Scan and clean document photos with perspective correction, deskew and batch output
Import or capture up to 30 pages, auto-detect page edges, edit four draggable corners, perspective-correct and rotate locally, then optionally estimate text skew or apply manual deskew.
Use color/grayscale/global-or-adaptive black-and-white thresholding, brightness/contrast/shadow cleanup, median noise reduction and sharpening; detect likely duplicate pages; reorder/remove pages; choose A4/Letter/Legal/custom/DPI/format/image quality/PDF JPEG compression; export an active image, ZIP batch or multi-page PDF; and save/import scanner presets as JSON.
- Edge detection + four-corner perspective correction + deskew
- Adaptive threshold + noise/shadow/sharpen cleanup
- Duplicate-page detection + reorder/remove/batch
- DPI/page-size/quality/PDF compression + reusable presets
