Frequently asked questions
Are my PDFs uploaded to a server?
No. All processing happens in your browser. Your PDF data is never sent externally, protecting your privacy.
How many PDFs can I merge?
It depends on the number of pages and file sizes (browser memory limits). If it feels heavy, merge in smaller batches or remove unnecessary pages first.
Can I change the merge order?
Yes. Use the up/down buttons beside each file, or drag to reorder. Files are merged from top to bottom.
Can I merge password-protected (encrypted) PDFs?
Encrypted PDFs may not be readable in the browser. Please use decrypted PDFs before merging.
Can I merge PDFs with different page sizes?
Yes. PDFs with different page sizes can be merged without issues. Each page will retain its original size.
