Get a big photo under 1MB with minimal loss

A 1 MB cap is generous, which means you can keep nearly all the quality. Modern phone cameras still produce 5–12 MB files, so the work here is gentle: find the quality setting that just fits, and avoid shrinking dimensions unless absolutely necessary.

This tool searches for the highest JPEG quality under 1 MB and reports the final size and resolution, so you know exactly what you are uploading. It is ideal for forms, email and CMS uploads that reject anything over a megabyte.

  • Near-original quality

    With a roomy 1 MB budget, quality stays high and dimensions are kept.

  • Handles huge files

    Large 20–50 MP photos are processed in your browser without uploading.

  • Exact result shown

    See the final size and pixel dimensions on the result card before downloading.

# FAQ

Compress to 1MB: common questions

How do I reduce a 5MB image to under 1MB?

Drop it in the box above — the tool lowers quality only as far as needed to fit under 1 MB, and keeps the dimensions where possible.

Will my image look worse?

Barely, for most photos. A 5x reduction at this level is typically hard to spot at normal viewing size.

Is 1MB the same as 1024KB?

Yes, in the usual binary sense. The tool aims below 1,000,000 bytes to be safe under either definition.

Does it keep EXIF or location data?

No — the output is re-encoded, which drops most metadata such as GPS location.
