Questions
Merge PDF questions
Does merging reduce quality?
No. Merging re-writes the document structure only — the original page content, images and vector artwork are copied byte-for-byte.
How many files can I merge at once?
There is no hard limit inside the browser. Practical limits come from your device memory, so hundreds of documents work fine on a desktop.
Are my files uploaded?
No. The merge runs entirely inside your browser. Nothing is transmitted to a server.
