Clean, lightweight PDFs
Drag and drop files or folders to strip hidden elements, annotations and markups from PDFs in one pass - fully offline.
Process one file or hundreds at once - drop in a folder and it scans automatically.
Originals stay untouched. Flattened versions are saved alongside them with “_flattened” appended.
Everything happens on your machine, so your documents stay private throughout.

PDF Flatten is a Windows desktop app, free to try from the Microsoft Store.
Not yet - PDF Flatten currently uses its own separate sign-in. It's on the list to move onto the same shared account already used by Vector and Forma.
Anyone who needs to strip hidden layers and markups out of PDFs before sharing them, without uploading documents anywhere.
