Your PDFs never leave your device. Merging runs only in this browser tab.
How it works
Add, reorder, download.
Select two or more PDFs, use the Up and Down controls to set their final order, then merge them into a single file.
Privacy
Your PDFs never leave your device. There is no upload endpoint, account, cloud storage, or server processing.
Limits
Merge up to 30 PDFs, 100 MB each and 500 MB in total, to keep browser memory use practical.
Compatibility
Valid, unencrypted PDFs work best. Password-protected or damaged files cannot be opened in the browser.
