CombineZP review
A free Windows focus-stacking tool with alignment controls and multiple stacking methods.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CombineZP is desktop image-processing software for focus stacking, aimed at photographers working with close-up or macro images. It combines focused areas from multiple photographs into a composite with greater depth of field. The workflow centers on automatic frame alignment, stacking methods, and saved-image export, making it suited to Windows users who want a focused tool rather than a broader image-processing suite. It is distributed as GPL-licensed open-source software and is available at no cost.
The feature set covers both quick and more thorough alignment. Quick alignment is intended for a faster workflow, while thorough alignment adds rotation correction for frames that need more adjustment. CombineZP includes several stacking methods, including Do Stack and Pyramid Maximum Contrast, and can run all available methods. Memory-usage configuration is useful when image sets place heavier demands on the computer, while macro parameter editing gives users additional control over close-up stacking. The documented output is JPEG, with result generation and saved-image export included in the workflow.
CombineZP fits users who value a free Windows utility with direct controls over alignment and stacking choices. Its archival GitHub distribution and reference to a 2012 x86 installer point to a legacy-oriented setup experience rather than a current, broadly integrated imaging ecosystem. It is also not an AI-assisted tool. Choose it when Windows compatibility, no-cost access, and configurable stacking methods matter most. Users seeking a wider platform range, newer workflow expectations, or output beyond JPEG should consider a different focus-stacking option.
