A PDF merger with no limits

There is no cap on how many files you can combine or how large they can be — the tool works entirely in your browser, so nothing is uploaded and nothing leaves your device.

The result keeps every page exactly as it was: text stays selectable, links keep working, and images stay sharp.

Merge contracts, scans and photos alike

Combine contracts, invoices, scanned pages, forms and photo PDFs into one tidy file — in whatever order suits you. If a merged file still needs tidying, open it in Organize to reorder pages or the PDF Editor for small fixes.
