What is PDF Flattening?

  • Lock Fillable Data: Bakes text fields, checkboxes, and signatures directly into static graphics.
  • Prevent Alterations: Ensures contracts and invoices cannot be modified after signing.
  • Clean Rendering: Prevents PDF viewers from misaligning interactive form widgets.

Form Fields vs. Tamper-Proof Raster

  • Form Fields (Recommended): Keeps text sharp and searchable while locking all fillable boxes.
  • Tamper-Proof Raster: Converts each page into a flattened image layer, preventing all text copying and inspection.

Photoshop 7 & 100% Privacy

  • Photoshop 7 Compatible: Output files open cleanly in Adobe Photoshop 7.0+, Illustrator, and all mobile viewers.
  • 100% In-Browser: Layer flattening runs locally via WebAssembly on aphousebd.com; zero server uploads.
