Frequently Asked Questions
Is WebP better than JPG for websites?
Yes. WebP files are 25-34% smaller than equivalent JPEG images. Google recommends WebP for faster page loads and better Core Web Vitals scores.
Do all browsers support WebP now?
Yes — WebP has over 97% global browser support including Chrome, Firefox, Edge, Safari 14+, and all modern mobile browsers.
Is JPEG the same as JPG?
Yes — JPG and JPEG are exactly the same format. The three-letter "JPG" extension exists only because old Windows systems limited file extensions to three characters. This converter handles both .jpg and .jpeg files identically.
Does converting JPG to WebP lose quality?
At quality settings of 80% or higher, the difference is visually imperceptible for photographs. Since JPG is already a lossy format, converting at high quality preserves everything your eye can see while cutting file size by roughly a third.
What WebP quality setting should I use?
80–90% is the sweet spot for photos — near-identical visuals at a fraction of the size. Use 90%+ for hero images and photography portfolios, and 70–80% for thumbnails and background images where small artifacts are invisible.
Can I convert WebP back to JPG?
Yes. Toolyy's image converter works in both directions — drop a WebP file in and choose JPG as the output format to convert back for apps that don't accept WebP.

JPG or JPEG — What's the Difference?
Nothing — JPG and JPEG are exactly the same image format. The shorter "JPG" extension is a relic of early Windows systems that limited file extensions to three characters. Whether your photo ends in .jpg or .jpeg, this converter processes it identically and outputs the same optimized WebP file.
Why Convert JPG to WebP?
Faster page loads: A typical 500 KB JPEG photo becomes a ~330 KB WebP at the same visual quality. Multiply that across every image on a page and load times drop noticeably, especially on mobile connections.
Better Google rankings: Page speed is a ranking factor, and Google PageSpeed Insights explicitly flags JPEG images with the recommendation "serve images in next-gen formats" — WebP is that next-gen format.
Lower bandwidth costs: If you pay for CDN or hosting bandwidth, a one-third reduction in image weight directly cuts your bill.
Recommended Quality Settings
For photographs, 80–90% quality is the sweet spot — visually identical to the original at a fraction of the size. Use 90%+ for hero images and photography portfolios. Drop to 70–80% for thumbnails and decorative backgrounds where small artifacts are invisible.
