Questions people ask
Are my files uploaded to a server?
No. Merging happens inside your browser on your own device and no file is sent anywhere.
How many files can I merge?
STAK sets no limit. The real limit is your device’s memory, and very large files take longer.
Does it work with a password-protected PDF?
Locked files cannot be opened here; remove the password in your PDF reader first, then merge.
