What the PDF Merger Does and Why It Matters
The PDF Merger combines several PDF files into one document, in the order you arrange them, entirely inside your browser. It reads each file with the pdf-lib library on your device and writes a single merged PDF you can download β no upload, no account.
This matters because related material so often arrives as separate PDFs: a contract and its appendix, scanned receipts, or chapters of a report. Stitching them into one ordered file makes the set easier to send, archive, and print as a single unit.
How to Use PDF Merger
- Add the PDF files you want to combine.
- Drag them into the order you want pages to appear.
- Run the merge to assemble one combined document.
- Download the merged PDF and open it to confirm the order and page count.
Supported Inputs and Limitations
What you provide
- Two or more PDF files from your device
- The desired order of the files
What you get
- A single PDF containing all pages in your chosen order
- A downloadable file ready to share or print
Known limitations
- Total size is bounded by your device memory; very large sets (the page suggests up to ~50MB) may be slow.
- Password-protected or corrupted PDFs may need to be unlocked or repaired first.
- It joins whole files; to pick specific pages, use the PDF Splitter first.
Privacy and Security
Merging happens entirely in your browser using pdf-lib. Your PDFs are read on your device and are never uploaded to NovaTools or any external server, so confidential documents stay private.
Frequently Asked Questions
Can I control the page order?
Yes. Arrange the files before merging and pages are combined in exactly that order. Use the splitter first if you need to reorder individual pages.
Is there a size limit?
There is no server limit because nothing is uploaded, but practical size is limited by your device memory; the tool targets files up to roughly 50MB.
Are my files uploaded?
No. The merge runs locally and your documents never leave the browser.
