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

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

The fastest path is the official qoiconv input.qoi output.png command from the reference QOI repo, which decodes and re-encodes with zero quality loss. Any modern ImageMagick (7.1.0-20 or newer) does the same, and both keep the full alpha channel.

Also to PNG: APM · PBM · XPM

Why convert QOI to PNG?

QOI is a young, fast, lossless format that few programs open, so people re-save to .png for universal compatibility in browsers, editors and OS previews. Because both are lossless RGBA formats, the conversion is truly pixel-for-pixel - nothing is degraded, only the container and compression scheme change.

How to convert QOI to PNG

qoiconv (official reference tool) FREE

Grab qoiconv from the phoboslab/qoi repo and run qoiconv input.qoi output.png. It picks encoder/decoder from the file extensions and converts losslessly.

ImageMagick OPEN-SOURCE

With ImageMagick 7.1.0-20 or newer run magick input.qoi output.png. QOI read/write is built in, so it also works for batch loops.

XnView MP APP

Open the .qoi file (read support was added in XnView MP 1.0.0), then File > Export... and choose PNG. XnConvert handles whole folders at once.

GIMP 3.0 OPEN-SOURCE

GIMP 3.0 added QOI import/export. Open the .qoi, then File > Export As... and type a .png name to save.

About these formats

.QOI Quite OK Image Format

A .qoi file is a Quite OK Image, a lossless raster image saved in an open format created by Dominic Szablewski in 2021 as a much faster alternative to PNG. It stores 24-bit RGB or 32-bit…

Quality & what to watch

  • 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.
