- Split a PDF by comma-separated page ranges (
1-3, 5, 7-9) - No uploads, no tracking: every byte stays on your device
- Per-file size cap of 50 MB to keep your browser responsive
- Accessible UI with keyboard-reachable controls and clear labels
- Encrypted PDFs are rejected with a clear message instead of silent failure

How To Use
To merge: select two or more PDFs, drag with the arrow buttons to set the order, then click Merge & Download. The result is saved as merged.pdf.
To split: choose one PDF, enter ranges like 1-3, 5, 7-9 (each comma-separated range becomes one output file), then click Split & Generate Files. Download each output individually.
FAQ
Are my files uploaded anywhere?
No. The entire process runs in your browser with pdf-lib. Nothing is sent to a server.
Can I convert PDF to Word (DOCX) or Excel (XLSX)? Not in this tool. Reliable PDF → DOCX/XLSX conversion requires server-side rendering engines that aren’t available on a static site. Use a desktop app or a hosted service for that.
Why does it reject some PDFs? Password-protected or encrypted PDFs can’t be opened in the browser without the password. Remove the password in the source application first.
Is there a file size limit? Each input is capped at 50 MB to keep your browser responsive. Most laptops can comfortably merge a few hundred-page PDFs at once.
Does the page order match what I dragged? Yes. Files are appended in the order shown in the list, top to bottom.
