What Makes WebP Better?
WebP is a modern image format created by Google that delivers high quality at a fraction of the file size. It combines the best of JPG (photo compression), PNG (transparency), and GIF (animation) in a single format.
Why websites love WebP
- Faster loading: Smaller images mean pages render faster, improving Core Web Vitals scores.
- Cheaper storage: Hosting bills shrink when images take 60% less space.
- Better SEO: Speed is a ranking factor; faster pages rank better.
- Smaller bandwidth: Visitors on mobile data download much less.
Lossless and lossy
WebP supports both lossy encoding (great for photos) and lossless encoding (perfect for logos and screenshots). Use 100% quality here for lossless output, or 80% for near-lossless photos at a fraction of the size.
Convert in your browser
Desktop converters require installs and online converters upload your images to their servers. Toolza converts locally with the canvas API — your images stay on your machine from start to finish.
Frequently Asked Questions

WebP typically delivers 25–80% smaller files than JPG and PNG at the same visual quality, which means faster pages, cheaper storage, and quicker uploads.
Yes. WebP supports an alpha channel, so PNG transparency survives the conversion.
All modern browsers — Chrome, Edge, Firefox, Safari, and Opera — have supported WebP for years.
80% is a great default: near-lossless for photos. For simple logos and graphics, even 50–60% looks fine and saves the most space.
