About Image Compressor
Image compression lowers file size by reducing pixel dimensions and encoding quality. With the quality slider and a longest-edge limit you control the result, and you see the size saved for every file. For JPG and WebP, quality 75–85 is usually indistinguishable from the original. PNG is lossless, so convert to WebP or resize to shrink it. Everything runs in your browser; nothing is uploaded.
FAQ

Is it free? Do I need an account?
The tool is free and needs no registration.
Does it work on a phone?
Yes, in modern desktop and mobile browsers; large files depend on your device power.
