Frequently Asked Questions
Is this PDF merger really free?
Yes, completely free! There are no hidden charges, no subscription fees, and no limitations on the number of PDFs you can merge. We don't even require registration or email sign-up.
How many PDF files can I merge at once?
You can merge up to 10 PDF files simultaneously. For larger batches, we recommend merging in groups and then combining the results.
Is there a file size limit?
There's no hard limit, but extremely large files (100+ MB) may slow down processing depending on your device's memory. For optimal performance, we recommend files under 50MB each.
Can I reorder PDF pages after merging?
Our tool merges complete PDF files in the order they appear in your list. For page-level reorganization, you might need a PDF editor after merging.
Will the merged PDF lose quality?
No, the merger preserves the original quality of all PDF files. Text remains selectable, images retain their resolution, and formatting stays intact.
Does this work on mobile devices?
Yes! Our PDF merger is fully responsive and works perfectly on smartphones and tablets. The interface adjusts automatically to your screen size.
What happens to my files after merging?
Nothing is stored. Your original files remain on your device, and the merged file is downloaded to your computer. We don't keep any copies.
