What merging actually does
Every page from each file is copied, untouched, into one new PDF. Text stays selectable, links and page sizes are preserved, and nothing gets re-compressed, so quality is identical to the originals.
When it won't work
Password-protected PDFs can't be read until they're unlocked. If one file in the batch is damaged, we'll tell you which one so you can remove it and carry on.

Questions people actually ask
How many PDFs can I merge at once?
Up to 50 files, each up to 100 MB. The real limit is your device's memory, so very large batches are faster in a desktop browser.
Will merging reduce quality?
No. Pages are copied as-is. If you need a smaller file afterwards, run it through Compress PDF.
Can I change the page order inside a file?
Merge keeps each file's pages in order. To shuffle or delete individual pages, use Organize PDF after merging.
Do you upload or keep my files?
No. Processing happens inside your browser, so your file never reaches our servers. Close the tab and it's gone.
