Frequently Asked Questions

How many PDF files can I merge at once?
You can merge as many PDF files as you need. Simply add all your files to the upload area, arrange them in order, and merge them in one step.
Is there a file size limit?
For best performance, we recommend keeping individual files under 100MB. Very large PDFs may take longer to process depending on your device's hardware.
Will merging PDFs reduce quality?
No. The merge process combines your files without re-compressing or altering the content. Images, text, and formatting remain exactly as they are in the originals.
Are my PDF files secure?
Yes. All processing happens locally in your browser. Your files are never sent to or stored on any external server.
Can I merge PDFs on my phone or tablet?
Yes. The tool works on any modern browser, including Safari and Chrome on iOS and Android.
Can I merge a PDF with a Word document?
This tool merges PDF files only. If you need to combine a Word doc with a PDF, first convert it using our free Word to PDF converter, then merge the result here.
What's the difference between merging and combining PDFs?
They mean the same thing. Merging, combining, joining, and concatenating PDFs all refer to taking multiple separate files and producing one unified document.
