We have a downloadable PDF file which looks great at 72% magnification in Adobe Reader and not so good at 101%. When downloaded and opened in the reader, its default magnification is 101%.
Is there a way to define the default magnification in the PDF file itself so that we ensure the best user experience?
Thank you!
If you can control the URL used to download, you can put parameters in the URL to control how the built-in reader will display the file.
For example, http://example.org/doc.pdf#zoom=50 will set the magnification to 50%.

The above applies to the built-in reader supplied by Adobe. Other readers may not honor the parameters. In particular, see the answer to this question regarding Chrome.
