Image Compressor

Large image files are one of the biggest causes of slow websites and sluggish page loads. A single photo straight from a phone camera can be several megabytes, far more than is needed to display it crisply on a screen. Compressing images reduces their file size — often by 60 to 80 percent — while keeping them looking virtually identical, so your pages load faster, your visitors stay longer, and you use less bandwidth and storage.

There are two broad approaches to compression. Lossless compression shrinks a file without discarding any image data, so the result is pixel-perfect but the savings are modest. Lossy compression, used for JPEG and WebP, cleverly removes detail that the human eye barely notices, achieving much larger reductions. For photographs, a well-tuned lossy setting is almost always the right choice; the difference is invisible at normal viewing sizes but the file can be a fraction of the original.

Faster-loading images also improve your search ranking, because page speed is a factor Google considers, and they make a real difference to visitors on mobile data. This compressor does all its work inside your browser, so your images are never uploaded to a server — an important guarantee when you are handling client photos, product shots, or anything you would rather keep private.
