2 Ways to Increase the Font Size in a CHM File – wikiHow

With Microsoft Internet Explorer 7 or later, you can make web pages easier to read by enlarging the page (zooming in). If you zoom in, everything on the web page will be magnified (including text, images, and controls). Zoom will change the magnification of the website, regardless of the format of the website. I just installed IE7 and since then I can no longer change the font size in existing chm files. I can usually do this by pressing {ctrl} + {mouse wheel}. This is really a bummer, because the fonts get so small that all my documents became totally unreadable.

Is there a fix/solution? Here are two ways to increase the font size in a Windows Help (CHM) file

1. Use the Firefox plugin to read the chm file in Firefox

CHM Reader is a Firefox extension that makes compiled HTML files viewable directly with Firefox. After installation, with “File | Open CHM File”, you can open a CHM in Firefox. With “View | Sidebar | CHM Reader” or press “Ctrl-E”, the sidebar containing the list of CHM topics and indexes will be displayed. Then you can use the page zoom functionality in your Firefox.

2. Using ChmZoomer (strong recommendation)

chmzoomer gives you handy full page zoom functionality in all other browser based applications like Chm files, eBooks, RSS reader etc. You can open Chm with the official chm reader on Windows and get the page zoom functionality you like in IE7/8.

The shortcut keys are the same as those in IE and Firefox. Press [CTRL +] Prayed [CTRL Mouse wheel up] to zoom Press [CTRL -] Prayed [CTRL Mouse wheel down] to drive away Reset the zoom to 100% with Ctrl-0. Visit below to take a tour of the software. Enjoy!
