Compress an image to 1 MB

Aim at a hard 1 MB limit. The tool searches for the highest quality that still fits, and tells you the exact final size.

Your file is processed on your device and is never uploaded.

What this tool does

  • Automatically finds the best quality that fits 1 MB
  • Shows the original and final size side by side
  • Reduces dimensions too, if quality alone is not enough

Frequently asked questions

Why do I need an image under 1 MB?

1 MB is the limit most often quoted by content management systems and email attachments — large enough that it is about keeping pages fast rather than about strict storage limits.

Can any image be compressed to 1 MB?

Almost always without any visible change. A 1 MB target usually only needs the quality nudged down a little, and the dimensions are left alone.

What will the result actually look like at 1 MB?

Effectively indistinguishable from the original for most photographs. The quality is usually nudged down slightly and the dimensions are left alone entirely.

How does it hit the target?

It repeatedly re-encodes the image, adjusting quality by binary search until it finds the highest setting that still fits. If quality alone cannot get there, it progressively reduces the pixel dimensions as well. The whole search runs on your device, typically in under a second.

Which format gives the smallest file?

JPG for compatibility. WebP if this is destined for a web page — the same picture at the same quality typically lands near 700 KB, which is a real difference in load time.
