Merge PDF
Open the first document, append the others, and every page lands in one continuous file you can reorder before exporting. Pages are copied across with their original content intact, so nothing is re-encoded on the way through.
Whichever document should lead is the one to open first — though you can reorder everything later, so it is not binding.
Add each further PDF from the editor. Its pages join the end of the current document and appear in the page rail on the left.
Drag thumbnails to reorder, or select a page and use Alt with the arrow keys. Rotate or delete anything that arrived the wrong way round.
Download writes a single PDF containing every page in the order shown.
Merging lifts each page's existing content across to the new document rather than rasterising and recompressing it. Text stays selectable, vector art stays sharp, and image quality is whatever it was in the source.
Most merge tools give you a fixed file-level order and nothing more. Here the merged document is just a document: reorder, rotate, duplicate or drop individual pages before you export.
The documents are combined in the browser, which means the practical ceiling is your device's memory rather than an upload limit or a queue.
A calm, fast PDF workspace. Free to use, private by default.
