When you have a single HTML document, conversion is easy. You take the nearest online PDF converter and convert the web page to PDF. Everything gets more complicated when you process hundreds or thousands of documents daily. For example, you are a web platform owner and need to provide users with automated PDF reports.
The thing is, bulk document generation entails many issues. You need to implement more complex rendering automation, ensure personal data confidentiality, and keep formatting and other nuance in mind.
If anything goes wrong during large-scale conversion, heaps of documents will have mistakes. All of your customers won’t be able to generate reports. Your archives will fail to store the document copies, which will affect compliance.
To avoid the consequences of poor bulk conversion, you should be aware of the possible issues from the start. Our article will explain how to change HTML to PDF error-free and troubleshoot with an API PDF generator.
What Is So Challenging About Bulk HTML to PDF Conversion?
First of all, the cost of mistakes is much higher. Converting one document, you can always use a PDF template editor to fix inaccuracies. Despite taking some extra time, it’s an easy way to get the desired document format and content.
When it comes to bulk document generation, you won’t be able to manually edit every file. Moreover, you may even fail to notice mistakes since there are too many documents. To properly process tons of HTML to PDF files, you will have to set up programmatic document generation. The configuration of rendering software may be challenging. You will need to set up conversion rules, keep the formatting, and mind other issues.
Six Most Common Issues with At-Scale HTML to PDF Conversion
The most frequent issues when you generate PDF documents stem from automation, accuracy, and security. These factors are essential to have quality PDF pages that include the right content and formatting.
Lack of Comprehensive Automation and Interoperability
Even though you can process PDFs in batches, comprehensive automation is the demand of the future. For businesses that generate PDF documents on a large scale, rendering is based on different triggers and happens within a multi-factor process. For example, PDF invoices are automatically created from HTML to deliver monthly emails, display documentation in real time, store records, and more. They also combine data from several sources and tools.
That’s why making rendering software a part of other automated processes is a real challenge. To set it up, you will need to connect multiple solutions with high interoperability. Without synchronizing all of the processes related to document rendering, you won’t fully automate HTML to PDF creation.
Big Data Processing and Storage
When PDF converters process documents at a large scale, they must be capable of handling big data. Bulk HTML to PDF rendering involves a lot of information and can overload systems with limited capacities. It will result in PDF rendering crashes and slow down business operations.
Therefore, instead of on-premise solutions, it’s better to choose cloud-based PDF generators. A third-party provider will take responsibility for storage maintenance and tailor the offered capacities to your needs.
Confidentiality and Access Limitation
When you process large volumes of documents, you become particularly vulnerable to data breaches. Security is a big deal in document rendering. HTML to PDF rendering is often about creating documents with highly confidential information. These are healthcare reports, bills, invoices, analytics reports, financial statements, etc. Such documents include names, surnames, address details, financial information, and other data that require ultimate security. By compromising bulk rendering, attackers instantly get access to thousands or millions of private records.
How to change HTML to PDF free of errors and securely? Mind user roles and data confidentiality. Only limited access to rendering functionality can protect you from data leakage.
HTML to PDF Page Size and Formatting
Formatting is always an issue when you render one file to another. Converting HTML to PDF, you risk losing the right page margins, headers and footers, width and height, page orientation, page numbers, and PDF page size. As a result of the HTML to PDF page size and other losses, the final file won’t look as expected. And when you handle tons of different documents, the risk of formatting mistakes is huge.
To avoid such issues, you will need a REST API PDF generator that configures HTML files before conversion. Then, you will be able to customize HTML to PDF page size, margins, orientation, and other details to create PDFs with the desired style.
Original HTML pages have metadata information that may get lost after rendering. With it, businesses start missing crucial details about file authors, content, and history. When you process thousands of documents, such details are critical. They help to trace interactions with a specific document as well as filter existing documents by multiple parameters.
Tables and High-Resolution Images
Not all API PDF generators and web browser rendering tools can handle high-resolution images. You will need a tool that supports TIFF and SVG formats. Otherwise, the PDF images may be gritty or not renderer at all. Tables are also tricky as they often get distorted or omitted during conversion. Such troubles severely affect the quality of HTML to PDF rendering.
Besides, documents with many additional elements can take more time to convert. If you need to process many of them at once, it will overload your system and lead to errors.
How an API PDF Generator Simplifies Bulk Conversion
An API PDF generator is the best alternative to a custom solution developed for your business needs. It takes less time to integrate and is much cheaper. An API PDF generator is also better than online document converters that require you to manually upload HTML batches to obtain PDFs. Online tools fail to convert high-resolution images and tables, cannot keep the proper HTML to PDF page size, and distort formatting.
You can integrate an API PDF generator with your existing software solution to automate rendering. It becomes an indispensable part of your system and ensures outstanding interoperability.
API PDF generators also help to avoid other common rendering issues with the following capabilities:
- An API PDF generator is easy to automate and allows generating documents programmatically;
- An API PDF generator, like Render, supports high-resolution image formats and flawlessly convert tables;
- An API PDF generator provides cloud-based document processing and storage, so you don’t need to maintain it;
- An API PDF generator supports extensive HTML to PDF conversion formatting capabilities and API calls types.
