Locked, final copies

Flatten and lock PDFs for final audit packs and records

Turn a finished PDF into a locked, flattened copy so its formatting cannot be changed and further edits are stopped. Useful for final audit packs and records you need to keep exactly as they were.

How it works

How to flatten a PDF

  1. Finish your edits first: combine, reorder, redact and compress as needed.
  2. Open Rasterize and Flatten PDF from Document Tools.
  3. Choose the finished PDF.
  4. Create the flattened copy and download it.
  5. Store it as your final version, and keep the editable original separately.
Why it matters

Built for final versions

Final means final

Formatting is locked down and further edits are stopped, so the version you filed is the version people read.

Made for audit packs

Assemble the pack with Combine Files, then flatten the result into a single locked file.

A new copy, not an overwrite

Flattening produces a new file, so you can keep the editable original.

Know the trade-off

Rasterising turns each page into an image, so the text is usually no longer selectable or searchable. Keep the original for anything that needs searching.

Accountability

Every action is tied to the staff member who ran it and timestamped. Output files are automatically deleted after a set retention window, so you stay audit-ready without the file clutter.

Common questions

Rasterize and Flatten PDF FAQ

What does rasterize and flatten mean?

Each page is rendered as an image and merged into a single layer. The document looks the same, but its contents can no longer be edited like normal text.

Will I still be able to search or select the text?

Usually not, because the text becomes part of the page image. Keep the original file if you need a searchable copy.

Is flattening the same as redaction?

No. Redaction permanently removes the content you choose. Flattening locks the whole document. If a file needs both, redact first, then flatten.

Is a flattened PDF a digitally signed document?

No. Flattening stops further edits, but it is not a digital signature or a certificate of authenticity.

Will the file get bigger?

It can, because pages are stored as images. Run Compress PDF afterwards if you need a smaller file.

Who can use it?

Access is controlled in Admin Tools. You decide which staff can use Document Tools.
