About Image Compressor
Compress JPG, PNG, and WebP images to a target file size directly in your browser, reducing file weight for faster-loading websites, smaller email attachments, and quicker uploads — all without a visible drop in quality. Because compression happens on-device using a web worker, large photos never leave your computer.
Large images slow down pages, fill inboxes and hit upload limits. This image compressor shrinks JPG, PNG and WebP files to a target size while keeping them looking sharp. Compression runs on your device in a background worker, so your photos are never uploaded and even big images process quickly.
