What it is

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.

Focus Stacking Online in depth

Read the full write-up

Focus Stacking Online combines photos focused at different distances into a sharper image, with a particular fit for macro photographers working on a laptop or smartphone. Its appeal is a free workflow that runs in a browser; the main condition is a steady, consistent capture sequence.

Overview

The service blends the sharp areas of multiple photographs to create one image, addressing the shallow depth of field common in macro work. To make a stack, add the photos, choose an alignment method and reference picture, then download the result. No installation is needed, which suits photographers who want to work from a browser rather than set up desktop software.

The maker says a stack can range from two images to more than 100. That accommodates short sequences as well as extensive ones, but capture discipline matters: camera shake and changes in the scene can make the images harder to combine. The maker recommends keeping the camera fixed and choosing a reference picture according to how much of the subject is in focus.

Key features

Two alignment methods: Standard and Beta give users a choice when aligning a sequence. Beta can outperform Standard in some cases, so it is worth trying when the standard method is not a good fit; it is not presented as a consistent improvement.

Reference picture selection: Users choose a frame to guide the stack. The maker’s advice to consider how much of the object is in focus gives the choice a practical basis.

Gallery and sharing: The homepage describes a gallery of recent stacks and a feature for sharing to social media. These are useful for displaying work, though the core purpose remains image stacking.

Help channels: FAQ and Contact us links provide routes to guidance and support.

Pricing

The Free plan costs nothing and is described as free online focus stacking. It is the natural fit for hobbyists and photographers who want to try browser-based stacking without a software purchase. The maker describes the service as completely free to use online. No paid tier is part of this plan information.

Platforms

The supported platform is web, and the maker says the service works in a browser on home laptops and smartphones. That makes it useful across Android, iOS, Linux, macOS and Windows devices when they can run a browser, without requiring an installation.

Who it's for

Focus Stacking Online is best suited to macro photographers and other close-up shooters who already capture a sequence at different focus distances and want a straightforward way to combine it online. It is also a sensible choice for occasional use, where a free browser workflow is more appealing than installing a dedicated program. Photographers whose scenes or camera positions change between frames should look for a workflow better suited to inconsistent inputs.

Pros and cons

Pros: Free online access avoids a software cost; browser use avoids installation; Standard and Beta alignment offer a choice; the reference image gives users a way to guide the stack.

Cons: The maker recommends a fixed camera because shake and scene variation complicate stacking; Beta only may outperform Standard in some cases, so alignment results can depend on the sequence.

Alternatives

Focus Stacking Software is a useful starting point for comparing more options. Consider CKAN if you want a free, MIT-licensed option for Linux, macOS or Windows. ImageFocus Alpha is another free option across desktop and mobile platforms, designed for compatible Euromex camera models. Choose PlaneFuse if you want free personal and commercial use, no tiers, and web, self-hosted or API platforms.

focus-stack is a free desktop alternative for Linux, macOS and Windows. OpenFocus may suit users looking for an MIT-licensed GUI on Windows or macOS, with a CLI also available on Linux. ChimpStackr is a free, GPL-3.0 option for Linux, macOS and Windows, while ForgePix is a free MIT-licensed alternative for those platforms. Helicon Focus is a paid alternative for macOS and Windows with a free trial.

Verdict

Choose Focus Stacking Online if you want free focus stacking in a browser, especially for macro sequences you can capture with the camera held steady. The choice of alignment method and reference frame adds useful control to a simple workflow. Look elsewhere if your priority is a desktop application or your shooting conditions make consistent frames difficult.

Verdict

Focus Stacking Online offers a browser-based workflow with two listed alignment methods. Keeping the camera fixed is important according to the maker’s guidance.
