Question details

The user needs to prevent Acrobat Distiller from automatically launching when downloading an Adobe Illustrator (.ai) file from a browser.

How to Stop Acrobat Distiller Opening When Downloading AI Files
Product
Adobe Illustrator / Acrobat Distiller
Device & OS
not provided
Scenario
Downloading an AI vector graphic file from the internet via a web browser.
Observed behavior
Acrobat Distiller automatically opens the file instead of saving it normally or opening it in Adobe Illustrator, likely due to incorrect file associations or browser automation settings.
Before you start

Ensure that Adobe Illustrator is currently installed on your computer and verify that the downloaded file actually ends with the '.ai' extension rather than '.pdf'.

Solution 1Recommended

Change the Default Application for AI Files

Reassign the .ai file extension in your operating system so it opens with Adobe Illustrator by default instead of Acrobat Distiller.

Often, installing new Adobe software or PDF tools can accidentally hijack the file associations for vector files. Correcting the default app will ensure AI files route to Illustrator.

1
Locate the downloaded file

Open your File Explorer or Finder and navigate to your Downloads folder to find the downloaded AI file.

2
Open the file properties

Right-click on the AI file. On Windows, select 'Open with' and then click 'Choose another app'. On Mac, select 'Get Info'.

3
Set Illustrator as the default

Select 'Adobe Illustrator' from the list of applications. Make sure to check the box that says 'Always use this app to open .ai files' (Windows) or click 'Change All' (Mac), then apply the changes.

Change the Default Application for AI Files
Association Fixed: Future AI files will now feature the Illustrator icon and open in the correct workspace automatically.

Frequently Asked Questions

Why are my AI files showing as PDF icons in my folder?

This happens when your operating system's default program for AI files gets changed to a PDF reader like Acrobat Distiller or Adobe Reader. You can fix this by right-clicking the file, selecting 'Open with', and setting the default application back to Adobe Illustrator.

Can I disable Acrobat Distiller from starting automatically?

Yes, check your browser's download settings to ensure it isn't set to automatically open PDF or PostScript files. You can also check your system's startup applications and disable Distiller from running in the background.

Does renaming the file extension from PDF to AI fix the issue?

If the file was incorrectly saved by the browser as a PDF but contains original Illustrator data, renaming the extension from .pdf to .ai might help Illustrator recognize it. However, if the issue is just an OS file association, changing the default app is the correct and permanent solution.
