Frequently asked
Are my PDFs private? Yes — processing is 100% client-side. Files are never sent anywhere.
Does it work with scanned PDFs? Yes. Scanned PDFs (image-based) merge and split just like any other — the tool handles them as pages, not text.
What about password-protected PDFs? Lightly encrypted PDFs often work; heavily password-protected files will fail with an error.
Is there a file size limit? No hard limit — but very large PDFs (100 MB+) may be slow depending on your device's memory.
Frequently Asked Questions
Is the PDF Merger & Splitter free?
Yes — completely free. No account, no subscription, and no file size limit.
Are my PDF files uploaded to a server?
No. Everything runs in your browser using PDF-lib. Your files never leave your device and are never transmitted anywhere.
Do I need an account?
No account, no login, and no email required.
Can I merge more than two PDFs?
Yes. Add as many PDFs as you like, reorder them with the up/down arrows, then click merge.
Does it work with scanned PDFs?
Yes — for merging and splitting. Scanned PDFs are handled as pages, not text, so they merge and split like any other PDF. The Document Converter's PDF to DOCX extraction does not work with scanned PDFs.
What happens with password-protected PDFs?
Lightly encrypted PDFs often work. Heavily password-protected files will fail with an error — you need to unlock them first.
