About Merge PDF

Combine multiple PDF files into one document online for free. No registration, no watermark, instant download.

Best Use Cases

  • Combining a cover letter and CV into one PDF for a job application
  • Merging multiple invoices or receipts into a single document for expense reporting
  • Combining chapters or sections of a document before sharing
  • Putting together a portfolio or proposal from separate files
  • Merging scanned documents that came out as individual pages

Examples

Job application

Drag in your cover letter PDF and CV PDF. Reorder so the cover letter is first. Click Merge. Download the single combined file.

Expense report

Upload January, February, and March invoice PDFs. Merge in order. The result is one PDF with all three months combined for the accountant.

Scanned document

A 10-page document scanned one page at a time produces 10 separate PDFs. Upload all 10, order them correctly, and merge into a single file.

Common Mistakes to Avoid

  • !Not checking the page order before merging - use the drag handles in the file list to reorder before clicking Merge
  • !Merging password-protected PDFs - encrypted files need to have the password removed first
  • !Not compressing the merged file if it is large - a merged PDF containing images can be significantly reduced with the Compress PDF tool after merging

Limitations

  • Bookmarks and internal links from the original files may not be preserved in the merged output
  • The merged file size is roughly the sum of all input files until the compressor is run separately
  • Password-protected PDFs cannot be merged until unlocked

Privacy

All merging runs in your browser using JavaScript. None of your PDF files are uploaded to any server. The merged document is generated and downloaded directly on your device.
