About Smart Document Scanner
Scan document photos or capture pages with your camera, adjust page corners and straighten perspective on your device. Choose Color, Gray or Clean, arrange pages and export one PDF in A4, US Letter or the scan proportions. Clean creates a black and white scan and can remove faint details, so check the preview. Automatic boundary detection can miss pages against a similar background. Extract printed text separately into an editable text box and TXT download. PDF pages remain images, not searchable text. Recognition accuracy depends on lighting, print quality and language.
Smart Document Scanner runs locally without uploading your selected file or requiring an account. Although file selection allows up to 1 GB, available device memory can limit this particular task.

Common questions
Can I scan documents with my phone camera?
Yes. Scan with camera opens the available camera after permission. Capture one page at a time and add more pages. Camera access requires a secure connection and browser permission. You can choose existing document photos instead.
Does the scanner automatically crop and straighten a page?
It looks for a clear four sided page boundary and corrects perspective. Check the preview and use Adjust corners if detection misses an edge. When no boundary is found, the full photo is retained rather than inventing a crop.
What do Color, Gray and Clean change?
Color preserves visible colors. Gray removes color. Clean applies local black and white enhancement for printed pages. Faint writing, stamps and photos can lose detail in Clean, so compare the preview and use Color when needed.
Can I combine several camera scans into one PDF?
Yes. Add pages, select a thumbnail and move it earlier or later before creating the PDF. Remove unwanted pages with the trash control. The saved document follows the displayed page order.
Which PDF sizes can I select for scans?
Choose A4, US Letter or Fit scan. Paper presets fit each scan without stretching and follow its portrait or landscape orientation. Fit scan preserves the page proportions. Working images are limited to a longest side of 2400 pixels for device memory.
Can I copy words from the scanned PDF?
The PDF contains page images, not a searchable text layer. Extract text recognizes the prepared pages separately into an editable box, with Copy text and a TXT download. Use OCR PDF if you need a searchable PDF afterward.
Which recognition languages are available?
Choose English, Spanish, Portuguese, French, German, Arabic, Korean or Simplified Chinese. Match the printed document language and review names, dates and numbers. Handwriting and complex tables may not be recognized accurately.
Are camera scans uploaded or stored?
No. Detection, perspective correction, PDF creation and text recognition happen on your device. Processing libraries and recognition language data download when needed, but your document photos are not sent with them. No document is saved in browser storage.
Can I change the PDF after scanning?
Use Edit PDF for annotations, Merge PDF to combine it with other documents, or Compress PDF to reduce supported photo data. Keep a copy of the original photos until you have checked the saved scans.
