How to scan multiple pages into one PDF on Android

One document, one file

Sending page 1.jpg, page 2.jpg and page 3.jpg makes the reader do the work. A single multi-page PDF keeps the pages together and in order.

In Filetray a document is that one PDF. Every page you scan in one session lands in it, and you can come back later to add the page you forgot, put a page in the right place, or drop a blurry one.

4. Add a page you missedInside the document, tap Pages, then Scan more pages, or Add pages from photos. New pages go at the end.
5. Fix the orderIn Pages, tap a page to select it, then tap Earlier or Later to move it. Remove takes it out of the document.

Multiple pages, one PDF: questions

Is there a page limit?

One scanning session takes up to 100 pages. You can add more pages to the same document afterwards with Scan more pages or Add pages from photos.

Does a document with many pages count as more than one?

No. The free library counts documents, not pages: a 12-page contract is one of your 5 free documents.

Can I add photos from my gallery as pages?

Yes. Inside a document, tap Pages, then Add pages from photos, and pick the pictures in order.
