: Idle ~180MB, editing a large PDF ~450MB. Acceptable. CPU usage : OCR spikes to 70-80% on all cores. Otherwise, low. Battery life : On a laptop, continuous PDF editing drains battery ~15% faster than Edge or Firefox PDF viewer.

The Fill & Sign tool is excellent. You can create fillable forms automatically (Acrobat detects form fields with decent accuracy). The e-signature workflow (Send for Signature) integrates with Adobe Sign. On Windows 11, the interface for adding recipients and tracking signatures is clear, though it requires a subscription (included in Pro DC).

You can host a shared PDF review where multiple users comment. On Windows 11, the comment pane is responsive. However, for real-time collaboration, you’re better off using Microsoft Edge’s built-in PDF annotator or a dedicated tool like OneDrive’s PDF viewer.

In Acrobat > Preferences > General, enable “Use new experience for Recent Files” and under “Security (Enhanced)”, turn on Protected View for all files. Then in Windows 11 Settings > Default Apps, set Acrobat only for PDFs you need to edit—use Edge for reading to save battery.

Export to Word, Excel, PowerPoint, or JPEG. Word export on Win11 kept 95% of layout—tables, columns, and footnotes survived. Excel export turned a PDF table into a usable spreadsheet, but merged cells can be messy. Conversion speed is fast; a 20-page PDF to Word took ~8 seconds.

A hidden gem: Compare two PDFs. It highlights text changes, images, and formatting. On Win11, this runs quickly and is invaluable for legal or contract work. 3. Performance on Windows 11 (Real-world tests) Test system: Dell XPS 13 Plus (i7-1260P, 16GB RAM, SSD, Win11 Pro 22H2)
