When you need to move media over the internet, use Source-Zip to compress, transfer, and then uncompress the files at lightning speed.

Create self-extracting archives of audio, video, and session files, using industry-standard lossless or lossy codecs.
Every detail about the media is preserved including all the critical metadata.

Optimize file size & media quality with trusted codecs

With a choice of industry-standard codec settings, from Apple Losses (ALAC) to the latest MPEG compression technology, you’ll be able to shrink your files by up to 90 percent for quicker delivery over the internet. Share your self-extracting file via popular cloud storage services or ftp; the recipient simply double-clicks to restore files to full size.

Keep sessions running smoothly when you preserve metadata

When you compress session files with Source-Zip, you can trust that your metadata will be preserved and restored on remote systems, so recipients can quickly re-open sessions, pick up right where you left off and update. Using the uncompressed codec option, return to your collaborators the new audio and session files to complete or continue the collaboration process.

Ensure a seamless file transfer with the free Unzip app

When you compress files with Source-Zip, the recipient can easily unzip them using the free Source-Unzip application included in every archive.

How does it work?

Step 1: Drag the audio or video session folder containing the media files you want to compress into Source-Zip. You can drag the folder directly into the Source-Zip window or onto the Source-Zip icon in the Finder or in the Dock.

Step 2: Choose your desired compression scheme. The greater the compression, the more quality you lose; the smaller the files, the faster they will transfer over the internet. Choose Lossless compression if you don’t want any audio quality loss, or Original if you want to preserve the integrity of your media files.

Step 3: Now, Zip It! Source-Zip will compress all of your audio and video files and create a self-extracting file containing the smallest possible compressed versions of all other files. You will now have a folder containing the compressed audio and video data, along with a free, distributable copy of the Source-Unzip application for the file recipient.

Step 4: Transfer via your preferred cloud storage service, FTP, or otherwise send the .szp file which includes the Source-Unzip application anywhere you like. The person on the receiving end never needs a license to unzip the archive to access the session, and you can send your file to as many people as you wish.

Step 5: To recreate your session on another computer, just drag the .szp archive to the Source-Unzip application. Source-Unzip will recreate an exact replica of your session folder and restore the audio and video files to their original format. If you choose lossless compression, your file transfer is exactly the same as if you transferred your original session.
