How to Fix Acrobat Zooming Out When Typing in a PDF Form
Question details
The user experiences an issue where typing specific characters into a Fill and Sign field causes the document to zoom out unexpectedly.

- Product
- Adobe Acrobat Pro DC
- Device & OS
- macOS Mojave
- Scenario
- Filling out a PDF document using the Fill and Sign tool.
- Observed behavior
- Typing triggers the autofill suggestion list, which repeatedly reduces the document zoom level and disrupts the form-filling process.
Ensure you have your Acrobat or Document Cloud account credentials handy, as you will need to sign in to your account settings to adjust the autofill preferences.
Disable Autofill Suggestions in Account Settings
Turning off the autofill word or phrase suggestions prevents the suggestion dropdown from triggering the unexpected zoom reduction.
The zooming glitch is directly tied to the autofill suggestion interface popping up when specific letter combinations (like 'HA') are typed. Disabling this feature stops the UI conflict and keeps your zoom level stable.
Open Adobe Acrobat and sign in to the Acrobat or Document Cloud account associated with your software.
Navigate to your account profile or preferences menu and select 'Settings'.
Locate the autofill settings and disable the option to suggest words or phrases in the autofill list.
Close and reopen Adobe Acrobat to ensure the new settings are applied to your Fill and Sign tool.

Frequently Asked Questions
Why does my PDF zoom out when I type certain letters?
This is often caused by a glitch related to the autofill suggestion feature in the PDF software. When the suggestion box pops up for specific letter combinations, it forces the document view to resize.
Can I clear my autofill history instead of disabling it?
Yes, clearing previous autofill entries in your software's preferences (usually under 'Forms' or 'Auto-Complete') may temporarily resolve the issue without requiring you to disable the feature entirely.
Does this zoom issue happen on Windows as well?
While this specific bug was prominently reported on macOS Mojave, similar autofill display glitches can occasionally occur on Windows depending on the software version and system scaling settings.
