Documentation

The PDF riding seal tool splits a seal image into page-based slices and places them on the selected PDF edge locally in your browser. It is useful for contracts, bids, scans, archives and submitted documents.

Key Features

  • Upload one PDF and a PNG, JPG or WebP seal image.
  • Stamp all pages or a custom page range.
  • Place the split seal on the right, left, top or bottom edge.
  • Use forward or reverse slice order for different binding and scan workflows.
  • Adjust alignment, seal size ratio, page margin and opacity.
  • Review the page slice plan, progress, output file name and output size.

Steps

  1. Upload the PDF that needs a riding seal.
  2. Upload the seal image. Transparent PNG is recommended.
  3. Set page range, edge, slice order, size ratio, margin and opacity.
  4. Generate the riding seal PDF and wait for local processing.
  5. Review the slice plan and download the output file.

Page Range

  • Leave the range blank to stamp all pages.
  • Use single pages and ranges such as 1,3-5,8.
  • Page numbers must be within the current PDF page count.

Use Cases

  • Add riding seals to contracts, agreements and authorization files.
  • Prepare bids, quotations and submission PDFs before delivery.
  • Process scanned files, archives and internal approval documents.
  • Keep sensitive PDF and seal assets local without uploading them.

Privacy

This tool reads the PDF, slices the seal image and creates the output file in your browser. It does not actively upload your PDF or seal image to a server.
