1MBCompress image to 1MB
Quick answer
Compressing to 1MB is near-lossless: the size drops sharply but quality barely changes — ideal for visa documents and high-resolution photo uploads.
1MB (about 1024KB) is a generous target — big enough to bring a four-or-five-megabyte original under an upload limit, yet with almost no visible quality loss. Drop an image in and image cat compresses it toward 1MB locally — never uploaded.
Why 1MB is near-lossless
Original phone photos are often 3–8MB, much of it redundancy your eye can't see. Compressing to 1MB usually just strips that redundancy, keeping portrait, landscape and text detail intact, with no visible before-and-after difference.
When to use 1MB
Visa systems, formal documents and high-resolution photos you may print or enlarge later are best served by 1MB. It needs almost no compromise between meeting a size limit and keeping quality. If limits are tighter, consider 500KB or 200KB.
Frequently asked questions
Barely. Plenty of redundant data is removed, but key detail — faces, text, texture — is kept, so before and after are usually indistinguishable by eye.
If your system allows 2MB, it keeps more headroom and is closer to lossless. If the cap is under 1MB, 1MB is already plenty sharp.
No. Compression runs locally in your browser, files are never uploaded, and it's free with no file-count limit.
