Frequently asked questions
Is it safe to merge PDFs here?
Yes. Unlike most online PDF tools, all processing happens locally in your browser using WebAssembly. Your files are never sent to a server, so confidential documents stay private.
How many PDF files can I merge at once?
There is no hard limit on the number of files. Practical limits depend on your device memory — merging dozens of typical documents works smoothly on any modern computer or phone.
Will merging reduce the quality of my PDFs?
No. Pages are copied losslessly into the merged document. Text stays selectable, images keep their original resolution, and no re-compression is applied.
