HTML to PDF Conversion Made Simple: Tips, Tools, and Best Practices

Eric -

Introduction

In today's digital world, PDF is the most widely used file format for sharing documents online. PDF files are popular because they preserve the formatting and layout of a document, making it easier for users to read and share. However, creating a PDF file from an HTML document can be challenging, especially if you don't have the right tools. This article will discuss HTML to PDF conversion and how to convert HTML files to PDF quickly and efficiently using various tools, including cloudlayer.io.

Understanding HTML to PDF Conversion

HTML to PDF conversion is converting an HTML document into a PDF file. HTML (Hypertext Markup Language) is used to create web pages. It is a text-based language that describes the structure and content of a web page. On the other hand, PDF (Portable Document Format) is a file format developed by Adobe Systems that captures document formatting and enables file sharing.

HTML to PDF conversion can be useful in several scenarios. For example, you may want to create a PDF version of a web page for offline reading, or you may want to convert an HTML-based report into a PDF file for easier sharing. HTML to PDF conversion can also be used to create invoices, receipts, and other documents.

Using cloudlayer.io

To use cloudlayer.io for HTML to PDF conversion

  1. Sign up for an account.
  2. Create your template with the template editor.
  3. Get your API Key
  4. Create your PDF Template using our Template Editor.

The Template to PDF API call lets you create a Template in HTML and pass in variable data to reuse that template over and over. If you want to use HTML and not a template we also support that, as well as URLs.

You can use curl to call our API like follows, or any REST API Client like Insomnia.

curl --request POST \
  --url https://api.cloudlayer.io/v2/template/pdf \
  --header 'Content-Type: application/json' \
  --header 'x-api-key: <your-api-key>' \
  --data '{
	"templateId": "<id-of-your-template>",
	"async": false,
	"data": {
		"name": "test"
	}
}'

cloudlayer.io also supports reusable PDF templates, which lets you create your HTML document once, put placeholders in it using the Nunjucks templating language, and using variable data to generate PDF documents from the template. This allows for significantly more flexibility and ease of use since you can simply re-use your HTML over and over and have PDF documents with consistency.

We also have a builtin template editor, with syntax highlighting, error checking, and quick preview to see changes you make in real time. If you need to make a change to your template, open it up in the template editor, make the change and all of your new PDF documents will reflect the change immediately.
