Select 2 or more PDF files to merge
How It Works
Merge: Upload two or more PDF files, drag to reorder them, then click Merge. All pages are combined into a single downloadable PDF in the order you choose.
Split: Upload one PDF and enter the page ranges you want to extract (e.g. 1-3, 4-6, 7). Each range is saved as a separate PDF file.
Everything runs locally using pdf-lib — your files never leave your device.
FAQ
Is there a file size limit?
No server-side limit. Processing happens in your browser. Very large files (500MB+) may be slow.
Will the PDF quality change?
No. Merge and split operations preserve the original content exactly — no re-rendering or quality loss.
Can I merge password-protected PDFs?
Not currently. Remove the password protection first using your PDF viewer.
