What is image compression?
Image compression reduces a picture's file size by re-encoding and, if needed, down-scaling it. Sign-up forms, website attachments and social or e-commerce platforms often cap images at 100KB–1MB, and compression lets oversized photos, screenshots and ID images fit those limits while staying as sharp as possible. image cat does it right in your browser — no upload, free, instant and private — and converges on the target size you set (such as 200KB) automatically.
