Good to know
Do my PDFs get uploaded anywhere?
No. Merging happens with JavaScript running in your browser tab. Your files never touch a server — you could disconnect from the internet after the page loads and it would still work.
What order do the pages end up in?
Files are merged top-to-bottom in the order shown in the list, with each file's own pages kept in their original order. Use the up and down arrows to reorder files before merging.
Will this work with password-protected PDFs?
No — encrypted or password-protected PDFs can't be read in the browser. Remove the password first, then merge.
Is there a file size or count limit?
There's no limit we impose — you're only bound by your device's memory. A handful of PDFs is no problem; a very large batch or very large files may take a few seconds longer, or run slower on an older phone or laptop.
