    About Merge Images

    When is it useful? Merge Images joins pictures into one — screenshots one below another for a tutorial, before-and-after photos side by side, or several photos combined into one image to post.

    Good to know: choose Vertical (one below another), Horizontal (side by side) or Grid with 1–10 columns. Pictures wider than the maximum width (1000 px by default) are reduced, and spacing and background colour are adjustable. The combined image is a PNG, with a limit of 32 megapixels in total.

    Example: you want to share four screenshots of a payment process in one message. Choose Vertical with 10 px spacing on a white background, and the steps appear one below another in a single picture that is easy to scroll on a phone.

    Tips for Better Results

    • Use Vertical for long screenshots and chats.
    • Use Horizontal for before-and-after comparisons.
    • Set spacing to 10–20 px with a white background for a neat collage.

    Merge Images: a complete guide

    Why combine pictures

    One combined picture is easier to post and share than several separate ones: a step-by-step tutorial made of screenshots, a before-and-after comparison, a long chat conversation, a set of product views, or a collage of event photos.

    How it works

    Choose Vertical to stack pictures one below another, Horizontal to place them side by side, or Grid with 1–10 columns. Pictures wider than the maximum width (1000 pixels by default) are scaled down; set spacing and background colour for neat gaps. Pictures are combined in the order of the upload list and saved as one PNG, with a total limit of 32 megapixels.

    Choosing a layout

    Vertical suits screenshots and long chats viewed on phones. Horizontal suits two-picture comparisons. A grid suits collages and product overviews. A white background with 10–20 pixels of spacing looks clean on most platforms.

    Common problems and how to fix them

    The result is too long or wide for social media: use a grid, or merge fewer pictures. Pictures have different sizes: smaller pictures are centred in their cells — crop or resize them to similar sizes first. “Exceeds the combined processing limit”: lower the maximum width or use fewer pictures.

    Good habits

    Arrange pictures in the right order before merging, crop away unimportant parts first, and keep the separate originals.
