Flattening a PDF is the best way to lock in annotations, comments, signatures, and stamps to ensure your file looks exactly as intended.
When you need to share a contract, secure a form, or create a document for public use, flattening your PDF makes everything uneditable. Smallpdf lets you flatten your PDFs in just a few easy steps.
Here, we’ll guide you through the process — from uploading your PDF to enhancing its security once flattened.
Why Flattening Your PDF Matters
Flattening a PDF prevents anyone from modifying elements like stamps, signatures, or annotations. This ensures:
- Document consistency across platforms.
- Protection of sensitive information like personal signatures.
- Peace of mind for formal submissions or public sharing.
Flattening changes your interactive elements into a static layer, making them uneditable and secure.
Now, let's flatten your file step by step.
How to Flatten Comments, Signatures, Stamps, and Annotations in PDF
Step 1: Upload Your PDF
Start by opening Flatten PDF. 1. Click the ‘Choose File’ button or drag and drop your PDF into the upload area. 2. You can also import files directly from cloud accounts like Google Drive or Dropbox. 3. When your PDF is uploaded, the system will process and merge all interactive elements into a single, unalterable layer. 4. Once flattening is complete, download your file by clicking the ‘Download’ button.
