Images to PDF
Many images merged in order into one PDF — sortable, built on-device
Click to pick images, or drag them here
Multiple OK — merged into a PDF in selection order, reorderable later
When to use it
Contracts, IDs and receipts photographed into one sendable file; or a pile of screenshots packed into a page-flippable document — shoot order is adjustable in the list, no re-shooting. This is exactly the content that must never reach someone else's server, so merging stays fully on-device.
Collage or PDF — which one
One long image for group chats: "Image Collage". A flippable, printable, attachable formal document: "Images to PDF". Both take many images with ordering — pick by what the recipient needs.
