How it works

See What Changed in Three Steps

1
Add two screenshots
Paste, drop or choose them — or compare a result from another Shotexa tool against its original, without uploading anything again.
2
Pick how to look
Side by side, a before/after slider you can drag, an overlay with adjustable opacity, or a pixel difference that highlights what changed.
3
Export the comparison
Save what you see as a single image. Both originals stay exactly as they were.

Questions

Can I compare screenshots of different sizes?: Yes. Both are fitted into one shared frame and neither is ever stretched. You choose whether each is shown whole, fills the frame, or keeps its natural pixels — and how they are aligned.
What does Difference actually show?: Where the pixels differ, and how much. It is a plain pixel comparison: Shotexa does not tell you that a button moved or that text changed, because it does not interpret the picture.
Does the exported slider still move?: No. The export is a still image saved at the divider position you left it at. Move the divider and export again for a different split.
Are my screenshots uploaded?: No. The comparison is drawn in your browser. Neither screenshot is sent to a server.
