How to Merge PDF Files
Merging PDFs lets you consolidate reports, contracts, invoices, or scanned documents into a single, easy-to-share file. This tool processes everything directly in your browser — your files never leave your device.
Common Use Cases
- Combine scanned documents into one PDF for email submission
- Merge chapters or sections of a report or thesis
- Consolidate multiple invoices into a single finance document
- Combine a cover letter and resume into one application PDF
- Merge bank statements or contracts for record-keeping
Tips for Best Results
- Drag files in the correct order before merging — reordering is easy
- Check individual PDFs are not password-protected before merging
- For very large files (>50MB each), the merge may take a few seconds
Is merging PDFs in the browser safe?
Yes. All processing happens locally in your browser using JavaScript — your PDFs are never uploaded to any server. The merged file is created entirely on your device and downloaded directly. This makes it safer than many online PDF tools that require file uploads to third-party servers.
Can I merge scanned PDFs (image-based PDFs)?
Yes. This tool merges any valid PDF regardless of whether it contains text, images, or scanned pages. Note that scanned PDFs are image-based and won't have selectable text unless they've been OCR-processed. For OCR, you'd need a dedicated tool like Adobe Acrobat or a free online OCR service after merging.
