Long books
This tool reads up to 50 pages at a time, because the reading happens in your browser’s memory. For more, do the PDF in parts, or send the whole book to FixMyScan.
Why there is a limit
Every page is drawn as a large image and read in the open tab. Fifty pages fits comfortably on most computers. Past that, browsers start to slow down or close the tab to free memory, and you lose the work.
Doing it in parts
Split the PDF into pieces of 50 pages or fewer with any PDF splitter.
Run each piece through OCR PDF.
Join the searchable pieces back together with a PDF merger.
It works, but for a 400-page book that is 8 runs and a merge.
A whole book in one go
FixMyScan takes the whole scanned book, up to 1,000 pages, cleans every page, crops the edges and adds the text layer on its servers.
