Compress a WebP to 100 KB
A 100 KB WebP gives you a clean, web-ready photo that often beats a same-size JPG on sharpness. WebP is lossy, so the tool dials quality down in small steps until the file matches 100 KB while the output stays WebP.

What 100 KB looks like in WebP
100 KB of WebP carries a crisp photo around 800x800 to 1000x1000 pixels with very little visible loss. The same 100 KB in JPG would usually look a touch softer, because WebP compresses photographic detail more efficiently. Since WebP is lossy, the encoder can step quality down until it reaches 100 KB precisely.
Every modern browser renders WebP, so a 100 KB WebP is a strong choice for fast-loading pages. The tool keeps the output as WebP, so you do not lose that efficiency by switching formats.
Picking WebP for the job
For websites, product images, and app assets, a 100 KB WebP balances quality and speed well. It is large enough to look good on a high-resolution screen yet light enough to load quickly.
Note that a handful of older programs still cannot open WebP, so check where the file is going. To build a WebP from a JPG or PNG, use convert to WebP. For a different target size or input format, compress to any size gives you the dial.
