Frequently asked questions

Is it safe to merge confidential PDFs with this tool?
Files are processed to produce your merged PDF and are not kept afterward — there is no account, no storage, and no one else can access what you upload. For extra-sensitive documents, you can also check your connection is HTTPS (it is) before uploading.
How many PDFs can I merge at once, and is there a file size limit?
You can merge as many files as the batch limit allows, with a per-file size cap enforced server-side to keep the tool fast for everyone. If a file is rejected for being too large, split it first or compress it, then merge.
Can I choose the order the pages appear in?
Yes — reorder the files with the ↑ / ↓ controls before merging. The final PDF follows that exact order, one file after another.
Does merging reduce PDF quality or change formatting?
No. Pages are combined as-is — text stays selectable, images keep their original resolution, and formatting is preserved exactly as it was in each source file.
Do I need to install anything or sign up?
No. It runs entirely in your browser and our server — no software install, no account, no email required.
