Merge PDF

Combine multiple PDF files into a single document. You can merge entire files in a specific order, or switch to Page Mode for granular control over individual pages from every uploaded PDF.

How It Works

  1. Upload two or more PDF files by clicking the drop zone or dragging them in.
  2. Choose between File Mode and Page Mode using the toggle at the top.
  3. In File Mode, drag files to reorder them and optionally specify page ranges (e.g., 1-3, 5) for each file. Leave the range blank to include all pages.
  4. In Page Mode, drag and drop individual page thumbnails to build your exact page sequence.
  5. Click Merge PDFs to combine everything into one file. The merged PDF downloads automatically.

Features

  • Two merge modes: File Mode for quick whole-file combining, Page Mode for per-page control
  • Drag-and-drop reordering in both modes with smooth animations
  • Page range syntax (e.g., 1-3, 5, 8-10) lets you cherry-pick pages without switching to Page Mode
  • Lazy-loaded page thumbnails keep the UI responsive even with large documents
  • No limit on number of files or total page count
  • Preserves original PDF quality with no re-encoding

Options

Pages inputPer-file text field accepting ranges like 1-3, 5 to include only specific pages

Use Cases

  • Combining separate chapter PDFs into a single book or report
  • Merging a cover letter and resume into one application document
  • Pulling specific pages from multiple source documents into a consolidated file
  • Assembling scanned receipts or invoices into one archive PDF
  • Creating a presentation handout from slides across multiple decks

Tips

  • Use Page Mode when you need to interleave pages from different files rather than appending one file after another.
  • You can add more files after the initial upload using the Add More Files button without losing your current arrangement.
  • Page ranges are 1-indexed, so 1 refers to the first page of that file.
