Frequently asked questions
Are my files uploaded to a server?
No. This tool runs entirely in your browser using local processing — your files never leave your device, which also makes conversion instant with no upload wait.
Is there a limit on file count or size?
No artificial limits. Everything is processed in your browser's memory, so very large batches (hundreds of MB) depend on your device — typical documents merge instantly.
Will links and bookmarks survive the merge?
Page content, images and embedded fonts are preserved exactly. Document-level extras like bookmarks/outlines are not carried over — a common limitation of client-side merging.
