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.
