How to Stop Acrobat from Randomly Generating or Downloading PDFs
Question details
The user needs to prevent Adobe Acrobat from repeatedly attempting to generate PDFs or download images when viewing documents, which causes slow performance.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Viewing or interacting with existing PDF documents in Adobe Acrobat.
- Observed behavior
- Acrobat displays vague messages about generating PDFs and downloading images, accompanied by slow redraws and poor preview performance.
Ensure you save your current PDF files and take note of the menus, as you will need to modify core preference settings and restart Adobe Acrobat.
Disable 'Create PDF from Web Page' Preferences
Turn off the automatic web-conversion settings in Acrobat that trigger background generation and slow down the application.
The background generation messages typically stem from Acrobat's 'Create PDF from Web Page' feature trying to process web content. Disabling the automatic downloading of elements like images can stop this behavior.
Launch Adobe Acrobat, click on the Edit menu at the top of the window, and select Preferences. Alternatively, you can press Ctrl+K on your keyboard.
In the Preferences dialog box, look at the left-hand panel and click on the Convert to PDF category.
Select HTML or Web Page from the list of formats, click the Edit Settings button, and uncheck any options related to automatically downloading images or rich media.
Click OK to apply the changes, close the Preferences window, and restart Adobe Acrobat to see if the random generating messages stop.

Optimize Page Rendering Settings
If disabling web conversions does not fully fix the slow redraws, try adjusting the hardware acceleration and page display rendering settings.
Use WPS PDF for Fast, Glitch-Free Viewing
If Adobe Acrobat continues to suffer from slow redraws and unwanted web-conversion tasks, you can open and read your PDFs instantly using WPS Office. It provides a highly optimized, lightweight PDF reader that won't randomly generate or download web content in the background.
- 1. Download and Install: Download the free version of WPS Office from the official website and follow the simple installation instructions.
- 2. Launch WPS PDF: Open WPS Office on your computer and click on the 'PDF' tab from the main dashboard.
- 3. Open Your Document: Click 'Open', select your existing PDF file, and enjoy seamless viewing without any background lag or automatic downloads.

Frequently Asked Questions
Why does Acrobat say it is generating a PDF when I am already viewing one?
This usually occurs if you interact with an embedded web link inside the document or if Acrobat's 'Create PDF from Web Page' feature is automatically trying to process HTML elements attached to the PDF.
How can I speed up slow PDF redraws and preview performance?
You can improve rendering speeds by going to Edit > Preferences > Page Display in Acrobat, and adjusting the 'Use 2D graphics acceleration' and 'Smooth text' settings based on your system's hardware.
Is there a way to permanently stop Acrobat from downloading images?
Yes, you can prevent auto-downloading by modifying the Convert to PDF settings in the Preferences menu. Selecting HTML and unchecking the options for downloading multimedia and images stops this background behavior.
