Focus Stacking Online vs PICOLAY

Focus Stacking Online combines photographs of one scene taken at different focus distances, blending the sharp portions into a single image. The maker describes it as free to use in a browser, without installing software. The workflow is to add pictures, choose an alignment method and a reference picture, stack the images, then download the result. Standard and Beta alignment methods are listed; the maker says Beta can perform better in some cases. A reference picture can be selected according to how much of the subject is in focus. The service is described as working on home laptops and smartphones. Focus stacking is presented as useful for producing sharper images, particularly in macro photography, where depth of field can be shallow. The maker recommends keeping the camera fixed because camera shake and scene variation can make stacking harder. A stack may contain two images or more than 100. The homepage also describes a recent stacks gallery and a feature for sharing to social media. FAQ and Contact us links are provided.

PICOLAY is a free Windows program for improving images made from picture series. Its focus-stacking process combines sharp areas from photographs taken at different focus levels in a z-stack. From stacks, it can generate depth maps, 3D projections, stereo images, hologram views, and 3D animations. Editing tools cover resizing, color and sharpness adjustments, filtering, rotation, flipping, painting, cloning, text, and scale bars. It can align displaced stack images by their x and y positions and harmonize their brightness. PICOLAY runs without installation and can be copied to a folder or USB stick. Downloads include 64-bit versions and a 32-bit ZIP version. The download page labels the current release Version 2026-09-29 and lists AI-supported builds. The maker says some antivirus programs may flag the download because distribution is limited and its reputation score is weak. PICOLAY is offered as-is without warranty and may be used freely for non-commercial purposes. Manuals are available in five languages, with tutorials and FAQs linked.
