If you're looking to Download WeTransfer on your Chromebook laptop Then read the following guideline.

Drag, drop, and share your biggest files. You can transfer 2GB of files or folders safely and seamlessly around the world with a free account, or log in to WeTransfer Pro to send up to 20GB at a time. Click the icon in your menu bar to choose which files to send, or drag and drop multiple items right onto the icon. You’ll get a download link that you can share with people before the transfer is deleted after seven days. With WeTransfer Pro, you can send without limits — more uploads, larger files, and custom expiration dates.
