Frequently asked questions
Is it safe to merge confidential PDFs here?
Yes — safer than server-based tools. Your files are processed locally with WebAssembly and are never uploaded, so there is nothing to leak.
How many PDFs can I merge at once?
There is no fixed limit. Merging runs on your own device, so very large batches just take a bit longer.
Will bookmarks and links be preserved?
Page content is preserved exactly. Document-level metadata like outlines is simplified in the merged file.
