Frequently asked questions
Why does Google PageSpeed Insights recommend WebP?
WebP reduces image payload sizes by 30%–65% compared to legacy PNG and JPEG, directly improving Largest Contentful Paint (LCP).
Does PNG to WebP conversion preserve transparent backgrounds?
Yes, HTML5 Canvas WebP encoding preserves full 8-bit alpha channel transparency.
Is there a 2-file or 5-file cap like other converter sites?
No. Because your own CPU performs the encoding, Utilix never restricts how many files you can convert.
Can I convert WebP back into JPG or PNG?
Yes, simply select JPEG or PNG in the Output Format selector.
How fast is browser-native WebP transcoding?
Most 2MP–4MP images transcode in under 35 milliseconds per image.
