What it does
Pelles C is a Windows desktop development kit for C, with an IDE and the tools needed to compile and build native applications. Its package includes an optimizing C compiler, assembler, linker, resource and message compilers, make utility, debugger, profiler and editors for Windows resources such as dialogs and menus. The official overview lists C99, C11, C17 and C23 support and targets across x86, x64 and ARM64, making it a specific fit for Windows-native C work rather than a portable general-purpose IDE.
Build and inspect a Windows C project
Pelles C includes both the editor and the compiler toolchain, so a Windows C developer can create or open a project, compile it, inspect execution in the debugger and manage Windows resources in the same kit. The product overview lists a linker, make utility, profiler and resource editors for dialogs, menus, icons, bitmaps and version information. It also documents support for C99, C11, C17 and C23, plus x86/x64 targets and an ARM64 configuration.
For example, a developer can create a small Windows program, build it with the included compiler and use the resource editor to add a dialog before stepping through the program in the debugger. This describes the documented components; no application was built or executed for this listing. Release 14.50 is listed for both x86 and ARM64 installers dated 2026-07-20, and its change notes include ARM64 debugger and NEON support.
Pelles C is freeware for personal and commercial use, and its terms say no registration is required to download it. Redistribution is allowed, but the program may not be sold. The current overview targets Windows 7/8/10/11 on x64 hosts and Windows 11 on ARM64 hosts, so check that target boundary before choosing it for another desktop platform.
Strengths
- The package includes its compiler, linker, assembler, make utility, debugger and profiler rather than requiring a separate IDE toolchain.
- The IDE includes editors for Windows resources such as dialogs, menus, icons and version information.
- The official overview lists support for C99, C11, C17 and C23, with x86, x64 and ARM64 processor targets.
- The author permits free personal and commercial use without download registration.
Watch out for
- The documented host and target platforms are Windows rather than a cross-platform desktop environment.
- The freeware terms allow redistribution but prohibit selling the Pelles C software.
Best for
- C developers building native Windows desktop programs with an integrated compiler and debugger.
- Windows programmers editing dialogs, menus, icons and other application resources alongside C code.
- Projects that need the documented x86, x64 or Windows 11 ARM64 toolchain.
