About Image Compression
Image compression shrinks file size by removing data your eyes are unlikely to notice. There are two approaches. Lossy compression (used by JPEG and WebP) discards fine colour detail and high-frequency texture, which can cut file size by 60-90 % with little visible change. Lossless compression (used by PNG and lossless WebP) rearranges pixel data more efficiently without discarding anything, typically saving 10-30 %.
The right target size depends on where the image will be used. Passport and ID photos for government portals often need to be under 50 KB. Website hero images perform best between 80-150 KB for fast loading without visible blur. E-commerce product shots usually aim for 100-200 KB to balance detail and page speed. Social-media platforms re-compress uploads automatically, so starting with a clean 200-500 KB file gives you the best result.
If you already know the exact format you need, jump to a dedicated tool: JPG Compressor or PNG Compressor. For WebP, HEIC, BMP, TIFF, and other formats, start here — this compressor handles them all.
