Watch nothing get sent anywhere.
Most "free" PDF mergers upload your file to a server you can't see, in a country you didn't pick, under a privacy policy you didn't read. This one has zero network requests after the page loads — check the Network tab yourself, right now, before you trust it with anything.

No accounts
No signup, no email, no watermark. Use it and close the tab.
No limits (for now)
Merge as many files as your device's memory allows. No artificial 3-file caps.
Splitting, rotating, reordering, compressing, and numbering PDFs? All live too.
Extract pages or split every page into its own file, fix pages scanned sideways, drag pages into a new order, shrink the file size, or stamp page numbers onto every page — same rule: everything stays local. Leave your email and we'll let you know about a Pro batch mode.
Thanks — saved locally for now, we'll be in touch once signups are live.
