// how page size and ordering work
Each image becomes one page, in the order the thumbnails appear. Drag any thumbnail to move it; the numbered badge updates so you always know what page it'll land on. Click the × to drop an image before exporting.
- Fit to image: every page matches its image's pixel dimensions exactly, no borders. Best for scans, screenshots, and on-screen viewing.
- A4 / US Letter: each image is scaled to fit inside the sheet with a small margin and centered. Orientation is chosen automatically, so wide images get a landscape page. Best when the PDF will be printed.
Privacy: images are read into memory and assembled into a PDF entirely in your browser using pdf-lib. Nothing is uploaded, and closing the tab clears everything.
