Local PDF, OCR, and signature workflow

A browser-based process for PDF preparation, text recognition, and visual signature placement.

TPublished by THB Project

Document packets often contain separate PDF files, scanned pages, and photographed forms. A local workflow can prepare these materials without uploading document contents to a conversion service.

1. Prepare the PDF packet

PDF Tools can merge files, extract selected pages, rotate scans, convert images to PDF, and apply a draft watermark.

  • Merge — combine related cover pages, agreements, and appendices.
  • Split — extract only the pages required for a record or submission.
  • Images to PDF — convert legible PNG or JPG scans into a document.

2. Extract text from a scan

OCR — Image to Text downloads a language-processing model on first use and performs recognition on the device.

Input quality requirements

  • Even lighting and strong contrast
  • Accurate cropping around the text region
  • Minimal blur, skew, and compression artifacts
  • Independent review of recognized text before use

3. Apply a visual signature

The Digital Signature tool can create a visual mark and place it on a PDF. It does not provide signer authentication, a digital certificate, an audit trail, or a certified electronic-signature workflow.

Operating considerations

  • Current browser versions are recommended for large PDF operations.
  • Smaller files are generally more reliable on mobile devices.
  • Processing labels should be reviewed before sensitive information is used.

The Background Remover also downloads an on-device processing model on first use.
