Convert to or from WebP format

WebP Converter — Free, Fast & Private

WebP is a modern image format developed by Google that produces significantly smaller files than JPEG and PNG. Converting your images to WebP can reduce page load times and bandwidth usage by 25-35% compared to JPEG.

MiniPx converts in both directions. Convert JPG and PNG to WebP for web delivery, or convert WebP back to JPG and PNG for compatibility with apps and services that do not yet support WebP.

WebP supports both lossy compression (like JPEG) and transparency (like PNG), making it versatile for all types of web images. A single format that handles photos, graphics, and icons with transparency.

Browser support for WebP is now near-universal. Chrome, Firefox, Safari, Edge, and all major mobile browsers support WebP. The main compatibility gap is with older desktop applications like Photoshop (pre-2022) and some email clients.

All conversion happens in your browser. Your images are never uploaded to any server. MiniPx handles batch conversion — add multiple files and convert them all at once.

Frequently asked questions

How much smaller are WebP files?

WebP files are typically 25-35% smaller than JPEG at equivalent visual quality. For PNG images with transparency, WebP can be 26% smaller while maintaining the alpha channel.

Do all browsers support WebP?

Yes, all modern browsers support WebP including Chrome, Firefox, Safari (14.1+), Edge, and mobile browsers. Only Internet Explorer and very old browser versions lack support.

Should I use WebP or AVIF?

AVIF produces even smaller files than WebP but has less browser support and slower encoding. WebP is the safer choice for broad compatibility. For cutting-edge optimization, use AVIF with WebP as fallback.

Can I convert WebP back to JPG?

Yes. MiniPx converts WebP to JPG or PNG. Note that converting from WebP (lossy) to JPG involves a generation loss since both are lossy formats.

Does WebP support transparency?

Yes. WebP supports an alpha channel for transparency, similar to PNG but with much smaller file sizes. Convert PNG graphics with transparency to WebP for significant size savings.

Can I batch convert to WebP?

Yes. Add multiple images and convert them all to WebP at once. Mix input formats in a single batch — each file is processed independently.
