stack a bunch of images into one, even if the widths don't match
trying to combine a multi-part infographic or recipe card series and every piece is a slightly different width, so stacking them just looks... off? this tool fixes that automatically before merging.
what this does
ImageStream's Merge Vertically tool stacks multiple images top to bottom into one long vertical image. good for infographics, joining screenshots, recipe cards, chat capture compilations.
free, no signup
everything processes in your browser, nothing uploaded
auto width normalization — different widths get resized to match, so nothing looks lopsided
merge up to 20 images at once
adjustable gap + background color
export as PNG, JPEG, or WebP
how to use it
upload your images in order (up to 20)
check the order, tweak gap and background color
preview, download
mixing a phone photo with a screenshot? no problem — widths get normalized automatically so nothing's misaligned.
when this is actually useful
putting a multi-part infographic back together. if it got split across several files with slightly different widths, this stitches it into one clean, aligned image.
combining recipe or tutorial cards. step-by-step cards with inconsistent widths get stacked into one polished guide with everything lined up.
organizing photos from mixed sources. phone pics, scanned docs, screenshots — all different sizes, all normalized to one width before stacking.
quick FAQ
what if my images are different widths? they all get resized to match before merging, so the result stays aligned top to bottom.
how many can I merge? up to 20 at once.
what formats? PNG, JPEG, or WebP, your call.
want to keep the original widths instead? if you don't want any resizing — just aligning images as-is (left/center/right) — the Stack tool is the better pick. built for stuff like consecutive screenshots that are already close in width.
want horizontal instead? there's a horizontal merge tool too — same deal, different direction.
more free browser-based image tools over at ImageStream — collage maker, image comparison, all no signup.
want to skip the resizing and just align images as-is? the Stack tool does that.
