What does flattening a PDF mean?
Flattening converts the PDF so that form fields, annotations, and layers are merged into the page content. The result looks the same but is no longer easily editable—useful when you want to lock in answers, prevent further changes, or reduce file complexity. Flattened PDFs are often smaller and display more consistently across viewers. Processing is done in your browser so your file never leaves your device.
When to flatten a PDF
Use this tool when you need to finalize a form (e.g. after filling it out), remove editable fields before sharing, or create a print-ready version. Upload your PDF above and the tool will flatten it; you can then download the result. No sign-up is required.
