Features

📷

Camera or Upload

Snap a photo directly with your device camera (back camera preferred on mobile), upload a file, drag & drop, or paste an image with Ctrl+V.

🔲

Four-Corner Perspective Correction

Drag the four corner handles to fit your document's edges, then confirm to straighten a skewed photo into a clean rectangular scan.

🎛️

Rotate & Fine-Tune

Rotate in 90° steps, fine-tune the angle from -45° to 45°, and trim margins to remove unwanted background.

Scanner-Style Filters

Choose original color, grayscale, high-contrast black & white (like a real scanner), or a color-boosted enhancement — applied instantly.

📑

Multi-Page Management

Keep scanning to build a page list with thumbnails. Reorder, delete, or re-edit any page before exporting.

🔒

Private & Offline

All processing happens locally in your browser using Canvas — no photo is ever uploaded to a server. Pages persist locally so you won't lose progress on refresh.

Frequently Asked Questions

Is this document scanner free to use?
Yes, it's completely free with no sign-up, watermark, or page limit.
Are my photos uploaded to a server?
No. All perspective correction, filtering, and PDF generation happen entirely in your browser using Canvas. Photos never leave your device.
What if my browser doesn't support the camera?
If camera access isn't available or permission is denied, you can still upload a photo file, drag & drop it, or paste it with Ctrl+V.
Can I scan multiple pages into one PDF?
Yes. Keep capturing or uploading pages to build a page list, reorder them as needed, then export all pages as a single merged PDF.
Will I lose my scanned pages if I refresh the page?
No, scanned pages are saved locally in your browser's IndexedDB and will still be there when you come back.
