Stitching screenshots is how a scrolling conversation, a long form, or a full web page becomes one shareable image. The tool joins them in the order you set, at their own native resolution — but it joins them exactly as given. It does not detect that the bottom of one capture and the top of the next show the same content, which is the part that decides whether the result reads as continuous or as an obvious set of tiles.
That overlap is unavoidable when you capture by scrolling, because you scroll less than a full screen to keep your place. Every capture after the first therefore repeats a strip of the one before, and often carries a fixed header or a message bar that appears in all of them. Cropping those duplicated strips away before stitching is the single step that separates a clean long screenshot from a stack of near-identical panels — Crop Screenshot Online is the tool for it.
The output format is decided by a setting that does not look like it controls format. A transparent background exports PNG; white or black exports JPEG. Screenshots are text, so PNG is the right answer almost every time — which means choosing the transparent background even though a screenshot has no transparency at all. Selecting white because a screenshot looks white produces a JPEG, and JPEG puts visible artefacts around every letter.
How to stitch screenshots into one long image
- 1
Crop the overlaps first
Before stitching, trim the repeated strip from the top of each capture after the first, along with any fixed header or toolbar. This is what makes the join invisible, and no stitching setting can do it for you.
- 2
Add the captures in order
Drop them in and drag the thumbnails into reading order. The stitched image follows the thumbnails exactly, not the filenames — which matters because screenshot filenames sort by timestamp, not always by sequence.
- 3
Keep the direction vertical and the gap at zero
Vertical is the reading direction for chats, articles and forms. A gap of zero produces a continuous image; add a small gap only when you want the panels to read as separate steps.

Choose transparent, then stitch
This exports PNG, which keeps text sharp. Download the single continuous image.
Pro tip: Capture with a consistent window width and you will never have to fix alignment. Every screenshot in a set needs the same width to stitch into a clean column — resize the browser or app window once, then take all your captures without touching it. If the widths differ, the stitched result centres each panel and fills the difference with background, which reads as a ragged edge down both sides of the image. This is far easier to get right at capture time than to repair afterwards.
Troubleshooting: If the same content appears twice at each join, the overlaps were not cropped before stitching — that is expected, since the tool joins what it is given rather than detecting duplication. If the text looks fuzzy, the export was JPEG because a white or black background was chosen; switch to transparent for PNG. If the edges are ragged, the captures were taken at different window widths. And if the order is wrong, check the thumbnail sequence rather than the filenames.
Trim the captures first with Crop Screenshot Online, which also covers removing sensitive information from the edges. For general merging, Merge JPG Files Into One and Combine Two Images Side by Side cover other arrangements. If the destination is a document rather than one long image, Combine Images into One PDF keeps each capture on its own page, which is often easier to read. The full Merge Images tool handles everything else.
Frequently asked questions
How do I stitch screenshots together into one image?
Crop the overlapping strips from each capture, add them to the tool above, drag them into reading order, keep the direction vertical with no gap, and merge. Choosing the transparent background exports a PNG, which is what keeps the text sharp.
Does the tool remove overlapping parts automatically?
No. It joins the images exactly as supplied, in the order you set. Because scrolling captures always repeat a strip of the previous screen, you need to crop those duplicated sections yourself first — that step is what makes the joins invisible.
Should stitched screenshots be PNG or JPG?
PNG, in nearly every case. Screenshots are flat colour and small text, which is exactly the content JPEG compresses worst — you get visible halos around letters. Selecting the transparent background produces PNG output, so choose it even though a screenshot has no transparency.
Why are there gaps or bars at the sides of my stitched image?
The captures have different widths. Images are centred rather than stretched, so background colour fills the difference. Taking every screenshot at the same window width avoids it entirely, and is much easier than fixing it afterwards.
Are my screenshots uploaded to a server?
No. The stitching happens on a canvas inside your browser and the result is saved directly from there. Nothing is transmitted anywhere — which matters for screenshots, since they routinely contain conversations, account details or internal tools.
