Find answers to common questions about our document scanner
Our document scanner uses advanced computer vision algorithms to detect the edges of your document in a photo when you click the Detect Edges button. It then applies perspective correction (homography transformation) to straighten the document, removes shadows, enhances contrast, and sharpens text for a professional scanned appearance.
The tool processes everything locally in your browser using JavaScript and HTML5 Canvas with high-quality rendering optimizations. You can fine-tune results with adjustable brightness, contrast, aspect ratio, and rotation controls. Multiple documents can be processed together and exported as individual files, combined PDF, or ZIP archive.
Yes! Our document scanner is completely free to use with no limitations. You can scan as many documents as you want without any watermarks, subscriptions, or hidden fees. All features are available at no cost.
Absolutely! All document processing happens entirely in your browser - your images are never uploaded to our servers. Your documents remain completely private and secure on your device. We cannot see or access any of the documents you scan.
You can scan any type of paper document including receipts, invoices, contracts, business cards, notes, letters, certificates, whiteboards, handwritten notes, forms, tickets, and more. The tool works best with rectangular documents that have clear edges.
We support all popular image formats including JPEG, PNG, WebP, HEIC, and more. You can upload photos taken with your smartphone, digital camera, or from any image file on your computer.
Yes! When you upload a document, corner markers automatically appear covering 80% of the image area. You can use these as-is, click "Detect Edges" for AI-powered detection, or manually adjust the four corner markers by dragging them to the exact corners of your document. This is useful for documents with unclear edges or complex backgrounds.
The tool includes a magnifier feature that appears during corner adjustment for pixel-perfect placement. On touch devices, the markers are enlarged for easier manipulation, making it simple to adjust corners precisely even on smartphones.
Choose Color mode for documents with important colors like receipts, colorful forms, or photos. Select B&W (black and white) for text-heavy documents like contracts or handwritten notes - this reduces file size and improves text clarity. Use High Contrast mode for faded, low-quality, or difficult-to-read documents that need maximum enhancement.
After processing, you can further adjust the result using real-time preview controls for brightness, contrast, width, and height. Rotation controls are also available if the document orientation needs correction.
Yes! Our document scanner is fully responsive and works perfectly on smartphones, tablets, and desktop computers. You can take a photo with your phone's camera and scan it immediately in your mobile browser.
For best results: 1) Take photos in good lighting conditions. 2) Position the camera directly above the document when possible. 3) Ensure the entire document is visible in the photo with some background around the edges. 4) Keep the document as flat as possible. 5) Use a contrasting background (e.g., white paper on dark table).
Yes! Our tool supports batch processing. You can upload multiple document photos at once by selecting multiple files or dropping them all together. Each document will be shown in a thumbnail gallery, and you can process them individually or work through them sequentially.
All processed documents are collected in a separate list where you can reorder them by dragging and dropping. This makes it easy to organize multi-page documents before exporting them together as a PDF or ZIP file.
When exporting multiple documents as PDF, you have extensive customization options:
These settings ensure your PDF documents meet your specific needs, whether for printing, archiving, or sharing digitally.
