17 Best Online PDF Readers and Editors in 2020 [100% Working]


Despite being around for more than 25 years, PDFs are still one of the most popular types of documents available on the internet. Whether you’re accessing your e-book, resume, or a contract, the PDF is the most convenient and sleek format. However, you may need to download a PDF reader on your smartphone and PC so you can view or edit PDF documents without any issues. The most notable aspect of PDF documents is that their format and content don’t change regardless of the type of PDF reader or device you are using.

On the contrary, the main drawback is that there aren’t many options when it comes to free PDF editors. Since the original developer of the PDF format is Adobe, some PDF-focused software require fees to edit PDF documents. The majority of them can read and save PDFs but not edit them.
