How to convert QOI to PNG
- Add your .QOI file - drop it in the box above or click to browse.
- Convert it to .PNG in a few seconds.
- Download your new .PNG file.
What to expect
- Both formats are lossless, so the image itself is unchanged; only file size differs since PNG uses zlib compression.
- QOI has no metadata support, so there is nothing extra to lose, but PNG output will not carry EXIF/ICC unless you add it.
- PNG files are often larger than the equivalent QOI for photographic content.
Frequently asked questions
Does converting QOI to PNG lose quality?
No. Both formats are lossless, so the decoded pixels and the alpha channel are identical after conversion.
What is the simplest command?
qoiconv input.qoi output.png using the official reference tool, or magick input.qoi output.png with ImageMagick.Why is my PNG bigger than the QOI?
QOI's run-length scheme can beat PNG's zlib on some images. That is a size trade-off, not a quality one.
Can I batch-convert a whole folder?
Yes. Use XnConvert (XnView MP) for a GUI, or loop
magick over the files on the command line.
