Flatten PDF: Lock Forms and Layers

Interactive PDFs (with buttons, layers, and fillable forms) can look different on different devices. Flatten PDF merges all these dynamic elements into a single static layer.

Why Flatten?

  • Prevent Edits: Once flattened, form fields are no longer fillable. The data is baked onto the page.
  • Print Compatibility: Complex layers can confuse printers. Flattening ensures what you see is what you print.
  • Speed: Simple, flat PDFs render faster than complex layered ones.
