Why convert images to WebP?

WebP files are typically 25-35% smaller than equivalent JPEGs and far smaller than PNGs, while supporting transparency. Smaller images mean faster page loads and better Core Web Vitals, which affects SEO.

Does WebP support transparency?

Yes. WebP supports full alpha transparency like PNG, at a fraction of the file size - ideal for logos on websites.

Can I convert WebP back to PNG or JPG?

Yes. Upload a WebP file and choose PNG or JPEG as the output format. This is useful when a platform or older tool doesn't accept WebP uploads.

Are my images uploaded anywhere?

No. Conversion happens entirely in your browser using the canvas API - files never leave your device.

PNG/JPG to WebP: Why It Matters for Your Website

Images are usually the heaviest thing on a web page. Serving the same picture as WebP instead of PNG or JPEG typically cuts 25-35% of the file size with no visible difference - and for graphics with flat colors (like logos and screenshots), savings of 60-80% versus PNG are common. Smaller images mean faster Largest Contentful Paint, better Core Web Vitals, and a measurable edge in Google rankings.

When to use each format

WebP - the default for websites in 2026. Supports transparency and is understood by every modern browser.
PNG - when a platform rejects WebP uploads (some email tools, older CMSs, print workflows) or you need a guaranteed-lossless master file.
JPEG - photographs destined for platforms that still prefer it; never for transparent logos.

Frequently asked questions

Is WebP lossless or lossy?

It can be both. This tool exports lossy WebP with a quality slider, which is the right choice for web delivery. For a lossless master, keep your original PNG.

Do all browsers support WebP?

Yes - Chrome, Firefox, Safari, and Edge have all supported WebP for years. It is safe to use WebP as your only web image format.
