JPG and WebP - what's the difference?

JPG Standard photo

JPG is one of the most common image formats for photos and web images.

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 web platform and smaller file size is the priority. AVIF: Choose AVIF instead when you want the maximum possible file size reduction and the platform supports it.

Why People Convert JPG to WebP

Convert JPG files to WebP online for free. WebP produces files 25–35% smaller than JPG at comparable quality, making it the modern standard for web image delivery.

JPG has been the default photo format for decades, but WebP was specifically designed for the web and achieves noticeably better compression. Switching from JPG to WebP for web delivery reduces file sizes, speeds up page loads, and improves performance metrics — without any visible difference to the viewer.

The standard approach is to keep the JPG as the source file and produce WebP for delivery. This conversion is a routine step in web publishing, CMS image handling, and performance optimisation workflows.

Common situations where this helps

A website serves many JPG images and needs smaller file sizes to improve page load performance.

A blog, portfolio, or e-commerce site is optimising images for faster delivery and better Core Web Vitals.

A CMS or image pipeline accepts WebP and you want to serve more efficient versions of existing JPG assets.

A JPG photo needs to be uploaded to a platform that supports WebP and benefits from the smaller file size.

Common problems and fixes

The WebP output looks worse than the JPG.

Try a higher quality setting. WebP quality levels are not directly equivalent to JPG quality levels — a WebP at quality 80 may look different from a JPG at quality 80 for the same image.

The platform does not accept or display WebP files.

WebP is supported in all modern browsers. If a specific platform rejects it, check its accepted formats — some older tools or CMSes do not yet support WebP uploads.

I need transparency in the output.

JPG does not support transparency. Converting JPG to WebP produces an opaque WebP. If you need transparency, start from a PNG or SVG source with transparent areas.
