How to Stitch Screenshots Into One Long Image

A conversation that spans four screenshots, a receipt too long for one screen, an article you want to save whole. Scrolling content produces fragments, and sharing four separate images in the right order rarely survives a group chat. Stitching them into one continuous image fixes that. Here's how to do it so the result stays sharp and readable.

Open the Image Combiner

Step 1: Take screenshots with overlap in mind

Before capturing, scroll so each screenshot starts where the previous one ended, a clean handoff with no repeated lines. A small overlap is fine (you can crop it later), but repeated paragraphs in the middle of the final image look sloppy. On most phones, scrolling half a message or one paragraph past the previous screenshot's end works well.

Step 2: Add them in order

Click Add Images and select all the screenshots at once. If your file manager selected them out of order, don't re-upload. Drag any screenshot onto another in the preview to reorder. The numbers on each image show the current sequence.

Step 3: Stack them seamlessly

  1. Choose the Vertical layout. Screenshots joined top to bottom read like one long scroll.
  2. Keep Spacing at 0 so the pieces join with no visible seam.
  3. Leave Size on Reduce. Screenshots from the same phone are already identical widths, so nothing gets scaled at all; if you mix sources (phone + desktop), Reduce scales them to a common width without blurring the smaller one.

Step 4: Export as PNG

This is the one place format choice really matters. Screenshots are full of text and sharp edges, and JPG compression smears exactly those. Pick PNG in the format dropdown next to Download. The file is bigger, but every letter stays crisp. Use JPG only if the file size matters more than text sharpness (e.g. an email attachment limit).

Very long stitches: the combined image is capped at 8000 pixels on its longest side, which is roughly 8 to 10 phone screenshots at full resolution. If you're joining more than that, the output scales down automatically to fit, still readable but slightly smaller. For extreme cases, stitch in two halves.

Sensitive content stays private

Chat screenshots are often exactly the thing you don't want uploaded to a random website. This tool does the stitching locally in your browser: the images never leave your device, nothing is stored, and there is no account.

Horizontal stitching

The same technique works sideways for wide content: two halves of a spreadsheet, a panorama captured in sections, side-by-side app comparisons. Pick the Horizontal layout instead, keep spacing at 0, and use Reduce so mixed heights level out.
