About this tool
Image Joiner composes several images into a single file in your browser: a long vertical capture from several screenshots, a before/after side by side, a strip of product photos. Order them with the arrows, choose direction, alignment, spacing and background, and download the result as PNG, JPEG or WebP.

Frequently asked questions
How are images of different sizes handled?
They keep their size; the alignment option decides whether smaller ones sit at the start, centre or end of the row or column.
Which format should I pick?
PNG keeps transparency and is lossless; JPEG is smallest for photos; WebP is small and keeps transparency.
