Clean Scanned PDF

Clean scanned PDF pages locally with deskew, auto-rotate, shadow cleanup, noise removal, contrast, grayscale or black-and-white conversion, crop, and before-and-after preview.

Options

Deskew and auto-rotate are local heuristics that apply only when the page signal is confident.

Shadow cleanup, noise removal, contrast boost, grayscale, black-and-white, and crop controls.

Before-and-after preview keeps the source untouched until export.

Output is rebuilt as page images; run OCR PDF afterward if you need searchable text.

FAQ

Are scanned PDFs uploaded?
No. Rendering, cleanup, preview, and export run in your browser.
Does this change my original PDF?
No. The original remains untouched until you download a separate cleaned PDF.
Can cleanup overprocess a scan?
Yes, especially black-and-white mode on faint handwriting or stamps. Use the preview before replacing your working file.
