I tried it and immediately fell in love! It was so easy to use! After a couple conversions I bought the guys a cup of coffee. A couple more and decided this was too good to abuse! I joined! My life is so much easier!


I had a huge, problematic file to convert that couldn't go through the usual automated conversion process. The Zamzar team responded quickly to my request for help, and they took the extra steps needed to do it manually.


Used it for over a year to convert my bank statements to csv files. Great quick app, increased my productivity a lot. Also, amazing support - always helped me quickly!

I've used this product for years. And customer service is excellent. Just had an issue where I was charged and I didn't agree with the charge and they took care of it, even though they didn't have to.


A very useful and professional site. The service is easy to use and the administrators are helpful and courteous.

David Shelton

It’s my first time using it. I had some complications doing it. I’m not very good at this. But I wrote to the company and I had a lot of help. I’m satisfied with customer service and with the app.

Ana Suárez

Great for when you need a lot of conversions in a short time. You have directly access and can even put the subscription on for just a month.

Sabina Calis

Great thanks to you all for helping me to get the OLD files converted correctly. 20 years, quite a long time, reviewing the files brings much memory to me. That's the best gift I received last year. Thank you all again.

I feel like Zamzar is an active team member, especially for projects that I work on where I am the workhorse and it saves so much time and frustration. I am spoiled with Zamzar, because they have set the bar for file conversion and customer service very high.

Deborah Herman

Fantastic service! My mom's computer died and she has 1000+ Word Perfect files she wants to keep for some reason. Since Word Perfect is basically dead, I decided to convert all her files. Zamzar's converter was perfect.

DOCX Document Format

DOCX Converter

The DOCX format has been the standard format for Microsoft Word documents since 2007, replacing DOC. Microsoft Word is used widely in homes, workplaces and educational settings to create formatted text documents like reports, letters or resumes. As well as text, DOCX files can include pictures, tables, charts and embedded media, or can be an editable template.

The DOCX format has some advantages over DOC, including typically smaller file sizes and better security. DOCX is an Office Open XML file, making it easier to open DOCX files in other programs like LibreOffice, Google Docs or Apple Pages, with fewer compatibility issues. Word is part of Microsoft Office’s paid software application and is also available with an Office 365 online subscription. Microsoft Office was designed for Windows, but you can install Office apps on other operating systems. Microsoft also has a basic free ‘Word for the web’ programme for online Microsoft account holders.

PDF Document Format

PDF Converter

PDF stands for ‘Portable Document Format’ file. It was developed by Adobe so people could share documents regardless of which device, operating system, or software they were using, while preserving the content and formatting. The format has evolved to allow for editing and interactive elements like electronic signatures or buttons. The PDF format is now a standard open format that isn’t just available under Adobe Acrobat. It is maintained by the International Organisation for Standardization (ISO).

PDF files aren’t typically created from scratch, but are usually converted, saved or ‘printed’ from other documents or images before sharing, publishing online or storing. They can be viewed on almost all devices. Creating a PDF can involve compressing a file, making it take up less storage space. You would typically create a PDF if you wanted to ensure document fidelity, to make it more secure, or to create a copy for storage.

Frequently asked questions

If you’ve got any questions about converting or compressing files with Zamzar, we’re happy to help! We’ve answered a few commonly-asked questions below, to get you started, and you can find out more information about file conversion and compression with Zamzar, in our Help centre.

You can convert a DOCX to PDF using Microsoft Word or a conversion tool. To use Word, simply open your DOCX file within the application, click ‘File’, ‘Save As’ and then select PDF as the format to save to. You will be able to select a location on your device to save your new PDF file to. If you have older versions of Word you may not be able to convert to PDF, in which case you will need to use a conversion tool such as Zamzar, to save your file as a PDF. Zamzar’s 3-step process walks you through how to convert your file; it’s quick, simple, and free!

If you don’t have Microsoft Word on your device, you can convert a DOCX file to PDF using a conversion tool. Zamzar’s online conversion tool is free to use and has a simple interface which walks you through the step-by-step process of converting your file. Upload, convert, and download your PDF file in seconds - all from the same page.

Alternatively, you could download and install LibreOffice Writer, and use this to open your file and export it as a PDF. You would need to manually convert each file one at a time, so Zamzar would be a quicker solution if you have several files to convert.

Aside from the fact that DOCX and PDF are created by two different companies and used for different purposes (DOCX was created by Microsoft for their Microsoft Word application, whereas PDF files were created by Adobe Acrobat), the main differences between DOCX and PDF are their methods of delivering content, and ability to edit content within the files. PDF files are typically used to view content - they’re ideal for sharing documents in a format that restricts others from editing the file. On the flip side, Word-based DOCX files have greater functionality to create and edit content and they are fairly compact in size. You can easily convert between DOCX and PDF using Zamzar’s free online tool.

You can convert a DOCX file to PDF on your laptop using apps such as Microsoft Word, a cloud-based option such as Google Drive, or using an online converter such as Zamzar. To use Microsoft Word, ensure your DOCX file has been opened within the app, then click to save the file as a PDF from the list of options. To use Google Drive, you can upload your DOCX file to the cloud, then opt to export the file as a PDF. To use Zamzar, simply go to the website’s conversion tool and follow the three-step instructions, then download your file from the same page.

You can convert DOCX to PDF on your phone using an online converter or, if you have the app downloaded, using Google Drive’s ‘Print’, then ‘Save as PDF’ option. Zamzar’s online converter enables you to convert a DOCX file to PDF through a browser (e.g. Chrome or Safari); simply go to our website and follow the three-step process on screen to quickly convert your file. Once the conversion is complete, you can download the PDF file from the same page.
