Frequently asked questions
Is there a limit on how many PDFs I can merge?
There is no hard limit, but very large files may be slow on older devices because processing happens in your browser.
Are my files uploaded to a server?
No. PDFSwift processes everything locally in your browser — your files never leave your device.
Can I rearrange the order of my PDFs before merging?
Yes. Drag and drop files in the list to set the order before clicking Merge.
