For complex projects, QET includes professional-grade features:
⚠️ Avoid third-party sites; only use the official source for security.
The software includes a massive built-in library of standard electrical symbols (IEC, ANSI). The portable version allows you to maintain a local "User Library" inside the application folder, ensuring your custom symbols travel with you. Intelligent Conductor Routing
Are you trying to fit a large industrial diagram onto a single page, or do you need to split it across multiple sheets?
For those unfamiliar with the base software, QElectroTech is an open-source application designed specifically for drawing electrical diagrams. Unlike general-purpose vector graphics software (like Inkscape or Visio), QElectroTech is built with electricians in mind. It features:
Automated generation of terminal blocks and bills of materials (BOM). What Makes the Portable Version Different?
One of QElectroTech's strongest assets is its extensive built-in component collection. The software includes thousands of symbols covering electrical, pneumatic, hydraulic, logic, and fluid systems. This library continues to grow with each new release, thanks to an active and dedicated user community.
While the primary portable version is for Windows, the underlying software is a testament to cross-platform design. Files created on the Windows portable version can be opened and edited seamlessly on a macOS or Linux system running QET, and vice versa, with no conversion needed. Linux users can also enjoy a portable experience using AppImage packages, making the portable philosophy universal across operating systems.
: Includes over 8,000 symbols (elements) for electrical, logic, and fluid systems.
: Includes a vast collection of standardized symbols (IEC, ANSI) for electrical, hydraulic, and pneumatic circuits.
QElectroTech Portable is the portable version of the standard QElectroTech. It does not require any installation at all. You can copy the program files to any location on your hard drive and run it by simply double-clicking the executable file. Better yet, you can place it on a USB flash drive and take the entire program with you, running it on any PC you have access to. This version leaves no traces behind—no files are added to your hard drive, and nothing is written to the Windows registry.
is the fully functional, zero-installation version of the popular QElectroTech desktop application. It allows electrical engineers, students, and automation technicians to design electrical diagrams, piping and instrumentation diagrams (P&ID), and fluid circuits on any Windows computer without administrative privileges.
