About PDF Merging
Combining long reports and scattered scans into a single PDF keeps your paperwork tidy. Our merger runs offline in the browser, so the original formatting and metadata stay untouched.
How the merger works
- Sequential page stitching that respects the order you set
- Direct page copying without recompression or layout shifts
- Integrity checks for corrupted pages before they are appended
- Local processing that never uploads confidential documents
Why our PDF merger stands out
Manual order control
Drag files up or down and the merger stitches pages in the exact sequence you choose.
Preserved metadata
Page sizes, links, and bookmarks pass through untouched, so the final file behaves like the originals.
On-device privacy
Merging happens locally, which means contracts, invoices, and NDAs never leave your laptop.
PDF merge FAQs
Can I change the page order before merging?
Yes. Rearrange files in the list and the merged PDF will follow the updated sequence automatically.
Is there a size or page limit?
Each document can be up to 100 MB. There is no fixed page limit, although very large files may require a few extra seconds to finish.
Does the merger remove duplicate pages?
No. The merger copies your documents exactly as provided. If you add the same file twice it will appear twice in the final PDF.
Are my documents uploaded anywhere?
No. Merging happens entirely in the browser, so nothing is sent to external servers.
