Scanned PDFs and DjVu files, up to 750 pages a book, or 1,000 on a paid plan. A DjVu file comes back as a PDF. See DjVu to PDF.

Yes. Drop a PDF or DjVu file on the upload page, then sign in, and the book is ready for its crop. If you don’t sign in within an hour, that upload is deleted.

One book is processed at a time. When it is ready, start the next.

It isn’t counted. Try again, or write to us and we’ll look at the file.

There are four. Auto finds the text and trims the scanner edges. Tight closes in on the text. Keep a writing margin keeps half the trimmed edge, with room for notes. No crop leaves the pages as scanned. The crop applies to every page. When left and right pages sit differently, each side gets its own box, found automatically; switch Left and right sides off for one box. Pick where new books start in Settings. More in crop PDF margins.

When two-page scans are found, the crop screen shows the fold line and three choices: Don’t split, Split, or Split and crop with a box for left pages and one for right. Drag the line if it's off. Books that read right to left come out in the wrong order, so choose Don’t split for those. See split two-page scans.

Plain text pages come back pure black on white. Pages with pictures stay in greyscale, so the pictures survive. In Settings you can choose Black and white, Clean greyscale, or Keep original, which only adds searchable text. See grey background.

Slightly tilted pages are straightened, so the lines run level and the crop doesn’t cut into them.

Pages that may need your eye: a blank page, an unusual crop, faint text, or an illustration kept grey. For each one, choose Keep the fix or Use original, then Finish.

The printed numbers do. Every page stays in order with its printed number untouched. When two-page scans are split, the PDF has more pages than the scan, so its page count goes up.

Yes. Every page is read and hidden text goes under it, so search, highlight, copy and dictionary look-up work. See make a scan searchable.

Most are found automatically. Ukrainian and Greek you choose yourself: on the crop screen for one book, or under Text recognition language in Settings for every book.

No. It reads printed text.

No. Your book stays a PDF, with every page, picture and footnote where it was. See scanned PDF or EPUB.

Download the PDF and send it with Amazon’s Send to Kindle. It takes PDFs up to 200 MB on its website and 50 MB by email. See the Kindle guide.

Check the size first: 200 MB on the website, 50 MB by email. Clean black-and-white pages usually compress far better than grey scans. See Send to Kindle not working and PDF too big for Kindle.

A PDF shrinks the whole page, margins included, to fit the screen. Cropping the margins makes the text fill more of it, and the Tight crop closes in furthest. See PDF text too small.

Yes. Send it with Send to Kindle rather than a USB cable: Amazon says handwriting isn’t supported on PDFs loaded over USB-C. See the Kindle Scribe guide.
