Processes scanned PDFs with OCRmyPDF: deskews pages, rotates, cleans noise, despeckles, removes borders. Use to fix skew, artifacts, and improve quality before OCR.

[OCRmyPDF](https://github.com/ocrmypdf/OCRmyPDF) includes powerful image processing capabilities to improve scan quality before OCR. These tools help fix skewed pages, remove noise, clean borders, and enhance readability.
Creates isolated Git worktrees for feature branches with prioritized directory selection, gitignore safety checks, auto project setup for Node/Python/Rust/Go, and baseline verification.
Executes implementation plans in current session by dispatching fresh subagents per independent task, with two-stage reviews: spec compliance then code quality.
Dispatches parallel agents to independently tackle 2+ tasks like separate test failures or subsystems without shared state or dependencies.

Deskew corrects pages that are slightly rotated (e.g., from feed scanner skew).
# Auto deskew (recommended)
ocrmypdf --deskew input.pdf output.pdf
# Force deskew even if rotation is minimal
ocrmypdf --deskew --force-ocr input.pdf output.pdf
Rotate pages to correct upside-down or sideways scans:
# Auto-rotate based on text orientation
ocrmypdf --rotate-pages input.pdf output.pdf
# Force rotate all pages
ocrmypdf --rotate-pages --force-ocr input.pdf output.pdf
Remove unwanted borders, artifacts, and noise from scanned pages:
# Remove borders (dots, solid borders)
ocrmypdf --remove-bordering input.pdf output.pdf
# Combine with cleanup
ocrmypdf --remove-bordering --clean input.pdf output.pdf
Remove speckles and isolated noise pixels:
# Remove speckles
ocrmypdf --despeckle input.pdf output.pdf
# Aggressive despeckle for very noisy scans
ocrmypdf --despeckle --clean input.pdf output.pdf
unpaper provides advanced post-processing:
# Apply unpaper with default settings
ocrmypdf --unpaper input.pdf output.pdf
# Custom unpaper board options
ocrmypdf --unpaper-args "--board A4" input.pdf output.pdf
Increase image resolution before OCR for better accuracy:
# Oversample to 300 DPI before OCR
ocrmypdf --oversample 300 input.pdf output.pdf
# Common for low-resolution scans
ocrmypdf --oversample 400 input.pdf output.pdf
ocrmypdf --deskew --remove-bordering --despeckle scanned.pdf fixed.pdf
ocrmypdf --deskew --rotate-pages --despeckle --clean --oversample 300 noisy.pdf clean.pdf
ocrmypdf --remove-bordering --unpaper --despeckle dirty.pdf clean.pdf
