What is image compression?
Image compression cuts a picture's file size by re-encoding it and, when needed, scaling it down. Sign-up forms, email attachments and social or e-commerce platforms often cap images at 100KB to 1MB, so oversized photos, screenshots and ID images get rejected until you compress them. image cat does this in your browser — free, private and instant — and keeps lowering the quality until the file lands on the target size you set, such as 200KB.
