There are many Web tools that let you store the Web files directly to your Dropbox. Here are a couple of them.
1.URL Droplet
This is one of the Web apps that can be used to save your download files to the Dropbox account without having to download them on your PC. Visit the tool from the link https://www.urldroplet.com/ and sign up on it using your Dropbox credentials. It will ask you to grant permission to access your Dropbox profile. Grant the permission and the Web tool will present you the input box to enter the required URL. That's it, the file will now be saved to your Dropbox account.
2. Sidecloudload
This is yet another Web tool that works the same way as URL Droplet. Once you visit their website and register with your Dropbox credentials and grant access permission, you just need to enter the URL of your download link in the box provided. Select Save or Save as as per your needs. The file gets saved to your Dropbox.
Well, these are just a couple of representative tools you may use to save your downloads directly to your Dropbox account. There are other tools that work on the same principle. Make sure that the download links are publicly accessible. If not, the tools will not work.
If you do not want to use third party Web tools, you may choose to opt for Chrome extension. Here is how you can do it.
1. Locate the Download to Dropbox chrome extension from Chrome Web store or from the link https://chrome.google.com/webstore/detail/download-to-dropbox/mklccdhnpppcmbpbkaanmamjfmmefbnp
2. Add the extension to your chrome installation. 3. Access the extension by navigating to tools and extensions. Find the extension you just added and click on it.
4. Login using your Dropbox credentials. Grant permission to access your Dropbox account when asked to do.
5. That's it - now whenever you want to save a copy of the file to your Dropbox, right click on the link. You should get Upload to Dropbox option. Click on it and your file is saved to your Dropbox.
The extension is also available for Firefox.
There is another extension that does work similarly, but it has an additional functionality that lets you transfer files to different cloud services apart from Dropbox. Use the Cloud Saveextension for this purpose. Here is how you do it -
1. Find the extension Cloud Save from Chrome Web store or the link https://chrome.google.com/webstore/detail/cloud-save/dlbemabjbfhjcccahjioenmkgimjbbkd?hl=en
2. Add it to Chrome as you normally would do with an extension.
3. Now, when you find something worth saving to your cloud storage, right click on the item.
4. You should find an option Cloud Save. Selecting it will provide you a list of cloud services you can save your file to. Actual number of options shown depends on the nature and type of the file. Click on the desired destination.
5. Authorise the app to use the selected storage service by providing your credentials and granting access permission. Be careful when authorising. You may need to reinstall the extension if you set something wrong.
The extension supports quite a big number of services which includes Picasa, Flickr, Posterous, Facebook, Imgly, Box.net, SugarSync, Dropbox, Google Docs, Amazon Cloud and DropIr.
