Combine screenshots into one long image
Stacking several screenshots vertically is the clearest way to share a chat history, a long web page, a step-by-step setup guide or a recipe. This tool merges images into a single column in one file.
Editing options
Reorder the images, add spacing between them and pick a background colour. The option to scale everything to the same width turns screenshots from different devices into a tidy column.
