Is WebP better than JPG?

For the web, usually yes: WebP produces smaller files at the same visual quality and adds transparency. JPG still wins where universal compatibility matters most.

Does converting JPG to WebP lose quality?

Lossy WebP re-compresses, so there is some loss, but at matching quality settings WebP keeps more detail per kilobyte than JPG. Use lossless WebP to avoid any loss.

Which format is best for logos?

PNG or lossless WebP. Both keep sharp edges and transparency, unlike JPG, which blurs edges and cannot be transparent.

In short

Use WebP by default on the web: it is typically 25–35% smaller than JPG or PNG at the same quality, supports transparency, and works in every modern browser. Keep JPG for maximum photo compatibility, and PNG or lossless WebP when you need sharp edges or transparency.

JPG, PNG and WebP each win in different cases. Here is when to use each for the best balance of quality, file size and compatibility.

JPG — photos and small files

JPG uses lossy compression that shrinks photographs dramatically with little visible loss. It is ideal for photos and complex images, but it does not support transparency and degrades a little every time it is re-saved.

PNG — transparency and sharp edges

PNG is lossless and supports transparency, making it the right choice for logos, icons, screenshots and graphics with text or sharp edges. The trade-off is much larger files than JPG for photographs.

WebP — the modern all-rounder

WebP supports both lossy and lossless compression plus transparency, and is typically 25–35% smaller than JPG or PNG at the same quality. Every modern browser supports it; keep a JPG or PNG fallback only for very old clients. Use WebP by default for the web, JPG for maximum photo compatibility, and PNG when you need lossless transparency.

How much smaller is WebP, really?

Google's own tests put lossless WebP around 26% smaller than PNG, and lossy WebP roughly 25–34% smaller than JPEG at equivalent quality. The savings are largest on photographs and detailed images, where every kilobyte counts toward page-load speed and Core Web Vitals. On tiny, flat graphics the absolute saving is smaller — a 2 KB icon has little left to trim.

Browser support and fallbacks

WebP works in every current browser — Chrome, Firefox, Edge, Safari and their mobile versions. If you still support very old clients, serve it through the HTML picture element with a JPG or PNG inside a source fallback, so modern browsers get WebP and the rest get the classic format. In practice, for most sites today a plain WebP is safe.

When not to use WebP

WebP is built for the web, not for everything. For print work, CMYK formats like TIFF or a high-quality PDF still rule, and a few email clients and older design tools can stumble on it. If a graphic is already just a couple of kilobytes as an optimised PNG, converting to WebP saves little while adding a step to your pipeline. The rule of thumb: reach for WebP on real photographs and detailed interface images served to browsers, and keep the classic formats where compatibility or print quality matters more than bytes.
