Frequently asked questions
How do I combine PDFs without Adobe?
Drop your PDF files above, drag them into the order you want, and click Merge. You get one combined PDF instantly — no Adobe Acrobat, no software install, no account.
Is it free to merge PDFs here? Is there a limit?
Yes, completely free and unlimited. Merging runs in your own browser, so there are no server costs to pass on — no hourly task limits and no file size limits, unlike most online PDF tools.
Is it safe to merge sensitive PDFs online?
With this tool, your files are never uploaded anywhere. The merge happens entirely inside your browser using WebAssembly — contracts, medical records, and financial documents stay on your device.
Can I change the page order of the merged PDF?
You control the file order by dragging the file cards before merging. To reorder or remove individual pages afterwards, use the Split tool to extract exactly the pages you need.
Why does this tool have no upload limit?
Because there is no upload. Tools that process files on a server must limit size and frequency to control costs. Since merging runs on your device, we don't need any limits.
