The Easiest Way to Combine PDF Files Using PurePDF (merge pdf)

Combining PDF files is a common task—reports, invoices, contracts, or scanned pages often need to be joined into a single document. PurePDF makes merging PDFs fast, secure, and simple. This tutorial covers the merge-pdf tool (CLI and UI), includes numbered steps, quick tips, and FAQs so you can produce a clean combined PDF in minutes.

Why use PurePDF to merge PDFs?

• Speed: Merge large files quickly with optimized processing.
• Privacy: Local processing (no upload) keeps your documents private.
• Quality: Preserves original page quality, bookmarks, and metadata.
• Flexibility: Command-line and graphical workflows, batch support, and page reordering.
• Cross-platform: Works on Windows, macOS, and Linux.

Quick overview (one-line)

Command-line: purepdf merge-pdf -o combined.pdf file1.pdf file2.pdf

GUI: Open PurePDF > Tools > Merge PDF (merge-pdf) > Add files > Arrange > Merge.

Detailed step-by-step: Merge PDFs with the PurePDF GUI

1. Open the PurePDF application and navigate to the "Tools" or "merge-pdf" section.
2. Select the Merge PDF tool.
3. Click "Add Files" or drag-and-drop your PDFs into the file list. You can add entire folders for batch merging.
4. Arrange files in the desired order by dragging them up or down. Use the thumbnail view to verify pages.
5. (Optional) Select page ranges for each file if you only want to merge specific pages.
6. Choose output options: filename, output folder, whether to keep metadata, and whether to linearize for fast web viewing.
7. Click "Merge" and wait for the process to complete. PurePDF shows progress and notifies you when the combined PDF is ready.
8. Open the merged output, verify page order and quality, and save or share.

Detailed step-by-step: Merge PDFs with the PurePDF CLI (merge-pdf)

1. Install PurePDF or confirm the binary is in your PATH.

2. Open your terminal or command prompt.

3. Run a basic merge command:

   bash purepdf merge-pdf -o combined.pdf invoice1.pdf invoice2.pdf report.pdf

4. To merge all PDFs in a folder:

   bash purepdf merge-pdf -o combined.pdf ./pdf-folder/*.pdf

5. To merge with specific page ranges and order:

   bash purepdf merge-pdf -o combined.pdf fileA.pdf:1-3 fileB.pdf fileC.pdf:5-10

6. For batch merging (multiple outputs at once) use a manifest or script with the CLI to automate repetitive merges.

Useful command options (examples)

• -o, --output FILE : Specify output filename.
• --range FILE:START-END : Merge specific page ranges (syntax varies by version).
• --preserve-metadata : Keep original document metadata.
• --linearize : Optimize the PDF for fast web viewing.

(Use purepdf merge-pdf --help to list exact flags for your installed version.)

Quick Tips

• Tip 1: Preview thumbnails before merging to avoid page order mistakes.
• Tip 2: Use page ranges to exclude cover pages or duplicate content.
• Tip 3: If files are large, enable linearization or compression to reduce final size.
• Tip 4: Keep a copy of original PDFs until you confirm the merged file is correct.
• Tip 5: Use the CLI in scripts to automate monthly or weekly report merges.

PurePDF benefits highlighted

• Privacy-first: Local processing means files never leave your machine unless you choose to upload them.
• Speed & efficiency: Optimized merging reduces wait times even for large documents.
• Preservation: Maintains original quality, bookmarks, and metadata so nothing is lost.
• Versatility: Both GUI and CLI make PurePDF suitable for non-technical users and power users alike.
• Automation-ready: CLI options let you integrate merging into build pipelines or scheduled tasks.

FAQs

Q: Can I merge password-protected PDFs? A: Yes—use the GUI prompt or CLI flag to supply the password(s) when merging encrypted PDFs. If a PDF is locked for editing, you may need the owner password.

Q: Will PurePDF change my file quality or compress images? A: By default, PurePDF preserves original quality. You can enable compression or image downsampling if you want a smaller file.

Q: Can I reorder pages after merging? A: Yes. In the PurePDF GUI you can reorder pages before merging. If you need to reorder after merging, use the "Reorder Pages" or "Organize" tool.

Q: How big can the merged PDF be? A: PurePDF can handle large PDFs, though final size depends on source content (images vs. text). Use compression or remove unnecessary images to reduce size.

Q: Is there a limit to how many files I can merge at once? A: Practically, limits are determined by available memory and disk space. For very large batches, merge in groups or use batching scripts.

Q: Does PurePDF preserve bookmarks and metadata? A: Yes—PurePDF supports preserving bookmarks and metadata; enable the preserve option if needed.

Final checklist before merging

• Confirm page order and ranges.
• Decide whether to preserve metadata and bookmarks.
• Choose output location and file name.
• Verify passwords for encrypted files.
