using JavaScript. The image never leaves your device.
What is the maximum file size?
The tool supports images up to 50MB. WebP files are typically small.
Can I use the data URL in CSS?
Yes. Paste the output into a CSS url() property. The format is data:image/webp;base64,...
Can I convert multiple images at once?
Yes. Upload multiple WebP files and the tool generates a Base64 string for each one.
