Sixty pages merge in about a second because there is no queue to wait in. Your originals are never modified, so an ordering mistake costs one more click, not the file. If you use it often, install it from the Edge or Chrome menu: it opens in its own window, keeps working offline once loaded, can be chosen as the app that opens PDFs from File Explorer, and can save every result straight into a folder you pick instead of the Downloads pile. For pages interleaved between documents, Mix pages lays every page of every file on one board.
How it works
- Open Bindery in Edge, Chrome or Firefox and drop the PDFs anywhere
- Arrange them on the board — each shows its first page
- Click “Merge locally” and download the combined file
Questions people ask
Do I have to install anything on Windows?
No. Bindery runs as a web page in any current browser. Installing it from the browser menu is optional and gives you an app window, offline use once loaded, “Open with Bindery” for PDFs in File Explorer (Edge and Chrome) and saving straight into a chosen folder.
Are the merged pages changed in any way?
No. Pages are copied into the new document exactly as they were — text stays selectable, images keep their resolution, form fields and links come across. Merge also writes a real outline so each source file gets a bookmark in the result.
Is it really free?
Yes. All 47 tools are free, with ten completed jobs per UTC day and no file-size cap of Bindery’s own; there is no watermark and no account. Pro is $5 a month for unlimited jobs and synced recipes, and is not needed to merge files.
