How to convert JPEG to PCX
- Add your .JPEG file - drop it in the box above or click to browse.
- Convert it to .PCX in a few seconds.
- Download your new .PCX file.
What to expect
- PCX stores the image losslessly, but JPEG artifacts already in the source are preserved.
- Expect a larger file than the JPEG, since RLE compresses photos poorly.
- Very old PCX decoders handled high color depths inconsistently, so keep the target software in mind.
Frequently asked questions
Is any quality lost converting JPEG to PCX?
PCX uses lossless run-length encoding, so the conversion does not add new compression loss; however, it also cannot remove the lossy artifacts the JPEG already contains. The visible result matches the source.
Why convert a JPEG to PCX?
PCX is one of the oldest PC raster formats and is sometimes needed for compatibility with legacy software or older imaging tools that expect it. For modern use most people instead keep images as PNG or JPG.
Where can I open a PCX file?
Almost any image program reads PCX for free, including IrfanView or XnView on Windows, GIMP on any platform, and Preview on macOS. It is very widely supported by older and general-purpose viewers.
Will the PCX be larger than the JPEG?
Usually yes, because PCX's run-length encoding is far less efficient than JPEG's compression, especially on photographic content with lots of detail. The image data itself is unchanged.
