FAQ

Frequently asked questions

Is there a limit on how many PDFs I can merge?
No fixed limit — you can combine as many files as your browser can hold in memory. Very large batches may be slower on older devices.
Are my files uploaded anywhere?
No. Merging happens entirely in your browser using JavaScript, so your documents never touch a server.
Will merging change the quality of my PDFs?
No. Pages are copied exactly as-is, so text, images, and formatting are preserved.
