How to convert RW2 to JPEG with FileFlip

  1. Select the RW2 files

    In Finder or on the Desktop. One file, or a whole folder with ⌘ A.

  2. Press ⌥ F

    FileFlip opens next to the selection and lists the formats it can make from RW2. Type “JPEG” to jump to it.

  3. Choose JPEG and press Return

    The JPEG files appear next to the originals. To make them smaller first, press ⇥ and lower the quality or size.

RW2 and JPEG

Raw files are large and most apps and websites can’t show them, so they have to be developed into a regular image before sharing. JPEG opens everywhere, from email and websites to Windows PCs and photo printing services.

What changes when you convert

  • JPEG is lossy: the file gets much smaller and some fine detail is discarded. At high quality settings the difference is hard to notice.
  • A raw file is unprocessed sensor data. Converting develops it into a finished image, so keep the RW2 if you may want to edit it later.

Other ways on a Mac

For one file now and then you may not need FileFlip. These work with what’s already on your Mac.

Preview

Open the RW2 in Preview, choose File → Export, pick JPEG from the Format menu and click Save. For several files, open them together, select all thumbnails in the sidebar and choose File → Export Selected Images.

Works when macOS supports your camera model.

Photos

If the pictures are in your Photos library, select them, choose File → Export → Export Photos and set Photo Kind to JPEG.

Good for pictures already in your library.

Terminal

The sips command converts images in place or into a new file.

sips -s format jpeg DSC_0001.rw2 \
  --out DSC_0001.jpg

Built into macOS and good for scripts. Run sips --formats to see what your macOS version can read and write.

Questions about RW2 and JPEG

Does converting RW2 to JPEG lose quality?

JPEG is lossy: the file gets much smaller and some fine detail is discarded. At high quality settings the difference is hard to notice.

Can I convert many RW2 files at once?

Yes. Select them all in Finder, press ⌥ F and choose JPEG. Progress moves to the menu bar, so you can close the panel and keep working.

Will the JPEG keep the date, camera and location?

Yes, metadata is copied by default. Turn on “Remove location” in the options before you share photos publicly.

Should I keep the RW2 file?

Yes. The raw file holds more information than any finished image, so keep it if you may want to edit the photo again.

Where is the JPEG file saved?

Next to the original, with the same name and the .jpg extension. The RW2 file isn’t changed. In Settings you can choose a different folder instead.

Can I convert JPEG back to RW2?

No. FileFlip opens RW2 files but doesn’t save them.

Convert a whole shoot at once

FileFlip also handles video, audio, PDFs, documents and data files. Requires macOS 14 Sonoma or later.
