How to convert QOI to JPG
- Add your .QOI file - drop it in the box above or click to browse.
- Convert it to .JPG in a few seconds.
- Download your new .JPG file.
What to expect
- 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.
