Buy me a coffeeWhat is WebP to Base64?
WebP to Base64 reads a WebP image file in your browser and encodes it as a Base64 string. WebP offers superior compression compared to JPEG and PNG. The data URI output (data:image/webp;base64,...) lets you embed the optimised image directly in HTML or CSS without a separate file request.
How to Use WebP to Base64
1
Drop a WebP file onto the upload area or click to browse.
2
Copy the Base64 string or data URI.
3
Paste into your HTML img src or CSS background-image.
Common Use Cases
- Embedding WebP images inline in a single-file HTML page.
- Using optimised WebP graphics in email templates.
- Prototyping pages with WebP images before setting up a CDN.
File size
WebP files are typically 25–35% smaller than JPEG at the same quality, making them a good choice for inline Base64 where size matters.
Frequently Asked Questions
Is my file uploaded?
No. The file is read and encoded entirely in your browser using the FileReader API.
Is WebP widely supported as a data URI?
All modern browsers support WebP data URIs. Older browsers (IE11, some older Safari) may not. Check caniuse.com/webp for compatibility details.
