Ghostscript vs wkhtmltopdf: What are the differences?

Introduction

In the realm of converting documents to PDF, two popular tools that often come into play are Ghostscript and wkhtmltopdf. These tools offer distinct features and functionalities, making them suitable for different use cases. In this analysis, we will explore the key differences between Ghostscript and wkhtmltopdf, highlighting their unique characteristics and abilities.

Rendering engine: Ghostscript utilizes the PostScript and PDF interpreter engine, allowing it to process and convert PostScript and PDF files effectively. It excels in handling complex vector images, advanced typography, and intricate page layouts. In contrast, wkhtmltopdf employs the WebKit rendering engine, which primarily focuses on converting HTML to PDF. This makes it an ideal choice for tasks involving HTML-based documents, including web pages, online reports, and dynamic content.
Input format flexibility: Ghostscript exhibits tremendous versatility in terms of input format compatibility. Alongside PostScript and PDF, Ghostscript can process various file formats such as TIFF, JPEG, PNG, PBM, and PCL, among others. It can even capture files directly from input devices, like scanners. Conversely, wkhtmltopdf specializes in HTML as its primary input format, allowing seamless conversion of HTML documents into PDF. It might lack the same level of flexibility when it comes to handling other input formats.
Customizability and control: Ghostscript empowers users with extensive customization and control over the conversion process. It provides a wide array of command-line options, allowing users to fine-tune the conversion parameters, output quality, compression settings, color management, and much more. This level of granularity caters to advanced users seeking full control over their PDF generation. In contrast, wkhtmltopdf, being designed for simplicity and ease of use, offers limited customization options. While it still provides some configuration possibilities, it may not satisfy the specific needs of highly specialized use cases.
Dependency on external tools: Ghostscript operates as a standalone tool and does not require any dependencies from other software. It has its self-contained interpreter, making it more convenient for installation and usage. On the other hand, wkhtmltopdf depends on external tools such as a working installation of the Qt framework and WebKit libraries. This reliance on additional components may introduce complexities during the setup process and could pose compatibility issues, especially in environments where these dependencies are not readily available.
JavaScript execution: One significant distinction between Ghostscript and wkhtmltopdf lies in their JavaScript execution capabilities. Ghostscript primarily focuses on the rendering and conversion of static PDF and PostScript documents, providing minimal JavaScript support. However, if the need arises to convert HTML files with complex JavaScript interactions, wkhtmltopdf can better handle such scenarios, thanks to its WebKit engine. This makes it suitable for producing PDFs that faithfully replicate the behavior of interactive web pages.
Licensing and community support: Ghostscript is released under the GNU Affero General Public License (AGPL) and benefits from a large and active open-source community. This grants users access to numerous resources, documentation, forums, and potential support channels. Conversely, wkhtmltopdf is distributed under the GNU Lesser General Public License (LGPL) and enjoys significant community support as well. However, it is worth noting that some commercial activities may require additional licensing or agreements, further emphasizing the importance of understanding the licensing implications for individual use cases.

In summary, Ghostscript and wkhtmltopdf offer distinct features and suitability depending on the requirements and nature of the task at hand. Ghostscript excels in handling complex PostScript and PDF files, while wkhtmltopdf specializes in HTML-to-PDF conversions, with a focus on web content and dynamic interactions. The choice between these tools should be made based on factors such as input formats, customization needs, JavaScript requirements, and licensing considerations.

Advice on Ghostscript, wkhtmltopdf

Needs advice

Users are uploading huge PDF files of more than 100MB on our platform. We are creating several tools to manage those files, but keeping the raw file will eat up space, as we are handling several of them. After upload, they will be mainly keep stored for future use.

I am looking for a tool to compress and optimize those PDFs, like a library or an external API that can process that for us.

Thanks
