Reduce Image Size from MB to KB
If your image is measured in megabytes and the upload limit is in kilobytes, this is the page you need. Pick a target — 2MB, 1MB, 500KB or lower — and the compressor does the rest.
Large files are handled in small passes with progress feedback, so the page stays responsive instead of freezing.

MB to KB, in practice
1MB equals 1024 KB. Going from an 8MB photo to 200KB is a 97.5% reduction, and for on-screen viewing it is usually indistinguishable from the original.
Handling very large images
Our engine guards against browser memory limits.
- Files up to 40MB are accepted
- Each compression pass yields back to the browser so the UI never locks
- Progress messages show exactly which quality or dimension step is running
