Focus Stacking Online

Focus Stacking Online combines pictures of the same scene taken at different focus distances, blending their sharp regions into a single image. It runs in a web browser, and the maker says users do not need to install software. The workflow is to add pictures, choose an alignment method and a reference image, stack the set, then download the result. Standard and Beta alignment methods are listed; Beta can outperform Standard in some cases. The maker recommends choosing a reference picture based on how much of the subject is in focus. The service is described as free and usable on home laptops and smartphones. Focus stacking is presented as particularly useful for macro photography, where depth of field can be shallow. The maker advises keeping the camera fixed because camera shake or scene variation can make image stacking harder. A stack can range from two images to more than 100. The homepage also describes a recent stacks gallery and a feature for sharing to social media, and provides FAQ and Contact us links.

Focus Stacking Online provides a browser workflow to align and combine differently focused photos, then download the result. The maker’s fixed-camera advice is worth considering before assembling a stack.

It suits photographers looking to combine images of a subject focused at different distances, particularly for macro work. Browser access may suit people using a laptop or smartphone who do not want to install software.

Focus Stacking Online is a free browser service for photographers combining close-up frames with different focus points. It is a sensible fit for occasional macro work or anyone who wants to stack images on a laptop or phone without installing an app.

Its straightforward workflow and automatic alignment keep the process accessible, while the need for a steady camera and consistent scene makes capture discipline part of the job.

Overview

Focus stacking blends the sharp areas of photos taken at different distances into one image, helping address the shallow depth of field common in macro photography. Add the pictures, choose an alignment method and a reference frame, create the stack, then download the result. The browser-based approach suits users who prefer not to install software and can work from a home laptop or smartphone.

The maker recommends keeping the camera fixed: shake or changes in the scene can make frames harder to combine. A stack can range from two images to more than 100, so the workflow can accommodate both small sequences and larger sets. Users also choose a reference image based on how much of the object is in focus, giving them a direct say in how the stack is guided.

Key features

• Standard and Beta alignment: The two options give users another method to try when a stack does not align well. Beta may outperform Standard in some cases, though it is not a guaranteed improvement.
• Reference-image choice: Selecting a frame with an appropriate amount of the subject in focus gives users control over the reference for the stack.
• Recent-stacks gallery: The homepage describes a gallery of recent work and a feature for sharing to social media, useful for displaying finished stacks alongside the core workflow.
• Browser access: No installation is required, making the service practical across home laptops and smartphones.

Pricing

The Free plan costs nothing and provides free online focus stacking. The maker describes the service as completely free to use online. It includes automatic alignment, and no paid tier or seat-based plan is part of this offer. That makes it an easy option to try for occasional work; photographers needing a different workflow or software they can install may prefer a desktop alternative.

Platforms

The service runs in a web browser, with the maker describing support for home laptops and smartphones. It is categorized for Android, iOS, Linux, macOS, web, and Windows. Browser access avoids an installation, but users need a browser to use the service.

Who it's for

Focus Stacking Online suits photographers who want to combine a sequence of differently focused pictures without installing software, especially macro photographers trying to bring more of a close subject into sharp focus. It also fits people who prefer a browser workflow on a laptop or phone. Photographers who cannot keep the camera and scene consistent may find the capture requirements a real constraint, since movement can complicate the stack.

Pros and cons

• Pro: The free online service avoids a software purchase and installation, which suits occasional stacking and users moving between devices.
• Pro: Standard and Beta alignment, plus a selectable reference image, offer some control over how a sequence is combined.
• Pro: The workflow can handle stacks described as ranging from two images to more than 100.
• Con: Camera shake and scene variation make stacking harder, so reliable results depend in part on careful capture.
• Con: The browser workflow may not suit users who specifically want installable software.
