What happens when you convert PCX to PDF
- ImageMagick, the open-source image toolkit, reads the PCX on our conversion server and places it on a PDF page the size of the image, stored losslessly.
- This conversion runs on our server: the file is uploaded, converted, and deleted together with the result as soon as the result has been sent back to you. Nothing is kept. Files up to 25 MB are accepted.

- Press "Convert to PDF". The file is uploaded to our conversion server, converted in a few seconds, and deleted together with the result as soon as the result is sent back.
- Save each PDF with its download button. Our server has already deleted both your PCX and the PDF by then.
Why convert PCX to PDF?
PCX files usually come from DOS-era graphics, old games and scanning, fax and label software. People convert them to PDF because a PDF looks the same on every device and is what forms, portals and printers ask for.
In short, PCX is good at what it was made for, and PDF is the more practical choice when the file has to open, upload or print somewhere else. PCX does not open in browsers; IrfanView, GIMP, Paint.NET and Photoshop open it, while PDF opens in every browser's built-in viewer.

About PCX and PDF files
What is a PCX file?
PCX was the format of ZSoft PC Paintbrush for DOS and one of the first image formats widely used on PCs. It compresses each row with simple run-length encoding, so flat artwork stays small while photos barely shrink.
What is a PDF file?
A PDF fixes the layout of every page so it looks the same on any device. Converting a PDF to an image renders each page to pixels; converting an image to PDF wraps it as a page.
PCX to PDF not working? Common problems
- "Files up to 25 MB can be converted." Server conversions have a size limit. Save the image at a smaller size first.
- "The conversion took too long and was stopped." Very long or complex files can pass the 90 second limit. Split the file and convert the parts.
- "This file is not really in PCX format." The converter checks every file before it runs anything, so a file of another format renamed to .pcx is refused. Choose the page for its real format.
Convert PCX to PDF from the command line
ImageMagick does the same on your own computer:
magick input.pcx output.pdfConverting on your own computer keeps the file entirely local, which is worth it for very large or very sensitive documents. For everything else, the converter on this page does it without installing anything.
PCX to PDF converter FAQ
Will I lose quality converting PCX to PDF?
No. PDF is stored losslessly, so every pixel of the PCX is kept.
Why is the PDF a different size from the PCX?
Often larger than the PCX, because the pixels are stored in the PDF without lossy compression, and PDF adds its own page description around them.
Are my PCX files uploaded?
Yes, for this conversion. A faithful PCX to PDF conversion needs ImageMagick, the open-source image toolkit, which cannot run in a browser. The file travels over an encrypted connection, is converted in a private temporary folder, and is deleted together with the PDF as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several PCX files to PDF at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a PDF file?
PDF opens in every browser's built-in viewer. PDF is common for documents, forms, invoices and print-ready files.
Is this PCX to PDF converter free?
Yes. There is no sign-up and no watermark. Because this conversion uses our server, there is a fair-use limit of 25 MB per file and a number of files per hour, which stops the service being overloaded.
Can I convert PCX to PDF on my phone?
Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The conversion happens on our server, so it is as fast on a phone as on a computer; the PDF is saved to your Downloads folder.
