Use OCR to extract quotes, statistics, or information from printed materials for your own writing or presentations. Preserve fragile or old documents by creating high-quality digital scans.
Keep digital copies of receipts for expense reports, tax deductions, or warranty claims. Scan restaurant receipts, gas station receipts, and purchase confirmations immediately to avoid losing them. The OCR feature can extract amounts, dates, and vendor information for easy expense tracking. Perfect for freelancers, small business owners, and anyone who needs to track expenses or submit reimbursement claims.
Convert handwritten notes, forms, letters, and documents into digital format. While OCR works best with printed text, you can still create clear, readable scans of handwritten materials. Useful for preserving family letters, recipes, journals, or meeting notes. Scan completed forms to email instead of faxing or mailing them.
Good lighting is crucial for high-quality scans. Natural daylight provides the best results, but avoid direct sunlight which can create harsh shadows or glare. If scanning indoors, use overhead lighting and position the document to minimize shadows. For documents with glossy surfaces or lamination, tilt the document slightly to reduce glare. Consistent, even lighting across the entire document ensures the best OCR accuracy and image quality.
Place documents on a flat, contrasting background for easier edge detection. A dark document on a light surface (or vice versa) helps the automatic cropping identify boundaries accurately. Remove any items from around the document that might interfere with edge detection. Hold your camera parallel to the document when possible, though our perspective correction can handle angled shots. For multi-page documents, scan one page at a time for best results.
Position your camera far enough from the document to capture it completely with some margin around the edges. Too close and you might miss content; too far and the text becomes harder to read. If your camera has trouble focusing, tap on the document in the preview to set focus manually. Keep the camera steady - use both hands or rest your device on a stable surface. For small documents like business cards or receipts, move closer to fill the frame for maximum detail.
For best OCR results, ensure text is sharp and in focus. Documents with clear, high-contrast text (like black text on white paper) produce the most accurate results. Avoid scanning documents with background patterns, watermarks, or colored paper when possible, as these can reduce OCR accuracy. If the original document is low quality, our image enhancement will improve it, but starting with a clear source gives better results. Straighten crumpled documents before scanning.
For thick documents like books or bound materials, flatten the page as much as possible or scan each page individually. When scanning glossy materials like photographs or laminated documents, adjust the angle to minimize reflections. For very thin or transparent paper, place a white sheet underneath to prevent text from the reverse side showing through. Colored documents scan well, but converting to grayscale can sometimes improve readability for text-heavy pages.
Choose PDF format when you need to preserve document integrity, share via email, or archive important papers. PDFs maintain quality and are universally readable. Select JPG format when you need a quick image that can be easily embedded in documents, presentations, or websites. JPG files are typically smaller and easier to share via messaging apps. For documents you plan to edit later, PDF format works better with editing software. If you need to extract text, use the OCR feature before downloading.
Unlike mobile scanning apps that require installation and often limit free scans, our web-based scanner works instantly in any browser with no downloads. You get unlimited scans without signing up for accounts or subscriptions. Mobile apps often compress or watermark free scans, but we provide full-quality PDFs and images at no cost. Our tool works on any device - phones, tablets, laptops, or desktops - giving you flexibility that single-platform apps cannot match.
Many scanning apps collect user data, upload documents to their servers, or require cloud storage accounts. We process most operations directly in your browser, ensuring your documents remain private. No tracking, no data collection, no cloud requirements. Your scans are yours alone.
Traditional flatbed scanners and all-in-one printers are expensive, require desk space, and need driver installation and maintenance. Our online scanner turns any device with a camera into a powerful scanning tool. No hardware costs, no setup, no maintenance. Scan documents from anywhere - at the office, home, coffee shop, or while traveling.
Physical scanners limit you to specific locations and can be slow, especially for single-page documents. With our tool, you can scan a receipt immediately after a purchase, digitize a contract during a meeting, or capture notes right after a lecture. The convenience of always having a scanner in your pocket through your smartphone is invaluable.
Professional document scanning services charge per page or require monthly subscriptions. Our free scanner delivers comparable quality with automatic perspective correction, edge detection, and image enhancement. You get features like OCR text extraction that would normally require expensive software. Perfect for individuals, students, and small businesses who need professional results without ongoing costs. Scan hundreds of pages without worrying about fees or limitations.
When you send documents to copy shops or use office scanners, others may access your sensitive information. Our scanner processes documents privately - most operations happen locally in your browser without uploading to external servers. This is crucial for confidential business documents, personal financial information, medical records, or legal papers. You control your data completely, with no third-party access or storage of your scanned documents.
If the camera doesn't open, check that you've granted camera permissions in your browser settings. Most browsers will prompt you the first time - click "Allow" when asked. On mobile devices, check your device's system settings to ensure the browser has camera access. If using HTTPS is required for camera access, make sure you're on a secure connection. Try refreshing the page or using a different browser if problems persist.
If automatic edge detection misses document boundaries, ensure there's good contrast between the document and background. Place dark documents on light surfaces or vice versa. Remove any other papers or objects from the background. If detection still fails, you can manually adjust the crop boundaries by dragging the corner handles to encompass your document precisely.
Blurry results usually come from camera movement or poor focus. Hold your device steady with both hands or rest it on a surface. Tap the document on your screen to focus the camera on it. Ensure adequate lighting - dim conditions force the camera to use slower shutter speeds that blur easily. Clean your camera lens if images consistently appear hazy. Move the camera slightly farther from very small text to help with focus.
OCR accuracy depends on image quality and text clarity. Rescan with better lighting and focus if results are poor. OCR works best with clear, printed text - handwriting recognition is limited. Documents with unusual fonts, very small text, or heavy background patterns may have reduced accuracy. Try enhancing the image contrast before scanning or use a higher resolution camera if available. For best results, scan one page at a time rather than trying to OCR multiple pages in one image.
Mobile browsers handle downloads differently than desktop browsers. On iOS, PDFs may open in a new tab instead of downloading - tap the share icon and select "Save to Files" to save them. For images on iOS, tap and hold the image, then select "Save Image." On Android, check your Downloads folder or notification area for the downloaded file. If sharing is available on your device, use the Share button to send files directly to other apps or contacts.
Processing time depends on image size and internet connection speed. Very large images (like those from high-end phone cameras) may take longer. For faster processing, you can resize images before uploading, though this may reduce quality. Ensure you have a stable internet connection. If processing consistently fails or times out, try scanning at a lower camera resolution or compress the image size before uploading.

Absolutely. Most processing happens locally in your browser. For features requiring server processing, files are automatically deleted immediately after conversion. We never store, access, or share your documents.
You can save scans as high-quality PDF documents or JPG images. PDF is recommended for documents you need to share, email, or archive. JPG works well for quick sharing or embedding in other documents.
OCR is optimized for printed text and works best with clear, typed documents. While it may recognize some neat handwriting, accuracy is significantly lower than with printed text. For handwritten documents, we recommend saving as images rather than relying on text extraction.
Currently, each scan creates a single-page PDF. To create multi-page PDFs, scan each page individually and then use our Merge PDF tool to combine them into one document. This gives you flexibility to reorder pages or remove any that didn't scan well.
Our OCR engine supports multiple languages including English and other major languages. The automatic language detection works for most documents. For best results with non-English documents, ensure clear, high-contrast text in the scan.
Yes! The scanner is fully optimized for smartphones and tablets. It works on iOS (iPhone/iPad), Android, and all modern mobile devices. Your phone's camera becomes a powerful portable scanner.
Our scanner uses computer vision algorithms to identify document boundaries automatically. It detects edges based on contrast, color differences, and shape patterns. While highly accurate, you can always manually adjust the detected area by dragging the corner handles.
Scan quality depends on your camera resolution. We support cameras up to 1920x1080 or higher, automatically optimizing for clarity while keeping file sizes reasonable. The resulting PDFs and images maintain excellent readability for both screen viewing and printing.
The scanner creates standard PDF files that can be edited with PDF editing software. Use our Edit PDF tool for basic modifications, or convert to Word format using our PDF to Word converter for extensive editing. The OCR feature lets you extract text for copying and editing separately.
No limits! Scan as many documents as you need. Individual scans are optimized for quality while maintaining reasonable file sizes, typically 200KB to 2MB depending on document complexity and camera resolution.
