Files with .drl extension are Gerber drill files. They contain drill data for manufacturing printed circuit boards. The .drl file format follows the Gerber specifications standard. The files include data on the drilling tools and drill sizes used.
To open .drl files, you need an application that supports this format. Some options are Altium Designer, FreePCB, Pentalogix ViewMate on Windows. On Mac and Linux, the Cenon software can create and edit .drl files.
If you have issues opening a .drl file, ensure the file is complete and error-free. If the file was from a third-party, request an intact copy. An incomplete download can cause issues accessing the data. You may also need administrative rights on your system to open .drl files correctly.
Our free online .drl file viewer needs no registration or installation. It is a custom tool allowing you to open and view .drl files from any modern browser. All files are processed securely on our servers and removed automatically within 24 hours.
