Online PDF conversion tools allow you to convert a wide range of files (text document, images, spreadsheets, presentations, databases, etc.) into a PDF document. All at no expense and without downloading any software or plug-ins to your computer.
Until a few years ago, the only way you could create a PDF file was by purchasing Adobe Acrobat Pro, but in recent times, several free solutions to create PDF have become available.
The characteristics that make PDF files great for creating and sharing your documents are renowned, but in case you are wondering what are these advantages, in the list below there are the major ones:
- Platform-independent: Font, text styles, images and the layout of your text look exactly the same no matter what operating system or software you are using to view a PDF document.
- High-quality: PDF quality is much higher compared to other similar formats. A PDF usually looks just as a printed sheet.
- Secure: A PDF can easily be password-protected to prevent unauthorized access, copy or print of your content.
- Virus-free: PDF files cannot be infected by viruses, trojans or malwares. You can spread your work safely.
- Open: PDF is an open format which means the PDF file format can be used and implemented by anyone, completely royalty-free.
As previously stated, these free online PDF conversion tools allow you to convert an existing file into PDF, but you cannot edit the converted PDF once the document has been generated. To really evaluate if these PDF conversion tools are what you are looking for, here are some of the things you cannot do:
- Edit page numbers,
- Re-arrange the layout of the text,
- Adjust the zoom factor to select exactly how the PDF will open on the screen,
- Create hyperlinks,
- Add images, videos, audio tracks or any other type of media content.
How do these PDF conversion tools work? Generally, all you have to do is upload a file from your computer and provide your e-mail address to receive the converted PDF. If permitted, you can also protect your PDF with a password, add a watermark, customize the output quality of your PDF, and more.
Let's look now into some of the key features and traits that characterize these online PDF conversion tools:
- Web-based: PDF documents are converted without the need to download or install any software. you can use any type of computer or operating system.
- Document Fidelity: Original formatting, fonts, text styles, hyperlinks and images included inside your original file are fully preserved during conversion to PDF.
- E-mail delivery: Converted PDF documents are delivered to an e-mail address of your choice in a matter of minutes.
I have also prepared a set of comparative tables and individual reviews to compare all of these PDF conversion tools. The comparative criteria I have selected include:
- Supported formats: File types supported by online PDF conversion tools.
- Conversion by URL: Conversion into PDF of an existing document published on the web.
- Watermarking: Inclusion of a text overlay with critical information like "Confidential" or "Important" inside your PDF.

- Compression quality control: Settings to customize the output quality of your PDF document.
- Delivery method: Download of your converted PDF document right after the conversion or by having an e-mail message sent to your inbox.
