If you’re trying to compress a large file or folder to email, there’s always waiting: waiting for the original file to compress, for the upload to your email, for your recipient to download, and then unzip it. And that’s not to mention any of the problems that can get in the way, such as duplicated files, corruption, and ZIP and RAR file size limits—and don't even ask about how to condense a video. Sending a large file, without sacrificing file quality, shouldn’t be so hard.
With Dropbox, sending a file or folder in its original size is as simple as clicking Share. No multi-step process needed to compress files to fit in an email. Getting files in Dropbox is a cinch:
(Not all features are available on all Dropbox plans; compare our plans to find the version right for you.)
The second you email a ZIP or RAR file from a file compressor app, anything could happen to your data. All that stands between you and your file getting into the wrong hands is a forwarded email. But with Dropbox, you’re still in control, even after you’ve sent a file, thanks to these and other security features:
It takes precious time to compress a file using file compression software. And who wants to wait around for ZIP files to be created? Dropbox gives you a fast, reliable way to send files with these advanced technologies:
Compressing a file is only half the battle. Once you’ve got your ZIP or RAR file, you still have to put it somewhere. Whether it’s an email, FTP, or file server, your compressed file needs to live somewhere before you can send it. Dropbox takes care of everything in one place, saving you and your recipients the extra steps:
Even if you still need to work with compressed files, Dropbox makes the perfect companion:
File compression—sometimes referred to as data compression—is a way to reduce overall file size to make large files more manageable. It can make large files easier to share or download, and take up less space on your hard drive. Compressed file types are ZIP and RAR most commonly, but can also be ARC, ARJ, or CAB.
File compression works by encoding information into fewer bits than the original by removing redundant data in the file. Most file compression methods are lossless, which means that you won’t lose any data or quality during the compression. Both Mac and Windows devices have file compression features built in to their OS, so you can easily compress your files into zipped folders on your desktop.
Yes, you can upload compressed files—including ZIP or RAR files—to Dropbox. You can:
To unzip files or open RAR files, download them from your Dropbox account to your desktop computer. Since Mac and Windows devices both have built-in file compression features, when you open a ZIP or RAR file for the first time it will automatically uncompress—or unzip—your file.
It’s simple to share or email large files with Dropbox—no need to compress files. Upload the file to Dropbox, create a shared link, and send that link via chat, email, or text to whomever you want. Anyone with the link can view or download the file you’ve shared, even if they don’t have a Dropbox account.
