Focus Stacking Online review
A focused, free browser workflow for occasional multi-image stacking.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Focus Stacking Online is a browser-based application for photographers who combine images focused at different depths into one sharper image. It is aimed at occasional users who want to process a focus stack without installing desktop software. The workflow starts with uploading multiple source pictures, then choosing an image-alignment method and selecting a reference image. After processing, the resulting focus-stacked image can be downloaded.
Its main strength is a focused workflow with useful controls before processing. Automatic alignment is supported, while the alignment-method selector gives users a way to choose how source images are matched. Selecting a reference image adds another control over the stack setup. The Free plan provides online focus stacking, and the service is available through the web, making it a practical fit for photographers who prefer browser-based tools and do not need a broader editing environment.
The trade-off is scope. Focus Stacking Online concentrates on uploading source images, aligning them, generating the stack, and downloading the result; it is not positioned as a wider photo-editing workspace. Its web-only platform also makes it less suitable for photographers who require a desktop application or a more extensive local workflow. Pick it when the priority is a straightforward, free way to combine multiple focus depths online. Choose another tool when you need capabilities beyond the published stacking workflow, such as a desktop-centered editing environment or more expansive image-processing controls.
