How to convert ARW to TIFF
- Add your .ARW file - drop it in the box above or click to browse.
- Convert it to .TIFF in a few seconds.
- Download your new .TIFF file.
What to expect
- Export at 16-bit to preserve the full tonal range the Sony sensor captured - 8-bit TIFF discards shadow and highlight detail and offers no real advantage over a quality JPEG.
- A 16-bit TIFF from a modern Sony body can reach 50-150 MB per image; LZW compression (lossless) in the export dialog reduces file size with no quality penalty.
- The TIFF is a flat rendered image - raw editing adjustments stay in the
ARWsource and cannot be recovered from the TIFF; keep the originalARWas your archive.
Frequently asked questions
Does converting ARW to TIFF lose quality?
No - exporting at 16-bit with LZW or no compression is fully lossless. What you give up is the non-destructive raw flexibility of the
ARW, since the TIFF is a finished rendered image.Which bit depth should I choose?
Choose 16-bit. Modern Sony sensors capture high bit-depth raw data, and 16-bit TIFF preserves that full range; 8-bit is smaller but discards shadow and highlight detail.
Can I batch-convert a folder of ARW files to TIFF?
Yes - darktable and RawTherapee both support batch export through a queue; select multiple files, set the output format once, and process them all.
Should I keep the original ARW after exporting a TIFF?
Yes. The TIFF is your editing or print master, but only the
ARW holds the original raw sensor data for future re-processing as software and colour profiles improve.
