QBMFX Auto crop and deskew
Trim obvious outer background from a paper photograph and correct small page tilt before creating a printable copy. Automatic estimates work best when a light page is surrounded by a contrasting background. Check the proposed result and use the manual angle when the detected paper edges or text direction do not match your document.
Choose your files and review the settings.
Keep originals and inspect the result before printing. File changes clear previous downloads. Heavy image and OCR work can take longer on a phone.
Using Auto crop and deskew
- Choose a scan with the full paper visible.
- Use automatic cropping and deskew, or enter a manual rotation angle.
- Review the page edges and save the corrected image.
Behind the result
The image is sampled to estimate paper boundaries and small rotation. The selected region is transformed into a new image; this changes pixels rather than correcting the physical paper.
Free tools for everyday work
Book centers, photocopy shops, freelancers and developers can use this workspace without a paid plan or account. Files are processed locally. Prepare website resources from offline setup before disconnecting; Urdu/OCR also needs the separate pack above.
The Windows app currently includes the original four tools. These new Book Center tools are available on the website; app and extension updates will be separate releases.
Answers and practical details
Automatic detection limits
Low contrast between the paper and desk, decorative borders and edge-to-edge graphics can confuse paper detection. A clear, flat photograph produces a better estimate.
Price and account requirements
This website tool is 100% free. No login, subscription or paid conversion tier is required. Your device supplies the processing memory.
Files and privacy
Input documents and generated results are handled locally. They are not sent to a QBMFX conversion API or stored in a customer database. Website hosting and advertising can still make separate network requests.
Offline preparation
Prepare the website resources from Help while connected, then test the required tool offline. OCR and Urdu text tools also need their optional language or font resources prepared first. Browser storage can be removed by the browser or by you.
Windows app and Edge extension
The existing installed app and extension contain the original four PDF tools. These new Book Center tools belong to the website release; they will need a separate installed-package update.
