When importing PDF files into Eagle, you may sometimes encounter slow processing speeds. This article will help you understand the possible causes and provide solutions.

Main Causes of Slow PDF Import

File Size and Complexity: PDF files containing numerous graphics, layers, and high-resolution images may require longer processing time. For example, complex files of several dozen MB may take over 30 minutes to complete import, especially when the files contain extensive vector graphics or complex design elements.
Device Hardware Configuration: Your computer's processing power, memory, and storage speed directly affect PDF processing speed.
Software Version: Older versions of Eagle may use outdated parsing technology that cannot efficiently process certain PDF files.
Storage Location: If your Eagle library or PDF files are stored on NAS devices, network transmission and the read/write speed of storage devices may become bottlenecks.

Solutions
