TinyPNG is a great, well-known image compressor. If you are looking for a free alternative that needs no account, LightPIX compresses PNG, JPEG and WebP by up to 80% with no signup, no watermark and no monthly sign-in — and your images are processed over HTTPS and deleted right after compression, never stored.
Drop up to 20 images at once (up to 16 MB each), adjust the quality, and download them individually or as a ZIP. Prefer to automate it on your site? There is also a free LightPIX WordPress plugin.
