Compress Image

Compress Image is a fast, browser-based image optimizer that lets you shrink JPG, PNG, and WebP files without giving up control of your photos. You set the quality with a single slider, drop your files in, and download a smaller version in seconds — all without uploading anything to a server. The tool uses modern browser APIs (Web Workers and Canvas) so compression happens in parallel and never blocks the page. For most photos, a quality setting between 70% and 80% removes 50–80% of the file size with no visible loss. For PNG and WebP files, the same slider controls the encoder's lossy quality, so you get the right tradeoff for the format. When you compress more than one image at a time, the result is bundled into a single ZIP file for easy downloading. Use it before emailing photos, before posting to a website, or before uploading to platforms with strict size limits — the smaller files will load faster and save bandwidth without you having to think about it.
