PDF and HTML files are the two main popular formats for digital documents. Both have their own strengths and weaknesses, so it's important to choose the right format for your needs. PDFs are generally better for documents that need to be printed or shared offline. This is because formatting and layout are maintained wherever you view them. On the other hand, HTML documents are designed to be viewed online and can be easily edited and updated. They also usually take up less space than PDFs. So which format should you use? If you need documents that look professional and can be easily printed or shared offline, PDF might be your best bet. However, if you need a document that can be easily edited or only viewed online, HTML might be a better choice.
