Frequently asked questions
Is there a limit on how many PDFs I can merge?
No. Since everything runs in your browser rather than on a server, the only real limit is your device’s own memory.
Do you upload my files anywhere?
No. The merge happens entirely on your device using your browser’s own processing power. Turn off your Wi-Fi after the page loads and it still works.
Can I change the page order after merging?
Reorder the source files before merging using the up/down arrows or by dragging. Once merged, use the split or rotate tools if you need to adjust the result.
What happens to password-protected PDFs?
A password-protected file can’t be read in the browser without its password, so it’s reported as an error rather than silently skipped. Remove the password first, then merge.
Does merging reduce PDF quality?
No. Pages are copied as-is; nothing is re-rendered or re-compressed, so the result is identical in quality to the source files.
Files are processed locally in your browser and never uploaded. Read more on the privacy page.
