The majority of file hosting websites make use of captchas when free account users or guests try to download files from their servers. For me, that's more of a way to make the downloads less convenient to convince more users to upgrade to a premium account. Still, there is not much you can do if you need to download a file from the hosting server.

I already mentioned earlier today that I like to use the JDownloader software to download files from file hosting services. It is more convenient, especially since it saves the download queue so that downloads can be resumed at any time. Captchas on the other hand still need to be filled out. That's a problem if you need to leave the computer for a longer period of time, or if you do not want the captchas to disturb you from other computer activities.

Ghacks reader KoalaBear suggested to use the plugin Captcha Trader for automatic captcha solving. The service is offered as a plugin for JDownloader, MiPony and a handful of other popular downloaders. It basically allows the user to either buy credits or solve captchas in advance so that captchas in JDownloader are resolved automatically by the plugin.

Here is how Captcha Trader works.

  • Visit the Captcha Trader website and create an account.
  • Switch to the Plugins directory on the site and download the plugin for your software and operating system. I'm going to demonstrate how to add the plugin to JDownloader. Readme files are included that explain how the plugins are installed.
  • Extract the folder and copy it to the \JDownloader\jd\captcha\methods\ folder.
  • Edit captchatrader.properties with a text editor and add your username and password to the file.
  • Restart JDownloader.

The plugin will not show up in JDownloader. It won't work right away since you do not have any credits in the beginning. That is, unless you have bought credits on the site. 10000 credits on the site, good for at least 1000 solved captchas cost $6 Dollars.

Instead of paying, users can earn credits by solving captchas on the Captcha Trader website. A click on Earn Credits displays a captcha every 50 or so seconds. Solving the captcha correctly will award credits to the account.

Users earn seven credits for text recognition captchas, and three for image recognition captchas. It costs ten credits to solve text captchas, and five credits to solve image recognition captchas.

It is furthermore possible to cash out at anytime. 10000 credits equate $1.

Once you got enough credits, captchas are automatically resolved in the software you use to download files from file hosts. The captcha should not pop up anymore which is great if you need to work full screen.

Update: Captcha Trader seems to have been discontinued and we are not aware of any free solution that works with JDownloader at the moment.

      Well it is a bit difficulty to distinguish between name.com domains and files for instance.

    The comments section under this very article (3 comments) is identical to the comments section found under the following article:

    Not sure what the issue is, but have seen this issue under some other articles recently but did not report it back then.

    With the cloud, there is no such thing as unlimited storage or privacy. Stop relying on these tech scums. Purchase your own hardware and develop your own solutions.

      This is a certified reddit cringe moment. Hilarious how the article’s author tries to dress it up like it’s anything more than a png for doing the reddit corporation’s moderation work for free (or for bribes from companies and political groups)

    With Google Chrome, it’s only been 1,500 for some time now.

    Anyone who wants to force me in such a way into buying something that I can get elsewhere for free will certainly never see a single dime from my side. I don’t even know how stupid their marketing department is to impose these limits on users instead of offering a valuable product to the paying faction. But they don’t. Even if you pay, you get something that is also available for free elsewhere.

    The algorithm has also become less and less savvy in terms of e.g. English/German translations. It used to be that the bot could sort of sense what you were trying to say and put it into different colloquialisms, which was even fun because it was like, “I know what you’re trying to say here, how about…” Now it’s in parts too stupid to translate the simplest sentences correctly, and the suggestions it makes are at times as moronic as those made by Google Translations.

    If this is a deep-learning AI that learns from users’ translations and the phrases they choose most often – which, by the way, is a valuable, moneys worthwhile contribution of every free user to this project: They invest their time and texts, thereby providing the necessary data for the AI to do the thing as nicely as they brag about it in the first place – alas, the more unprofessional users discovered the translator, the worse the language of this deep-learning bot has become, the greater the aggregate of linguistically illiterate users has become, and the worse the language of this deep-learning bot has become, as it now learns the drivel of every Tom, Dick and Harry out there, which is why I now get their Mickey Mouse language as suggestions: the inane language of people who can barely spell the alphabet, it seems.

    And as a thank you for our time and effort in helping them and their AI learn, they’ve lowered the limit from what was once 5,000 to now 1,500…? A big “fuck off” from here for that! Not a brass farthing from me for this attitude and behaviour, not in a hundred years.
