FAQ
Why convert JPG to WebP for my website?
Same visual quality, ~30% smaller files. Smaller images load faster, and Google ranks fast pages higher — image format is one of the cheapest Core Web Vitals wins you can get.
Do all browsers support WebP now?
Yes — Chrome, Firefox, Safari (since 14) and Edge all support WebP as of 2020. That's why it's safe to serve as your primary format today.
What quality setting should I use?
75-80 is the sweet spot for most photos: visually identical to the original at typical viewing sizes, with maximum savings. Our live preview shows the exact output size per file so you can decide with numbers.
Is batch conversion really unlimited?
Really unlimited. Bulk-convert hundreds of images — it all happens in your browser via WebAssembly, so there's no server quota for us to enforce. Your CPU is the only limit, and you can watch it work offline.
Can I convert WebP back to JPG later?
Yes — use our WebP to JPG converter. It's on the same site, same privacy model.
