Solution 1Recommended

Use the Print and Zoom Workaround to Share a Flattened PDF

Since the built-in flatten setting is currently bugged in version 21.06.00, you can bypass it using the system's print preview dialog to manually generate and share a flattened document.

This method utilizes multi-touch gestures available on mobile and tablet versions of the application. By zooming out on the print preview, the operating system effectively renders a flattened image of the document which can then be shared directly.

1
Open the Print Menu

Open your PDF document in Adobe Acrobat, tap the menu icon, and select the 'Print' option.

2
Zoom Out on the Preview

On the print preview screen, place two fingers on the document preview and pinch inwards to zoom out.

3
Share the Document

Tap the 'Share' button that appears at the top of the screen after zooming out.

4
Email the Flattened Copy

Select your preferred email client or messaging application from the share sheet to send the newly generated flattened copy.

Frequently Asked Questions

What does it mean to flatten a PDF copy?

Flattening a PDF merges interactive elements like annotations, form fields, and digital signatures directly into the background of the document. This prevents further editing and ensures the document's appearance remains identical across all viewing devices.

Why is the flatten setting not working in Adobe Acrobat version 21.06.00?

This is a known software glitch specific to version 21.06.00 where the application fails to execute the flatten command during the share process. Until an official patch is released, users must rely on workarounds like the print preview method.

Can I flatten a PDF on a desktop computer if the mobile app fails?

Yes. On a desktop computer, you can use the 'Print to PDF' feature within your PDF viewer to create a brand new, flattened version of your document, which you can then save and manually attach to an email.
