With the development of the Internet, more and more content is circulated on the Internet, and HTML, as one of the most mainstream web page production languages, has also become the main expression method of Internet content. As HTML content increases and becomes richer, how to save or share it with others has become an important issue. The PDF format is currently a widely used file format that can maintain the original page format and layout, so converting HTML to PDF has become a practical need.

There are many ways to convert HTML to PDF. This article will mainly introduce several common methods for readers' reference.

1. Use the printing function that comes with the Chrome browser

The Chrome browser has a very powerful printing function. Through its printing function, you can directly save HTML web pages into PDF format documents. The specific implementation method is as follows:

  1. Open the HTML webpage that needs to be converted in the Chrome browser;
  2. Move the mouse to the menu icon in the upper right corner and select the "Print" option;
  3. In the pop-up print settings window, select "Save as PDF" in the "Target Printer" column;
  4. Adjust the print settings according to personal needs, such as setting page size, margins, etc.;
  5. Click the "Save" button to save the HTML web page as a PDF document.

This method is simple, efficient, free, and has the advantages of good compatibility, but the disadvantage is that it requires the support of the Chrome browser. At the same time, since the implementation of this method requires rendering HTML web pages and generating documents in PDF format, when the web pages are too complex or have too much content, problems such as confusing layout or slow reading speed of the generated PDF files may easily occur.

2. Use third-party software tools

In addition to the browser's own printing function, you can also use some specialized software tools to convert HTML to PDF. Among such tool software, the more common ones include Adobe Acrobat, PDFcreator, etc.

Taking PDFcreator as an example, the specific implementation method is as follows:

  1. Install the PDFcreator software on the computer;
  2. Open the HTML webpage that needs to be converted in the browser;
  3. Click the "Print" function in the browser and select "PDFcreator" as the printer;
  4. Set according to personal needs, you can set the target file name, file storage location, file format, etc.;
  5. Click the save button to generate a document in PDF format.

Compared with the browser's own printing function, this method is generally more stable and reliable, and can convert more complex web content. However, it also has some shortcomings, such as software installation requiring space, and some software may require payment.

3. Use online conversion tools

In addition to local software tools, you can also use some online conversion tools to achieve HTML to PDF conversion. Taking HTML2PDF of niche software as an example, the specific implementation method is as follows:

  1. Open the HTML2PDF webpage of niche software in the browser;
  2. Fill in the address of the HTML webpage that needs to be converted. Enter the input field of the web page;
  3. Set some options (such as header, footer, page number, etc.) according to personal needs;
  4. Click the "Generate PDF" button to convert the HTML web page into Document in PDF format.

This method does not require the installation of software, is highly portable, and most online tools can be used for free, but it also has some limitations, such as browser compatibility, conversion speed, etc.

4. Use programming languages ​​such as JavaScript to achieve conversion

Converting HTML to PDF can also be achieved by writing code, taking the use of JavaScript as an example. By using third-party JavaScript libraries (such as html2pdf.js), you can easily convert HTML web pages to PDF files.

The implementation of JavaScript code can be simply divided into the following steps:

  1. Introduce the html2pdf.js library file;
  2. Get the DOM node of the HTML web page that needs to be converted , and embedded into the corresponding elements provided by html2pdf.js;
  3. Call the API of the html2pdf.js library through JavaScript code to generate and save PDF files.

This method has the advantages of high flexibility and customizability, and at the same time, you can freely choose the coding language and tools. However, it also requires high programming ability and time cost, and it does not rule out the problem that it cannot be converted or generated normally.

To sum up, there are many ways to convert HTML web pages to PDF format, and each method has its own advantages and disadvantages. Readers can choose the method that suits them best according to their needs and actual situations in order to better save, share or read HTML web content.
