Looking for software to stitch or merge images together?

I’m looking for software to stitch or merge images together. The images are just screenshots, so there’s no lens distortion or anything like that to worry about. They’re also in a single direction (screenshot, scroll, screenshot, etc.). I tried “Image Composite Editor,” but it wasn’t great for this, and “Hugin” was really slow and didn’t finish the job (I waited 30 minutes and then gave up). I’ve also tried mobile apps, but they were slow and often messed up the results.

I would re-screenshot it with ShareX

Unfortunately, it’s not possible. It’s in an app, and I tried some apps, but they either didn’t work, couldn’t handle long screenshots, or couldn’t finish the job properly. There are too many images for the phone to handle, and it’s not happy about it.

Wait, are you looking for something for your phone or for Windows? Because ShareX can take screenshots of anything you see on your computer.

And if you need to capture a long screenshot on a mobile device, both Android and Apple can handle that natively.

Windows, I’m looking for something that can stitch the images, I already have them, just couldn’t stitch them

You’d have to stitch them together by hand in GIMP or PhotoPea, both of which are free.

But honestly, it might be easier to just re-screenshot them. Your mobile device can handle that natively.

I’m wondering if there’s enough overlap between your screenshots for stitching.

I’ve used ICE for years, and it works perfectly for about 95% of my panoramas, even when hand-held. It handles scans with no perspective distortion really well.

I’ve also used Hugin a lot and never found it to be slow, even with heavy files. It’s just cumbersome to fine-tune the results by setting corresponding points with the mouse

I’ve got about 1/3 overlap between the images above and below. When I tried ICE, the result was a bit off, it ended up looking skewed to the right, like the Leaning Tower of Pisa. I didn’t try manually setting the key points in Hugin because that would have taken forever and might not be accurate.

I’m going to give something else a shot, and if that doesn’t work, I guess I’ll just write some code to handle it.

1/3 is quite enough.
