Convert ARW to HEIC

Short answer

ARW is Sony's raw format, written by Alpha bodies and holding the unprocessed sensor data. It is excellent to edit from and awkward to share, since most viewers show nothing at all. Converting ARW to HEIC gives you a compact, universally viewable copy while the original stays exactly as the camera wrote it.

All 2,748 conversions verified on macOS, Windows, and Linux against the shipping release, this one included. Every conversion runs entirely on your own computer.

How to convert ARW to HEIC

  1. Open Morphjet and drag in your ARW files, or point it at the whole card folder to do a shoot in one go.
  2. Choose HEIC as the output format. The photos stay on your machine the entire time.
  3. Pick where the converted copies land. Your originals are never touched or moved.

When to convert, and when not to

Convert ARW to HEIC when the editing is finished and you want the photo somewhere useful: on your phone, in a shared album, or in a backup that is not measured in tens of gigabytes. It is also the sensible step before handing photos to someone who does not have editing software.

Keep working from the ARW if you have not finished editing, or if the shot might need rescuing later. HEIC discards the headroom that makes raw worth shooting, and no later conversion brings it back.

Why not just use an online converter?

ARW files carry the full shooting record: camera body, lens, serial number, timestamps, and GPS coordinates if location was enabled. That is a precise map of where you were and when. Converting on your own machine means none of it is uploaded to anyone, and you can strip the location data on the way out if you would rather it did not travel with the photo.

Questions

Will I lose editing latitude converting ARW to HEIC?

Yes, and that is the trade you are making. A ARW file holds the sensor's full range, which is what lets you rescue a blown sky or push shadows later. HEIC stores a finished picture. Convert copies for sharing and storage, and keep the ARW files for anything you might still want to edit.

Is HEIC smaller than the original?

Considerably. A ARW frame from a modern Sony body is often 25 to 50 MB; the same photo as HEIC usually lands in single-digit megabytes with no visible difference at normal viewing sizes.

Will these open on an iPhone or Mac?

Yes. HEIC is the format Apple devices shoot in by default, so photos land in Photos, Messages and AirDrop without a conversion step or a plugin.

Does this need an internet connection?

No. The conversion runs on your own computer, so it works on a plane, in a hotel with bad wifi, or with networking switched off entirely.
