What is a MEF file?

MEF is a camera RAW format — the unprocessed sensor data your camera saves for maximum editing latitude. Because it isn't a standard image, most apps can't open it directly, so converting to PNG gives you a shareable picture.

Can I convert MEF to PNG without Photoshop or Lightroom?

Yes. Your MEF file is decoded with professional camera-RAW processing on our secure servers, so you don't need Photoshop or Lightroom — or any other software — installed. Upload the file, then download the finished PNG.

Will I lose quality converting MEF to PNG?

MEF is processed at full resolution. PNG output is lossless. For archival work keep your original RAW too.
