Verify the Email and Update Your PDF Application

Confirm the legitimacy of the Adobe retirement announcement and securely switch to the supported application through official channels.

Adobe has officially retired the standalone Adobe Fill & Sign application. All its form-filling and signature features have been integrated into Acrobat Reader Mobile.

If you previously installed Fill & Sign and logged in with an Adobe ID, the email you received from mail@mail.adobe.com is a legitimate notification from Adobe.

Verify sender email

Check the sender's address in your email client to ensure it is exactly mail@mail.adobe.com without any misspellings or extra characters.

Check official announcements

Open your web browser and search for 'Adobe retires Fill & Sign: Switch to Acrobat Reader' to read the official confirmation directly on Adobe's website.

Download supported app securely

Open the Apple App Store or Google Play Store on your device, search for 'Adobe Acrobat Reader', and install the official app instead of clicking email links.

Remove retired software

Locate the old Adobe Fill & Sign application on your home screen and uninstall it, as it will no longer receive security updates.

Safe Transition: By directly using your device's official app store, you completely bypass any risk associated with malicious email links.

Frequently Asked Questions

Can I still use the Adobe Fill & Sign app if I don't uninstall it?

While the app might continue to work temporarily, it is officially retired and will no longer receive security updates or support, meaning it may eventually stop functioning on newer mobile operating systems.

Why did I receive this retirement email if I haven't used the app recently?

Adobe sends these notifications to any user who previously downloaded the Fill & Sign app and logged in with their Adobe ID, regardless of how recently the app was used.

Are my previously signed documents lost after the app retirement?

No, documents saved locally on your device or backed up to Adobe Document Cloud remain safe. You can access your cloud-saved files by logging into a supported PDF reader with the same Adobe ID.
