Frequently Asked Questions
Instant answers to common questions regarding security, performance, and usage.
Is there a limit on files?
Only your browser RAM limits the amount. Most modern systems can merge 50+ documents at once.
Can I merge password-protected files?
You must unlock the individual files first using our PDF Unlock tool before merging.
Will the file size be too large?
Merging doesn’t add bulk. For smaller output, use our PDF Compressor after merging.
