Filemark Maker is a tiny Mac application that converts files into data URLs which you can bookmark and then open on the iPhone. The best thing about Filemarks is that they work even when your iPhone is offline, so if you're in the subway or on an airplane, you can still view your files. It's technically not a widget (yet!) though it's really easy to use.

1: Download the Filemark Maker droplet beta.

2: Drop a file onto it and it will open a page in Safari with a link to the bookmark. It supports .doc, .xls, .rtf, .txt, .jpg, .jpeg, .png, .gif, .pdf, or .html.

3: Add that link to your Safari bookmarks and sync it to your iPhone with iTunes

4: Open Safari on the iPhone and open the Filemark!

Why can't you just bookmark your Filemarks on the iPhone? You need to bookmark them on your computer and then sync. Trying to bookmark a Filemark on the iPhone may cause Safari to crash.

Are there file size restrictions? We haven't found specific size limits, but the iPhone seems to dislike loading really big images...we crash consistently when we load a 4000 pixel wide image! We've had no problems reading pdf's of books on the phone, though!

Will Filemarks work in Airplane mode? Yes! The data is all local, so you can open your Filemarks even if you can't get to the internet.

PS:This is freeware - we can't be responsible for anything you do with it. Nobody is really sure what the effects of having giant bookmarks are going to be on Safari on your computer. It's probably smart to back up your bookmarks before you try to push the limits of what you can save with this!
