Jak używać Scan to PDF
Convert camera photos or dark PDFs into crisp, shadow-free, high-contrast document PDFs.About scan to PDF
Convert camera photos or dark PDFs into crisp, shadow-free, high-contrast document PDFs. Turn phone photos of receipts, signed pages, whiteboard notes, or forms into clean office-grade scans.
Extreme perspective distortion from angled camera shots is not unwarped automatically; crop the image or shoot straight-on for best results.
How PDFolio helps you scan to PDF
PDFolio applies adaptive luminance thresholding and contrast stretching to every page or image on an HTML5 canvas, whitening paper backgrounds while sharpening dark ink strokes.
If you want to combine photos into a PDF without altering their lighting or contrast, use JPG to PDF.
Before you download
Use Magic Color when the document has colored stamps, highlights, or blue ink signatures you want to keep in color.
When the result is ready, download it immediately and open it in your usual PDF viewer to make a final check. You can then use Clear task data to release temporary file references from this browser tab. PDFolio does not create an account, cloud folder, or server-side document history.
A private way to scan to PDF
PDFolio handles the selected files in the active browser tab. A Web Worker on your device performs the PDF task so the interface can remain responsive; document bytes are not sent to a PDF processing server, upload queue, account database, or advertising platform.
Kroki

- Choose Crisp B&W Document (adaptive threshold), Magic Color (contrast boost), or Grayscale Deskew.

Warto wiedzieć: Crisp B&W Document mode removes uneven paper lighting and gray phone shadows so pages print cleanly without wasting toner.
Najczęstsze pytania
How do I remove gray background shadows from a phone photo of a document?
Select the Crisp B&W Document filter—it turns uneven gray paper backgrounds pure white while keeping text sharp.
Can I upload an existing PDF scan to clean it up?
Yes. Scan to PDF accepts both image files (JPG/PNG) and existing PDFs.
Does scan to PDF change my original file?
No. PDFolio creates a new file for download. Your source file remains unchanged on your device.
