A before-and-after for a renovation diary
You're documenting the kitchen renovation on Instagram and you want one tidy post that shows the before and after side by side. Two separate photos aren't bad, but they don't land — people swipe past before they realise the second image is the finished kitchen. You want them in one frame, framed identically, the contrast doing the work.
You drop the two photos into the merge tool, pick Horizontal, set spacing to four pixels and the background to white, and the live preview shows you exactly what the post will look like. Drag the "before" to the left, "after" to the right, output as JPG so the file's small enough for a fast upload, and you're done in under a minute.
The post lands. The contrast does the work. Three friends ask which contractor you used.
Building a product spec sheet from device photos
You're an electronics buyer at a small distributor and a supplier just sent you eight close-up photos of a connector — pin layout, side view, top view, three different cable termination shots. You need them in one document for a spec sheet, but the supplier's photos are all different sizes and you don't want to fight Word's image layout for an hour.
You drop the eight photos into the merge tool, pick Grid with 4 columns, set the spacing to six pixels, and the live preview shows a clean 4×2 grid. The spec sheet now has one image to drop in, every shot at native resolution, with a uniform layout that doesn't look amateur. You export as PNG so the small text in the connector pin diagram stays crisp.
Spec sheet done in five minutes instead of forty. The supplier sends a quote the next day.
Sharing a chat screenshot conversation
You're piecing together a conversation thread from your phone — six screenshots from a chat that you want to share as one continuous image so the recipient doesn't have to swipe through them in the right order. You also don't want to upload private screenshots to a server.
You drop the six screenshots into the merge tool, pick Vertical, leave the spacing at the default eight pixels, and the live preview shows the full thread top-to-bottom. The merge runs in your browser — nothing's uploaded — and you save the result as a PNG so the text stays sharp.
You send one image instead of six. The conversation is read top-to-bottom in one go and the recipient gets the context immediately.
