Why does my horizontal strip have white bands above/below shorter images?

Because they're shorter than the tallest one. Switch the scale to 'match height' to resize everything to the shortest, or use 'middle' / 'bottom' align to move the bands.

PNG is lossless and keeps transparency — pick it for screenshots or anything with text. JPEG compresses photos far smaller; the quality slider lets you trade size against artifacts.

Image Stitcher (Horizontal / Vertical)

Image

Merges a row or column of images into a single PNG or JPEG. Different from a sprite sheet — this is for making screenshots side-by-side, photo strips, before/after comparisons, or a long scrolling app capture. Pick how to align mismatched-size images (top/middle/bottom for horizontal, left/center/right for vertical), optionally scale them all to the same height/width, and choose a background or keep it transparent. Everything happens in canvas in the browser, no upload.
