HTML and PDF are both considered universal formats. Web browsers and computers across all platforms can support them. Also, they are both easy to circulate and transmit by e-mailing or publishing online. Yet, while both are very similar, there are notable and important differences.
A simple case in point: you have online receipt and need a record of it, but cannot it print up at the moment.
In such a situation, you will definitely need a few features which a webpage or HTML format lacks. You cannot preserve the formatting in most cases, nor can you apply security restrictions such as passwords or permissions to protect your data.
Converting from HTML to PDF will allow you more options with your content, including security and saving options.
Here is how you can go from HTML to PDF by simply using a browser like Chrome and Adobe Acrobat 11 Pro.
Depending on your needs, you may find that converting HTML to PDF is, indeed, the better option. Not only will it be viewable across all platforms exactly as you saved it, but you can also ensure that your information is secured.
