Why SizeFix DocCleaner is the #1 CamScanner Alternative

Capture documents with your phone camera under poor bedroom or office lighting. Our client-side morphological AI engine normalizes lighting in real-time, bleaches dirty paper to pure 100% white, darkens faint ballpoint ink, and exports crisp PDF files without watermarks.

Shadow Bleach
100% Pure White

Instant AI Document Shadow Removal & Paper Bleaching

Smartphone photos of documents often suffer from harsh finger shadows, mobile flash glare, and dim yellow room lighting. DocCleaner runs an advanced morphological closing algorithm directly inside your browser memory to calculate low-frequency background lighting maps and bleach muddy, grey paper into crisp 100% printer-white sheets in under 50 milliseconds.

  • Automatically detects and neutralizes finger shadows, phone angles, and yellow light cast
  • Bleaches crumpled, old, or yellowed paper into clean official submission-ready white
  • Smooth split comparison slider to inspect raw camera snapshot vs clean bleached document
Deep Black Ink
Official Stamp Pop

Deep Black Text Enhancement & Official Stamp Preservation

Unlike crude photocopy scanners that wash out colored stamps or turn documents into illegible grainy black-and-white, DocCleaner features an intelligent chroma-isolation mask. It darkens faint ballpoint pen strokes and typed fonts to jet black while preserving the rich natural colors of blue signatures, purple office seals, and red revenue stamps.

  • Power-gamma ink steepening curve restores faded ballpoint ink and light printer text
  • Preserves official blue signatures, purple tehsildar seals, and red government stamps
  • Precision spot eraser brush to cleanly remove staple marks, punch holes, and stray dust
4-Corner Deskew
1-Click Auto-Detect

4-Corner AI Perspective Deskew & Document Straightening

Documents photographed at angles on tables, beds, or vehicle seats appear warped as uneven trapezoids. DocCleaner provides interactive 4-corner corner pins with real-time SVG polygon guides. Our inverse projective bilinear warp calculates the homography transformation to eliminate tilt and stretch the document into a perfectly flat, rectangular scan.

  • 4 interactive corner pins with live dashed SVG boundary polygon overlay
  • 1-Click Auto-Detect document bounds isolates paper from cluttered room backgrounds
  • High-resolution bilinear math straightens slanted pages without blurring characters or text

Frequently Asked Questions

How does SizeFix remove shadows without erasing printed text?
SizeFix uses a client-side morphological closing algorithm to model the low-frequency illumination map across the paper. By dividing the original photo by this background map and applying a steep gamma power curve, shadows and folds are bleached to 100% pure white while dark ink strokes and typed fonts are intensified to jet black.
Are my confidential government IDs saved on any server?
Never! SizeFix is engineered strictly as a client-side HTML5 Canvas application. Whether you are scanning an Aadhaar card, PAN card, marksheet, or legal property agreement, every single pixel is processed inside your browser RAM. No image data is ever sent across the network.
How does the 4-Corner Perspective Crop fix angled photos?
When you photograph a document lying on a table, the perspective is typically distorted into a trapezoid. Our 4-Corner Crop tool lets you drag 4 corner handles to the actual document corners. An inverse projective bilinear warp calculates the homography transformation and stretches the polygon into a clean, flat, rectangular document.
Will it preserve blue signatures and official government stamps?
Yes! Traditional photocopy filters turn everything into harsh black-and-white, completely destroying blue ink and purple seals. SizeFix includes a chroma-retention mask that detects blue ballpoint ink and red/purple stamp pigments, boosting their natural saturation while bleaching the surrounding paper.
How do I erase unwanted fingers, punch holes, or staple marks?
Click the "Spot Eraser" tool in the toolbar. A precision circular brush ring appears on your document. Simply brush across unwanted thumbs, binder clips, edge stains, or staple holes to paint them into pure white. You can adjust the brush size and opacity or click Undo at any time.
Can I combine multiple document pages into a single A4 PDF?
Yes! Use the "Multi-Page Batch" upload button or click "+ Add Next Page" in the sidebar. You can review page thumbnails, adjust each page individually or click "Apply Settings to All Pages", and click "Export Multi-Page PDF" to print or save a combined A4 PDF document.
Does SizeFix place any watermarks on exported PDFs?
Zero watermarks! Unlike mobile apps like CamScanner that insert annoying footer watermarks unless you purchase a subscription, SizeFix gives you 100% clean, professional, submission-ready documents completely free.
