What happens when you convert WMZ to PDF
- The WMZ is unpacked on our conversion server, because it is a WMF drawing compressed with gzip, and the WMF inside is opened by Inkscape, the open-source vector editor, and saved as a PDF page the size of the drawing.
- Shapes and text stay vectors, so the PDF is as sharp as the metafile at any zoom, and it opens in every browser and on every phone.
- Windows metafiles can contain features Inkscape does not draw exactly, such as some fonts and hatch patterns, so check the result against the original.
- 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.
How to convert WMZ to PDF online
- Press "Choose WMZ files" and select one or more files, or drag them onto the box. Files up to 25 MB each can be converted.
- There are no settings to choose: the converter keeps everything the target format can hold.
- 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 WMZ and the PDF by then.
Why convert WMZ to PDF?
WMZ files usually come from pictures inside older Office documents and web pages saved from them. 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, WMZ 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. WMZ does not open in browsers; Word, PowerPoint and LibreOffice show it inside documents, while PDF opens in every browser's built-in viewer.

About WMZ and PDF files
What is a WMZ file?
A WMZ is a WMF drawing compressed with gzip, found in the image folders of web pages saved from Office. Windows Media Player skins also use the .wmz extension; those are ZIP archives of skin files and are not this format.
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.
WMZ to PDF not working? Common problems
- "Files up to 25 MB can be converted." Server conversions have a size limit. Compress the images inside the file, or split it, and try again.
- "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 WMZ format." The converter checks every file before it runs anything, so a file of another format renamed to .wmz is refused. Choose the page for its real format.
Convert WMZ to PDF from the command line
gzip and Inkscape do the same on your own computer:
gunzip -c input.wmz > input.wmf
inkscape input.wmf --export-type=pdf --export-filename=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.
WMZ to PDF converter FAQ
Will I lose quality converting WMZ to PDF?
Shapes and colours stay vectors, so nothing is lost to pixels. Each vector format supports a slightly different set of effects, so gradients, transparency and filters may be simplified.
Why is the PDF a different size from the WMZ?
Both store drawing instructions, so the PDF is usually of a similar size to the WMZ; embedded pictures make the biggest difference.
Are my WMZ files uploaded?
Yes, for this conversion. A faithful WMZ to PDF conversion needs Inkscape, the open-source vector editor, 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 WMZ 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 WMZ 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 WMZ 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.
