Here is a list of Best Free Focus Stacking Software for Windows. These software come in handy for Photographers, especially while post processing Macro photos or Microscopic photos.
In almost all of the software mentioned, the process to focus stack photos is carried out by loading multiple images, then running the stack tool. These software detect the best focused parts of the images, then combine them to form a single image. All of the mention focus stacking software have GUI except one, which is a command line focus stacking tool.
Some of these software also auto align images if they are out of alignment, which is a great deal if you do not have a tripod to click photos. If you already have a set of photos to stack, then go on, give the listed software a try.
These software carry out various other operations as well, but the focus of the article has been kept on focus stacking of images. While you will get to know about the listed focus stacking freeware, you will also know How to do Focus Stacking with them.
Focus stacking is the process of stacking multiple photos with differently focused areas, captured from a single position. The focus stacking software listed in this article carry out the job of focus stacking pretty easily with satisfying results.
My Favorite Focus Stacking Software:
I like Picolay and TuFuse the most as free focus stacking tools. Picolay lets you easily carry out photo stacking even if you have multiple images to stack, and they are out of alignment. TuFuse is a command line focus stacking tool and manages to provide excellent stacked output. I would recommend TuFuse if you have perfectly aligned images.

Picolay is an amazing focus stacking software for Windows. It is lightweight and carries out the stacking process very swiftly. All you have to do is add a set of differently focused images to this software, then stack them to get an evenly focused output.
The focus stacking process works best for Macro and Microscopic image sets shot from a fixed point. If you do not have a set of pictures ready for stacking, you can refer to the Tips and Tricks for shooting photos for Focus stacking to get perfect pictures for the process. If your pictures are ready to be stacked, you can rely on this software, even if your pictures are out of alignment. The auto alignment feature works pretty well and can be relied upon.
Apart from focus stacking, you can also carry out other types of stacking here. These are: Color based stacking, Average marked images, Auto adjust brightness, Set white balance, Add/Subtract images, Flat-field, Divide by 1st image, etc.
How to do Focus Stacking using Picolay:
- Once you open the software, go to the File tab to add images. Select and add a set of images you’d like to focus stack. The images added are displayed as a list; click on an image to preview it.
- Now go to the Stack operations tab and click on Stack with current parameters. This stacks your images in no time and displays the output on the output preview screen.
- If you did not get satisfactory result because of alignment mismatch, or if the output has noise, you can change the stacking parameters under Stack operations > Set stacking parameters. Here you can set Noise suppression, Smart Filter, Prefer High/Low frame, Align images, Auto enhance, and save depth map.
- Once you get a desired output after focus stacking, you can save the output image from File > Save Result As in gif, png, jpg, png, bmp, tif, ico, emf, or wmf formats.
The set of images I used for testing were out of alignment; however, this focus stacking software took care of it very well.
Apart from stacking, you can also create GIF from a set of images. Load the images and go to the Image List tab to create GIF. You can also create Depth Maps and 3D views from a set of images with this freeware.

TuFuse is an astounding free command line focus stacking software. It combines the best focused parts of multiple shots and produces evenly focused output images. Not only focus, it also combines the fairly exposed parts from multiple images. So the final result is a combination of best focused and exposed portions of the images added. The algorithm implied here works pretty well and gives awesome result every time.
It does not have a GUI and you will have to use certain set of commands to carry out the focus stacking process. If you are really not comfortable with carrying out command line operations, you can download PTAssembler, which is an image stitching software; TuFuse comes along with it and it serves as a GUI for TFuse. For those comfortable with command line operations, here’s how to focus stitch images using TuFuse in command line:
- Open the download folder where TuFuse is downloaded, then open the TuFuse folder.
- Transfer the images to be stacked in this folder.
- Now go to the Address bar of TuFuse folder, select and delete the folder path, then Type CMD there and press Enter.
- This will open the Command Prompt with the TuFuse directory.
- Now enter the following command to focus stack images:
tufuse -o output.tif input1.tif input2.tif input3.tif input4.tif, and press Enter. (In the above command output is the output file name, and input1, input2, and input3 are the input file names.)
- The output will be saved in TuFuse folder itself. The output will always be a TIF file; however, the input can be jpeg, png, bmp, or tif.
There are various image related operations that you can carry out along with focal stacking, such as: Levels manipulation, Contrast/Saturation/Exposure manipulation, etc. To carryout these operations, you need to add special codes along with the above line of code. The list of codes can be found on the homepage of this software.
It is a very easy to use freeware, which produces exceptional photo stacking results. Home Page Download Page
