Use This Tool Free — No SignupFlatten your PDF documents instantly with our free online tool — no signup, no software, no hassle. The flattener converts all interactive elements in your PDF to static content, making the document view-only and print-ready. This is particularly useful when you have filled out a PDF form and want to lock in the entries, when you need to share an annotated document without allowing further annotations, or when you are archiving documents that should not be modified. The tool runs in your browser and processes documents quickly. Upload your PDF with form fields, annotations, or other interactive elements, and download a clean, flattened version. The flattened PDF is fully compatible with all PDF viewers and printers, and the file size often decreases since interactive element data is removed.
