Scan to PDF · Free, No Watermark
Upload document photos → auto edge detection → perspective correction → export to PDF, Word, or ZIP. Better than CamScanner.

Upload document photos
HEIC, JPG, PNG, WebP, BMP, TIFF · one image per page
Smart Edge Detection
CLAHE adaptive contrast + multi-pass Canny finds document boundaries even in tricky lighting.
Perspective Correction
Four-point homography maps your angled shot to a perfectly flat, straight document.
5 Enhancement Modes
Magic Color, B&W Document, OCR Optimized, Shadow Removal, and Color — each tuned for a different output goal.
PDF · Searchable PDF · Word · ZIP
Regular PDF, searchable PDF with OCR text layer, Word DOCX, or high-res ZIP images — your choice.
Multi-Page Documents
Upload a whole booklet. Each image is one page — reorder in the strip, bundle into one file.
Private & Auto-Deleted
Files upload over HTTPS, are processed under a random UUID, and deleted automatically after 1 hour.
How to Scan a Document to PDF
Upload your photos
Drop one image per page — HEIC, JPG, PNG, WebP, BMP or TIFF, straight from your camera roll.
Check the crop
Edges are detected automatically. Drag the four corner handles if the document quad needs adjusting, then pick an enhancement mode.
Export
Download as PDF, searchable PDF with an OCR text layer, Word DOCX, or a ZIP of high-res images.
Frequently Asked Questions
Is this a free CamScanner alternative?
Yes — completely free, no watermarks, no account required, no monthly limit. We believe document scanning should be accessible to everyone.
What is Magic Color enhancement?
Magic Color applies CLAHE (Contrast Limited Adaptive Histogram Equalization) in the LAB colorspace to locally boost contrast, then increases saturation and applies an unsharp mask. The result is vivid, pop-off-the-page color — exactly like CamScanner's colour mode.
Why use B&W Document mode?
B&W Document uses adaptive thresholding which handles uneven lighting perfectly — even if one corner is in shadow, text stays black and paper stays white. Best for contracts, invoices, forms, and printed text.
Why did auto detection fail?
Detection works best with clear contrast between the document and background. Common failures: white paper on white desk, heavy shadows, very crumpled document. When it fails, just drag the four corner handles to set your crop manually.
What is OCR Ready mode and when should I use it?
OCR Ready applies NL-means denoising (stronger than bilateral), a tighter adaptive threshold, and morphological cleanup to produce the cleanest possible binary image for text extraction. Use it before running Tesseract, PaddleOCR, or exporting a Searchable PDF. The Extract Text button in the export panel runs OCR directly in the browser using your server.
How does Shadow Removal work?
Shadow Removal uses morphological illumination normalization — it estimates the background lighting map by dilating the image (expanding bright regions to cover dark ones), then normalises each pixel's brightness relative to the local background. No neural network required. It handles gradient shadows from windows or overhead lights very effectively.
Are my documents private?
Yes. Files upload over HTTPS, are processed in a temp directory with a random UUID, and deleted automatically after 1 hour. We never read, store, or share your documents.
Can I upload iPhone HEIC photos?
Yes. HEIC, JPG, PNG, WebP, BMP, and TIFF are all accepted. Upload photos directly from your camera roll on mobile.
