JPEG and WebP - what's the difference?

JPEG Standard photo

JPEG is a widely supported photo format used across cameras, websites, and apps.

WebP Web format

WebP is a modern image format designed for smaller file sizes and good visual quality.

WebP: Choose WebP when the destination is a modern website or app that supports it and file size matters. AVIF: Choose AVIF instead if you want even smaller files and the platform supports it — AVIF compresses more aggressively than WebP.

Why People Convert JPEG to WebP

Convert JPEG files to WebP online for free. WebP produces files roughly 25–35% smaller than JPEG at comparable quality, making it the preferred format for modern web delivery.

JPEG has been the standard photo format for decades, but WebP offers meaningfully better compression for the same visual quality. Serving WebP instead of JPEG on a website reduces page weight, speeds up load times, and improves performance metrics — without users noticing any difference.

The typical workflow is to keep the original JPEG as the source and serve WebP as the delivery format. This conversion is a common step in image optimisation pipelines, CMS publishing, and web performance improvements.

Common situations where this helps

A website or blog has many large JPEG images and you want to reduce their file sizes for faster page loads.

A product image gallery needs optimised delivery and the source files are JPEG.

You are optimising images for Core Web Vitals and want smaller file sizes without visible quality loss.

A CMS, e-commerce platform, or image CDN accepts WebP and you want to serve the more efficient format.

Common problems and fixes

The platform or browser does not display the WebP file.

WebP is supported in all major modern browsers. If an older platform or tool rejects it, use JPG or PNG instead.

The WebP output looks worse than the JPEG.

WebP quality settings work differently from JPEG. Try a higher quality setting to find the right balance between file size and visual fidelity for your content.

I need transparency in the output.

WebP supports an alpha channel, but JPEG does not have transparent areas. If you need a transparent WebP, start from a PNG source instead.

Frequently asked questions

How much smaller is WebP than JPEG?

Typically 25–35% smaller at comparable visual quality. The exact difference depends on the image content — photos with smooth gradients see the biggest gains.

Is WebP supported in all browsers?

Yes. WebP is supported in all modern browsers including Chrome, Firefox, Safari, and Edge. It is now a safe choice for web delivery.

Does WebP support transparency?

Yes. WebP supports an alpha channel. JPEG does not have transparent areas, so converting JPEG to WebP produces an opaque WebP unless you add a transparent background separately.

Can I convert multiple JPEG files to WebP at once?

Yes. Add multiple files and download each WebP result individually or use Download all.

Is this JPEG to WebP converter free?

Yes. It is free to use in your browser.
