What happens when you convert EMZ to PNG
- The EMZ is unpacked on our conversion server, because it is an EMF drawing compressed with gzip, and the EMF inside is opened by Inkscape, the open-source vector editor, and saved as a PDF, and MuPDF draws it at 300 dpi, so a drawing 10 cm wide becomes about 1,180 pixels wide. The longest side is capped at 6,000 pixels.
- The drawing is placed on a white background, so the PNG has no transparency.
- PNG is lossless, so lines and text stay exactly as crisp as they were drawn.
- 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.

About EMZ and PNG files
What is an EMZ file?
An EMZ is an EMF drawing compressed with gzip. Office stores pictures this way, and a web page saved from Word or PowerPoint comes with a folder of image001.emz files, which is where most EMZ files people want to open come from.
What is a PNG file?
PNG compresses without losing a single pixel, so screenshots and text stay razor sharp, but a photograph saved as PNG is often three to five times the size of the same photo as JPG.
EMZ to PNG 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 EMZ format." The converter checks every file before it runs anything, so a file of another format renamed to .emz is refused. Choose the page for its real format.
Convert EMZ to PNG from the command line
gzip and Inkscape do the same on your own computer:
gunzip -c input.emz > input.emf
inkscape input.emf --export-type=png --export-dpi=300 --export-background=white --export-filename=output.pngConverting 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.
EMZ to PNG converter FAQ
Will I lose quality converting EMZ to PNG?
The drawing is rendered to pixels at 300 dpi, sharp for print at its own size. The pixels are stored losslessly.
Why is the PNG a different size from the EMZ?
The PNG stores every pixel, so it is usually larger than the EMZ, which stores drawing commands.
Are my EMZ files uploaded?
Yes, for this conversion. A faithful EMZ to PNG conversion needs Inkscape and MuPDF, two open-source tools, 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 PNG as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several EMZ files to PNG 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 PNG file?
PNG opens in every browser and image viewer. PNG is common for screenshots, logos, diagrams and anything with transparency.
Is this EMZ to PNG 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 EMZ to PNG 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 PNG is saved to your Downloads folder.
