How to convert html to pdf

With the development of technology, our working methods are becoming more and more digital and convenient, and one of the inevitable problems is the conversion of document formats. For example, when we edit an HTML file, we may need to convert it into PDF format for sharing, printing or long-term storage. This article will introduce some common methods of converting HTML to PDF and explore their advantages and disadvantages.

1. Use the printing function that comes with the browser

For simple HTML file conversion, we can directly use the printing function that comes with the browser. Just open the HTML file, select "File-Print" in the menu bar, and then select "Save as PDF". This method is simple to operate and does not require extra tools. The disadvantage is that browsers with built-in printing functions can often only save single-page PDFs. If the HTML file is complex or contains multiple pages, it requires multiple printing and merging of PDF files, so it is not suitable. For batch processing of large amounts of documents.

2. Use HTML to PDF library

In addition to the browser’s own printing function, there are many third-party libraries that can be used to convert HTML files to PDF format, such as wkhtmltopdf, WeasyPrint, etc. . These libraries render HTML pages and simulate printer output for PDF export. Among them, wkhtmltopdf is the most famous HTML to PDF library. It can not only output high-quality PDF documents, but also supports advanced functions such as font embedding, page splitting, and multi-file merging. However, this method requires understanding some programming skills and installing corresponding libraries and dependencies. Some advanced features may require payment. Therefore, this method is suitable for professional users who need to batch process a large number of documents.

3. Use online conversion tools

If you don’t want to download any software or don’t know how to program, then online conversion tools are a good choice. Currently, there are many online HTML to PDF tools that provide free services, such as pdfcrowd, HTML To PDF, etc. These tools are usually based on cloud rendering engines. By passing in the URL or text content of the HTML file, the corresponding PDF file can be obtained. The advantage is that there is no need to install any software, the entire process is online, and it supports batch processing and some advanced features, such as custom headers and footers, watermarks, etc. However, this method must ensure the security and privacy of the uploaded HTML files, and will be affected by factors such as network speed and server performance.

4. Use plug-ins

In the browser, there are many plug-ins for converting HTML to PDF, such as Print Friendly & PDF, Save as PDF, etc. These plug-ins can convert pages into PDF format directly in the browser. This method is relatively simple and convenient to operate, but it requires downloading and installing plug-ins and relies on a specific browser, so it is not suitable for multi-platform use.

In short, converting HTML to PDF is a common work requirement, and with the continuous advancement of technology, we already have many different options to meet this requirement. Whether it is the browser's own printing function, the use of third-party libraries and online tools, or browser plug-ins, each has its own advantages and disadvantages. Therefore, we can choose the most suitable tool to convert HTML to PDF based on specific needs.
