Windows File Explorer can't merge PDFs. Edge can't merge PDFs. The Microsoft Store has options, most with limits. The free, fast answer is a browser tab.
The merge flow
Flint's merge tool in Edge or Chrome. Click Add files, pick the PDFs from File Explorer (multi-select with Ctrl). Drag thumbnails to reorder. Hit Merge. Combined PDF downloads.
Thirty seconds for typical jobs. Same flow whether on a Surface, a desktop, or a Lenovo laptop.
Reordering and cleanup
Merged PDF often needs cleanup. Reorder PDF pages if the order isn't quite right. Delete pages for blanks or duplicates. Rotate if any came in sideways. All in the same Flint session, then download the polished result.
Sharing the merged file
After download, attach to Outlook, drop into Teams or Slack, save to OneDrive. Big merged file? Compress first before sending.
FAQ
Is there a limit?
Flint handles dozens of files at a time. The practical limit is total file size — multi-gigabyte merges work but take longer to upload over slower connections. For everyday use, no real limit.
Will bookmarks survive?
Yes. Flint preserves bookmarks and internal links from source PDFs. The merged file behaves as one document with original navigation intact.
Can I do this from File Explorer directly?
Not natively — Windows doesn't have a merge action in the right-click menu. Drag the files into a browser tab on Flint instead. Two seconds slower than a right-click would be, but no install.
Five PDFs, one client. Merge them in the browser and send one tidy file.
