Stack screenshots into one tall image
A small web app that merges multiple screenshots into a single vertical PNG, normalizing every image to the same width. For anyone assembling a long capture out of several shots.
Key Features
Stacks two or more screenshots top to bottom into one continuous image.
Resizes every input to a uniform 1360px width using Lanczos resampling, keeping aspect ratios intact.
Accepts PNG and JPEG files by drop or file picker, with a removable file list before you merge.
Shows the merged result in the page and saves it as a single PNG.
Why We Built This
Three screenshots, one conversation
Capturing a long page or a chat thread means taking several screenshots, and sending them separately makes the reader stitch the story together themselves. Opening an image editor to do it properly is more work than the task deserves. This drops the files in, scales them all to a consistent 1360px width so nothing looks mismatched, and gives you one PNG back.
Merges any number of screenshots top to bottom into a single PNG you can send in one go.
Every image is scaled to 1360px wide with its aspect ratio preserved, so the seams don't jump.
Drag, drop, merge, download. It runs locally and cleans up its temporary uploads afterward.
