There is no hard limit. You can add as many PDFs as you like. Performance depends on your device's memory, but the tool handles dozens of files efficiently.
Can I reorder the PDFs before merging?
Yes. After adding files, you can drag and drop them to set the desired order before merging.
Does it work on mobile?
Yes. The tool is fully responsive and works on iOS and Android mobile browsers.
Will the quality of my PDFs be affected?
