Use Adobe Acrobat on the Web

Click the 'Sign In' button at the top right corner and enter your Adobe ID and password to access your cloud workspace.
Click 'Select a file' or drag and drop your PDF into the browser window to begin viewing, commenting, or editing your document securely in the cloud.
Install the Official Adobe Acrobat Desktop App
Replace the unsupported, unofficial portable version with the official Adobe Acrobat desktop installation for maximum stability on Windows 10.

Frequently Asked Questions
Is there an official portable version of Adobe Acrobat?
No, Adobe has never released an official portable version of Acrobat. Any 'portable' versions found online are unofficial, unauthorized modifications that may be incomplete, unsafe, or contain malicious software.
Why did Acrobat XI Portable stop working after installing Windows 10?
Acrobat XI is older, discontinued software. Unofficial portable versions rely on specific system files, dependencies, or registry configurations that are strictly managed or entirely removed by modern Windows 10 security protocols.
Can I run Adobe Acrobat from a USB flash drive without installing it?
The official desktop version of Adobe Acrobat requires a full local installation on your computer's hard drive to function properly and cannot be run directly from a USB drive. If you need portability, use Adobe Acrobat online via a web browser.
Are unofficial portable PDF apps safe to use?
No. Unofficial portable copies often bypass licensing checks, do not receive critical security updates, and can expose your system and sensitive documents to severe security risks and data theft.
