Frequently Asked Questions
How many PDFs can I merge at once?
You can merge as many PDFs as you like — there is no hard limit, just your browser's available memory.
Is there a file size limit?
Each individual file must be under 50 MB. The combined output size is limited only by your browser's memory.
Does merging PDFs keep the original quality?
Yes. Pages are copied directly without re-encoding, so quality is identical to the originals.
Can I merge password-protected PDFs?
No. Please remove the password from your PDFs before merging. You can do this in Adobe Acrobat or your PDF viewer.
Are my files uploaded to your server?
Never. All processing runs entirely in your browser using JavaScript. Your files never leave your device.
