Lower quality means a smaller file. Around 80% is usually indistinguishable from the original.

How it works
To convert a JPG to WEBP, drop it onto this page; WEBP usually produces a smaller file than JPG at the same visual quality, which is why it is worth using for images going onto a website.
WEBP typically produces files 25 to 35 percent smaller than a JPG of comparable quality. On a page carrying a dozen photographs that difference is straightforwardly worth having: less bandwidth, faster loading, and a measurable improvement in the Largest Contentful Paint score that search ranking takes into account.
The conversion decodes your JPG and re-encodes it through the browser’s built-in WEBP encoder. Because the JPG was already compressed once, this is a second lossy pass — but WEBP is efficient enough that the result is usually both smaller and visually indistinguishable at the default 80% setting. Every result in the list shows its before and after size so you can see exactly what you gained rather than taking it on trust.
Every current browser supports WEBP, as do modern versions of Windows, macOS, Android, and iOS. It is a safe default for images destined for a website. It is a poor choice for files you intend to email or hand to someone who will open them in desktop software, since support outside the browser is still uneven — send JPG for that.
Conversion runs on a canvas inside this page. No library is downloaded and no file is uploaded.
FAQ
How much smaller will the file be?
Usually 25 to 35 percent at matching visual quality, though it depends heavily on the image. Photographs with smooth gradients gain the most; images already compressed very aggressively gain the least.
Do all browsers support WEBP?
Yes. Chrome, Firefox, Safari, and Edge have all supported it for years. Support in non-browser desktop software is the part that is still inconsistent.
Should I use WEBP or AVIF?
AVIF compresses better still, but encoding is far slower and browser support arrived more recently. WEBP remains the safer default for most sites today.
Is the conversion lossless?
No. This uses lossy WEBP, controlled by the quality slider. Since the source JPG was already lossy, a lossless WEBP would preserve its compression artefacts at a much larger file size, which defeats the purpose.
