PDF Merge — FAQ
Are PDFs uploaded?
No. Selected files are read and merged in the current browser tab.
Does merging change page quality?
Pages are copied rather than rasterized, so content is not intentionally recompressed.
Can encrypted PDFs be merged?
Not reliably. Use an authorized unlocked copy before merging.
