What this does
Open the book flat and take both pages in one photo. The scanner straightens the spread, cleans the paper and splits it into a left and a right page.
Tips
- Press the book flat near the spine with your fingers at the edges.
- Scan in daylight to avoid a shadow from your phone.
- After saving, run OCR PDF to make the text searchable.
How to use it
- Choose what you are scanning and hold the phone over the page: it captures by itself
- Fix corners, retake or reorder pages, pick a look
- Choose the file size and save one clean PDF
Questions people ask

Is Scan to PDF really free?
Yes. Every PDFtoOne tool is free with no login, no daily limit and no watermark. The site is supported by ads.
Is there a file size limit?
We set no limit. Files are processed by your own device, so the only limit is its memory. Computers handle very large files; phones handle most everyday files easily.
