FAQ
Is my file uploaded?
No. Everything runs in your browser with pdf-lib — files never leave your device.
Is there a file count limit?
No hard cap, but merging 20+ large files may slow the browser — especially on mobile.
Can I reorder files?
Yes. Use the ▲ / ▼ buttons next to each file. The merged PDF pages follow the list order.
Are encrypted PDFs supported?
Not in V1. Password-protected PDFs raise an error — remove protection first.
Do bookmarks and links survive the merge?
V1 preserves only page content — document-level bookmarks, form fields and link annotations may be dropped.
