Dont use this addon, at least they are honest that they require an API on a different server to work.

This addon works offline and because of that is way superior to privacy:

PDF Mage was previously free to use. If you now download a page to PDF, the document is suddenly protected by a password. You can't do anything with it. Unfortunately. It was a good extension. I have removed the extension again.

PDF Mage makes a pretty nice pdf but it is password protected and printing is disabled.

Well, it saves web pages keeping CSS (graphics) and let you select the HTML element you are interested to but the addon require an external server to do the work... so... no thanks

Makes PDF good, but I really don't like the fact that unless I pay this person I can't do anything with the PDF except read it! I don't like being FORCED to pay for something. If it is good people will generally contribute, if not(or they are forced) they won't. I think I'll try a different one.

Unable to print or email

Inutile in quanto non permette poi di stampare il pdf nella versione free

создает скриншот эрана и сохраняет его в pdf. Конечно, по содержимому в компе не отыщите.

It's not that great. It constantly distorts the webpages once converted to PDF. Other extensions I've tried work much better. I'm used to Opera where the option to convert a page to pdf was built right in. Other extensions such as "Print to PDF" work as well as that one did, but not this one.

Saves web pages well as a pdf, does not mention they are password protected. I saved 300, attempted to merge them only to find I couldn't due to the password protection.

When it works, its great, when it doesnt its so disappointing like sometimes you tell it to save the pdf and then when you view the pdf it made its like all white blank :( so disappointing. however when it does work, it gets EVERYTHING nothing is left out which is Great. A lot of screen pdf makers out there, always leave big parts out which pisses me off.

doesn't work on google translate

It doesn't save what you are viewing, but sends the URL from currently opened tab to an external service.

Why is the background of the generated pdf totally black?

Easy to use, but loses some of the original formatting. Using FF57 on Windows.

Won't work...

Error reading current page: chrome.browserAction.setBadgeBackgroundColor is not a function

It's not working on my android phone

Does not function without web access.
In my only try it don't work. I stop it after waiting some seconds.
There is no right click possibility to ask a PDF creation of the web page

This addon works well enough if you are very undemanding. You can't customize the document, before it is created. The built-in PDF printer in Linux is more versatile in this regard. And this addon exhibits the typical Web -> PDF conversion errors: content consumes the whole paper page, i.e. no margin and page breaks cause funny text breaks. Just another example of how insufficient the paper model is in the digital age. My suggestion: ditch it and just save the web page (Ctrl+S).

Edit: Web page content is sent to pdfmage.org. They promise to delete documents after 10 minutes. A privacy policy is missing.
