ScannerOnline resultWhat is an online book scanner?
An online book scanner is a web tool that turns photos of an open book into separate, flat, readable pages, with no book scanner hardware and no need to cut the binding.
ScannerOnline is a free online book scanner that works from ordinary phone photos. Each photo of a spread becomes two pages: it finds the spine, corrects the curve of the paper and sharpens the text, then builds a single PDF.
Built for open books
Flattens curved pages
Measures how the lines of text bend near the spine and straightens them. If a correction would not improve the page, it is left alone.
Trims the page stack
Removes the band of page edges that shows up along the side of thick books.
Keeps your page order
Orders pages by when each photo was taken, so the PDF starts with your first shot.
Sharp text for reading
Black and white output keeps thin strokes crisp, while grayscale and color suit illustrations.
Tips for a better book scan
- Use even light and avoid casting the shadow of your phone on the page.
- Hold the phone parallel to the book, directly above the spine.
- Keep the whole spread in the frame, with a little background around it.
- Press the pages flat and keep your fingers away from the text.

Frequently asked questions
How can I scan a book without a book scanner?
Photograph each open spread with your phone, add the photos to ScannerOnline and download the PDF. ScannerOnline splits the pages and flattens the curve for you.
Is this book scanner free?
Yes. ScannerOnline is free to use, and you do not need to sign up or install anything.
Does it separate the two pages of an open book?
Yes. ScannerOnline detects a two-page spread automatically and creates a left and a right page. If the split is off, you can crop each page by hand.
Does it remove the curve near the spine?
Yes, in most photos of printed text. ScannerOnline corrects the curve and checks the result. When a correction would not make the lines straighter, it keeps the page as photographed.
How many pages can I scan at once?
You can add up to 50 photos every 15 minutes, and each photo of a spread produces two pages. It takes JPG, PNG, WebP and HEIC photos up to 50 MB each.
Will the pages stay in order?
Yes. Pages follow the time each photo was taken. On a computer you can also drag pages to reorder them.
Can I scan any book?
Only scan books you have the right to copy, such as your own work, books in the public domain, or copies allowed by the law where you live.
