Did you know?

What does PDF mean?

PDF stands for Portable Document Format, a file format used to represent documents in a software, hardware, and operating system independent way. Developed by Adobe Systems in 1993, PDF is designed to retain its original appearance and format regardless of the device or software used to view electronic documents. PDF has also become the global standard for electronic document exchange due to its high security and ease of sharing documents both online and offline, and is widely used for sharing and printing important documents such as contracts, invoices, reports and other business documents.

What are the advantages of converting to PDF?

Working with PDFs is cheap.

You do not need to purchase expensive commercial programs like MS Office to view PDF files. You can easily find a free downloadable PDF reader for almost all commonly used operating systems. Additionally, PDF documents have the advantage of being digitally distributed almost free of charge.

PDF files can express the exact content.

PDF documents can be shared, viewed, and printed by anyone on any system, regardless of the user's operating system, application software, or fonts. With PDF, you can get the exact same representation of document content regardless of the computing environment. This means that you can view the same type of documents anytime, anywhere with just a computer or mobile device.

PDF documents retain all content properties.

The PDF document format can retain all the content information of the original document format, such as formatting elements, text structure, images, visual elements, and vector graphics. Even multimedia elements and features such as hyperlinks, markups, text notes, videos and music are preserved when converting to PDF, depending on options.

PDF makes it easy to secure digital documents.

By default, the PDF document format provides several methods of encryption, including password-protected viewing, copying, printing, and digital signatures. For important documents, you can digitally sign them to ensure original integrity. Recipients of these digitally signed PDF documents can verify that the documents have not been tampered with and that they are authentic.

PDF reduces the size of files without affecting the quality.

Converting graphics, spreadsheets, and word processing documents to PDF can significantly compress the file size. The PDF format is designed to significantly reduce document size while retaining the quality of the original document. This is especially important when viewing content with lots of small details, such as graphs and charts, and is useful when viewing content written in small font sizes that would otherwise be missed if not zoomed in. And because PDF files are smaller than original documents, they're easy to email and share. Businesses can also reduce the cost of maintaining expensive email server storage and bandwidth congestion.

Additional functionality of PDF increases work efficiency.

By default, the PDF format provides text search capabilities within the document, making it easy for users to find what they are looking for. For example, if you receive a work document with many pages, you can use the search function to search for a keyword or phrase to find what you are looking for. In addition, you can enter metadata such as title, author, and creation date into the PDF file. These meta data can be useful for distinguishing specific documents in large-capacity document management systems used by companies.


What do they say after use?


I like the simplicity of this site. Always easy to use and works very well. Love this site! Better than some charged software in the market. IMO, this is the best pdf conversion site among probably 20+ free services that I’ve ever tried. Great job, Onlinepdfconverter team!


This is a cool site. I was considering to buy Acrobat Pro, but I wasn’t sure whether I wanted to pay the price for all those fancy tools that I’d never use. Onlinepdfconverter is a perfect solution for me. I also recommended it to my colleagues. I hope this service remains free.


I’ve tried a few other free sites, and probably Onlinepdfconverter provides the most stable performance. Most other sites work ok for a simple conversion but provide limited functions or have other limits (e.g. free version allows only one job per 30 mins, etc.)

FAQs about our free online PDF conversion service

We have summarized the questions that may help you to solve any problem while you are using our pdf conversion service.

Do online services keep copies of my files after conversion?

No. We prioritize user security. Users' files on our servers are inaccessible to anyone and are strictly protected by multiple levels of encryption. Files are kept for up to 30 minutes, after which the files are permanently deleted from our servers. Users can complete the conversion and manually delete the document themselves. We do not scan, copy, or analyze files in any way, and we do not provide them to others or other companies or institutions.

Are there any basic system requirements?

Our PDF tools require a minimal system environment to run a web browser. If users want to run the tools more smoothly, we recommend working on the latest version of the browser such as Chrome, Firefox, Explorer +10, Safari. If a problem occurs on the download stage screen after operation, it is recommended to set the web browser to incognito mode and try again.

Are there any security issues with using online conversion services for company documents?

We prioritize the importance of privacy and security. All uploads on the service use HTTPS/SSL to protect your privacy and multiple levels of encryption protect your files so no one can access them. The file conversion process and deletion process are all done automatically in the cloud and are designed to leave no usage logs. This protection policy of our services enhances security and complies with the data privacy policies of most companies or institutions.

Why does the file conversion take so long?

Unfortunately, in most cases, this is not a problem we can solve. Document conversion processing speed is affected by a number of factors. For example, the file conversion speed will vary depending on the complexity of the uploaded file, the user's internet environment, and the server's instantaneous usage.

The document seems to have changed after converting the file. Why is that?

Does it look different from the original? Generally, this problem can occur when converting PDF files to MS Office documents. It's not common, but it happens occasionally. We are working to resolve issues related to this. Another reason could be the font used in the original document. This may happen if the font provided by Word on the user's computer is not supported by our website.

Are all services free?

Yes, it's free. It is a service that anyone can use for free, regardless of business, public institution, or individuals. All users do not need to purchase a separate license to use our service.

Do you log the activity of users visiting your web service?

No. Our web service by default does not ask for any personal information that could identify you. Anyone can use it anonymously without a separate sign-up process, and all processing is done automatically in the cloud. Designed with this philosophy, our web services do not store and track everything about your visited pages, uploaded documents, converted documents, and access information. Therefore, it is not possible to inform others, businesses, or institutions of this information.

How long does the free PDF conversion service last?

As long as our customers continue to love and use our services, we promise that our online PDF conversion service will be free forever. In addition, we will maintain the current policy that does not require membership, e-mail, phone number, and personal credit information when using the service.
