QUICK ANSWER
Is it possible to convert QOI to JPG?
Yes - QOI converts to JPG.

You can do it right here with our free converter - no sign-up, and your file is deleted right after.

Run magick input.qoi output.jpg in ImageMagick to decode the QOI and save a JPEG. Because JPEG is lossy and cannot store an alpha channel, expect some fine detail to soften and any transparency to be flattened onto a background.

Why convert QOI to JPG?

People convert QOI to .jpg to get a small, universally supported photo file for the web or sharing, trading QOI's lossless quality for JPEG's much smaller size.

How to convert QOI to JPG

ImageMagick OPEN-SOURCE

With ImageMagick 7.1.0-20 or newer, run magick input.qoi -quality 90 output.jpg; the -quality value controls the compression trade-off.

IrfanView FREE

Open the .qoi (with the QOI plugin installed) and use File > Save As, choosing JPG and setting the quality slider.

XnView MP FREE

Install the qoi-fu plugin, open the image, and export to JPG via File > Export or the batch-convert dialog.

GIMP OPEN-SOURCE

With the QOI plugin added, open the .qoi and choose File > Export As, saving with a .jpg extension and picking a quality level.

Quality & what to watch

  • JPEG is lossy, so re-encoding discards some detail and can introduce compression artifacts around edges.
  • JPEG has no alpha channel; any transparency in the QOI is flattened against a solid background, usually white or black.
  • Saving at high quality reduces but never fully removes artifacts, and the file is still not pixel-identical to the source.

Frequently asked questions

Will I lose quality converting QOI to JPG?
Yes. QOI is lossless but JPEG is lossy, so the conversion permanently discards some detail. Use a high quality setting to minimize it.
What happens to transparent areas?
JPEG cannot store transparency, so any alpha in the QOI is flattened onto a background color during export.
How do I keep the file looking good?
Export at quality 85-95 in ImageMagick, IrfanView or GIMP. Higher values mean fewer artifacts but larger files.
Can I convert many QOI files at once?
Yes. ImageMagick's mogrify -format jpg *.qoi and XnView MP's batch converter both process folders of images.
