QOI to PCX Converter
Processing entirely on your device — large files may take a moment.
Convert PCX files from retro games and clipart archives into PNG or JPG. If your files are still in QOI format, this page is the shortcut: QOI (Quite OK Image) is a 2022 lossless format with a ~200-line spec — PNG-class simplicity that compresses similarly fast.
iLoveConverter processes everything locally on your computer, which makes it private and fast: no upload wait, no server storage, no limits. Add as many files as you like — batch conversion is built in.

About the QOI format
QOI (Quite OK Image, 2021) is a lossless format defined in one short specification document: a stream of simple run-length and delta ops over linear pixels. An encoder fits in 300 lines, decodes faster than PNG, and compresses comparably for photographic content.
It has found a home in emulators, demoscene projects and hobby engines — anywhere people want images without a codec dependency. Viewers rarely support it, so converting QOI to PNG is the way to bring these files into normal tools.
+Strengths
- ✓Radically simple spec (~200 lines)
- ✓Lossless with fast decode
- ✓No patent or licensing questions
!Limitations
- −Almost no viewer support
- −Larger than modern codecs for many images
About the PCX format
PCX was the image format of the DOS decade: ZSoft Paintbrush's run-length-encoded raster that every scanner, game and clipart CD adopted because it was published, simple and fast on 286 hardware. The header is a fixed 128 bytes, the palette hides in the final 769, and the whole file can be decoded by one while-loop.
Retro gaming archives and 90s clipart collections are full of PCX files. Converting them to PNG or JPG finally makes them viewable — the pixels were always fine, the container was just ancient.
+Strengths
- ✓Decoded by a single RLE loop — no dependencies
- ✓Ubiquitous in DOS-era archives
- ✓Supports paletted and 24-bit variants
!Limitations
- −Effectively dead since Windows 95
- −Rows padded — some files have alignment quirks
- −256-color ceiling for most real-world files
Why convert QOI to PCX?
There is a concrete reason this conversion exists: Almost no viewer support PCX sidesteps that — Decoded by a single RLE loop — no dependencies If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this QOI to PCX converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting QOI to PCX?
No — PCX is a lossless format, so every pixel of the converted image matches your original QOI file. You can also adjust the quality/size balance before converting when the target format supports compression.
What happens to EXIF data and other metadata?
Conversions here re-encode the image, and re-encoding generally does not carry the original metadata over. If the EXIF data of your QOI files matters (camera model, GPS, timestamps), keep the original file as the master and treat the converted copy as the shareable version.
Will transparent areas survive the conversion to PCX?
Transparency is kept whenever PCX actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
