Find answers to common questions about our document scanner
Our document scanner uses perspective correction (homography transformation) to straighten your document. Simply drag the corner markers to match your document boundaries, then process to remove shadows, enhance contrast, and sharpen 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 the Rotate, Adjust (brightness/contrast), and Ratio tools. Multiple documents can be cropped together and saved as a single combined PDF.
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 add a document photo, corner detection runs automatically and places markers on the detected document edges. You can use these as-is 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.
After applying the crop, use the toolbar below the canvas: Adjust opens brightness and contrast sliders with live preview, Ratio lets you stretch the width/height proportions of the page, and Rotate turns the document 90° clockwise per tap until the orientation is correct.
If the crop itself needs refining, tap Crop to re-enter crop mode, adjust the corner markers, and apply again. Every change is previewed instantly before you save the PDF.
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 photos appear in a thumbnail strip below the canvas where you can switch between them or drag to reorder; the Reorder tool opens a dedicated panel for arranging pages. This makes it easy to organize multi-page documents before saving them together as a PDF.
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.
