Frequently asked questions
Common questions about the Merge PDF.
Can I combine images into the PDF too, not just other PDFs?
Yes. You can drop in images alongside PDFs and they become pages in the merged document.
Can I reorder the pages before merging?
Yes — drag the files and pages into the order you want, and you can also rotate or delete any individual page before downloading.
Are my PDFs uploaded to a server?
No. The merge runs in your browser, so your documents never leave your device — important for contracts, statements and other sensitive files.
Is there a limit on how many files I can merge?
There is no fixed file-count limit, but because the work happens in your browser, very large or numerous files are bounded by your device's memory.
Will merging reduce the quality of my pages?
No. Existing PDF pages are combined as-is without re-compression, so text and images keep their original quality.
