The HTML to PDF library delivers high-performance APIs to convert web content into PDF documents programmatically. This performance benchmark report highlights the speed and efficiency of HTML-to-PDF conversion, showcasing how the library manages large-scale document rendering in real-world scenarios.
Environment Details
The following system configurations were used for benchmarking:
OS Edition : Windows 11 Enterprise
Version : 22H2
Processor : 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz 2.42 GHz
Installed RAM : 20.0 GB (19.7 GB usable)
System type : 64-bit operating system, x64-based processor
Example Application
The benchmark details were obtained using the Syncfusion.HtmlToPdfConverter.Net.Windows package. You can refer to the following sample, as well as the input and output files used:
Input HTML files : Input HTML files
Output PDF files : Output document
Results
| Input Page count | Conversion time (Avg value of 5 conversions) | Process Memory and CPU usage |
|---|---|---|
| 10+ Pages | 2.78 seconds | Memory usage: 318 MB CPU usage: 10% |
| 100+ pages | 3.65 seconds | Memory usage: 367 MB CPU usage: 14% |
| 1000+ pages | 6.72 seconds | Memory usage: 813 MB CPU usage: 27% |
| 10 documents with 100+ pages in a loop | 30.52 seconds | Memory usage: 663 MB CPU usage: 15% |
| 10 documents with 1000+ pages in a loop | 1 minute 10 seconds | Memory usage: 2.2 GB CPU usage: 64% |
NOTE
The performance metrics were recorded on a freshly configured machine. Speed and memory usage may vary if the machine is running other processes. Additionally, performance can be affected by:
- External resources loaded in the HTML (such as images, scripts, and styles)
- Network speed for online URL conversions
- Hardware resources (CPU and memory)
