Converting JPG to WebP shrinks your photos by roughly 25–35% at the same visual quality, which is why WebP has become the default image format for fast websites. ImageCompressify re-encodes the JPEG with Google’s WebP codec entirely in your browser session—nothing is uploaded to permanent storage—so you get smaller files without losing noticeable detail.
JPG is excellent for photographs but its compression is dated. WebP supports both lossy and lossless modes plus transparency, and at an equivalent quality setting it consistently produces smaller files. For a typical 2 MB JPEG photo you can expect a WebP around 1.2–1.5 MB with no visible difference, which directly improves Largest Contentful Paint and other Core Web Vitals.
Drop your JPG (or a batch of them) onto the uploader, leave the format set to WebP, and pick a quality level—80 is a good default that matches JPEG quality 90 visually. Click Convert and download each result, or grab everything as a ZIP. You can also set a target file size in KB and ImageCompressify will find the highest quality that fits.
WebP quality 75–85 is the sweet spot for web photos. Below 60 you may start to see blocking in flat areas like skies; above 90 the file grows quickly with little visible gain. If you need pixel-perfect output (for editing or print), use lossless WebP instead, which is still smaller than the original JPG in most cases.
JPEG (Joint Photographic Experts Group) is a widely used lossy compression format for digital images. It is ideal for photographs and complex images where a slight loss of detail is unnoticeable.
WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. WebP typically achieves significantly smaller file sizes compared to PNGs and JPEGs.
Only slightly, and usually not visibly. At quality 80, WebP looks the same as a high-quality JPEG while being meaningfully smaller. You control the exact trade-off with the quality slider.
Yes. Every current version of Chrome, Firefox, Safari, and Edge supports WebP, so it is safe to use across the web today.
Yes. Upload as many JPGs as you like, convert them in one batch, and download all the WebP files together as a ZIP.
