Technical Guide

Why WebP is worth using on your website

Smaller images make pages load faster, which helps your visitors, your PageSpeed results and your bandwidth bill.

🚀 Faster pages and Core Web Vitals

Large PNG and JPG files are one of the most common reasons a page feels slow, and they often decide your Largest Contentful Paint (LCP), one of Google's Core Web Vitals. WebP versions are usually 25-35% smaller, so pages load sooner, especially on mobile data.

💎 Keeps transparency

JPEG can't store transparent areas, but WebP can (8-bit alpha transparency). Transparent PNG logos, icons and illustrations keep their clean edges when converted to WebP.

🔒 Why in-browser conversion matters

Many online converters upload your files to their servers to process them. This one does the work locally in your browser using the Canvas API, so client photos and unreleased product shots stay on your device.

Performance & SEO

Compression, Speed & Google Rankings

How WebP affects page speed and your Core Web Vitals.

WebP is an image format developed by Google. Files are typically 25% to 35% smaller than PNG or JPEG at similar visual quality. Smaller images load faster, which improves Core Web Vitals such as Largest Contentful Paint (LCP), and page speed is one of the signals Google considers.
Yes. WebP supports full 8-bit alpha transparency, like PNG, and the files are usually noticeably smaller. Transparent logos, icons and product cut-outs convert well.
At the default 90% quality, most images look the same as the original while being smaller. Move the quality slider down for smaller files, or up if you need the closest match to the original.
