What happens when you convert DOCM to PDF
- The DOCM is opened by LibreOffice, the open-source office suite, on our conversion server and exported to PDF with its layout: text, fonts, images, tables, headers, footers and page breaks.
- Macros are never run. PDF cannot hold VBA macros, so they are left out; everything else converts normally.
- Where the file uses a font our server does not have, a metric-compatible one is used instead: Carlito for Calibri, Caladea for Cambria and Liberation fonts for Arial, Times New Roman and Courier New, so lines break where they did. Unusual or decorative fonts may look different.
- Password-protected files cannot be converted, because they cannot be opened without the password.
- 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 DOCM to PDF online
- Press "Choose DOCM 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 DOCM and the PDF by then.
Why convert DOCM to PDF?
DOCM files usually come from Word documents that automate forms and reports with macros. 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, DOCM 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. DOCM opens in Word, which asks before running its macros; LibreOffice and Google Docs open the text, while PDF opens in every browser's built-in viewer.

About DOCM and PDF files
What is a DOCM file?
A DOCM is a DOCX that is allowed to carry VBA macros. Word gives it its own extension so a document that can run code is easy to spot, and many email systems block DOCM attachments for that reason.
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.
DOCM 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.
- The file will not convert. It may be password protected, damaged, or saved in a newer or unusual version of the format.
Convert DOCM to PDF from the command line
LibreOffice does the same on your own computer, without opening a window:
soffice --headless --convert-to pdf input.docmConverting 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.
DOCM to PDF converter FAQ
Will I lose quality converting DOCM to PDF?
The PDF looks like the DOCM printed: text stays sharp and selectable, and images keep their resolution. Fonts our server lacks are replaced with close equivalents, which can change the look of unusual fonts.
Why is the PDF a different size from the DOCM?
A PDF embeds the fonts and images it uses, so it may be larger or smaller than the DOCM depending on its pictures. Text-only files usually make small PDFs.
Are my DOCM files uploaded?
Yes, for this conversion. A faithful DOCM to PDF conversion needs LibreOffice, the open-source office suite, 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 DOCM 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 DOCM 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 DOCM 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.
