Convert IDF files online for free
The converter easily converts your IDF file to various formats - free and online. No Excel or extra software needed.
The converter also works in reverse, so you can convert other Cad formats to IDF with high quality output.
The .IDF extension is shared by several technical formats, most notably the Intermediate Data Format used in electronics engineering and the EnergyPlus Input Data File for building simulations.
In the context of printed circuit boards (PCBs), IDF files serve as a bridge between ECAD (electronic layout) and MCAD (mechanical design) systems. While critical for collaboration, IDF files are inherently limited: they are often simple ASCII text files that define board outlines and component coordinates but lack embedded 3D geometry. This means opening an IDF file in software like SolidWorks or AutoCAD often results in 'blocky' representations unless paired with a local 3D component library. Similarly, EnergyPlus IDF files contain complex text-based building parameters that are difficult to visualize without specialized engines.
For engineering workflows, users typically need to convert PCB IDF files to STEP or IGES formats to create fully realized 3D assemblies for interference checking. For documentation or archiving, converting these technical text files to PDF ensures the data remains readable without proprietary software like Altium Designer or NiceLabel.
Use Convert.Guru to open and convert your IDF file.
Users also converted LDF, IDFH, IFD, EMN, IDT, PDF, JPG, PRO, DOCX, ZIP, CSV, TIF and DWF files.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our IDF converter.
