Prepare images for the web
Resize, compress, and convert images before you upload them to a site or store.
Image Resizer
Drop in images and set a width, a height, or a box to fit them inside. The resampling runs on our server with libvips, which uses a proper Lanczos filter rather than the bilinear scaling a browser canvas does — visible on any reduction of more than about half. Aspect ratio is preserved unless you explicitly ask for a mode that does not.
Image Compressor
Type the size you need — 200 KB, 1 MB, 20 KB — and each image is encoded repeatedly until it fits, keeping the highest quality that still meets your budget. Quality is reduced first and dimensions only if quality alone cannot get there, which is the order that leaves a photo looking like a photo. All of the search is done for you rather than left as a slider to fiddle with.
WebP to JPG
You saved an image from a website and got a file ending in .webp that your photo editor, your printing service, or the form you are filling in refuses to accept. This converts it to an ordinary JPG, in batches. It also explains where WebP files come from, because knowing that makes them much less annoying.
