Questions
Is there a page limit?
There's no fixed page limit, but very large files depend on your device's memory. On phones, keep files under ~50 MB each.
Does merging change quality?
No. Pages are copied as-is — text stays selectable and images keep their original quality.
Is my file uploaded?
No. Your file is processed entirely in your browser and is never uploaded to a server.
