If you are looking for a quick way to upload and share files temporarily, TMP.link is the way to go. Best of all, you don’t need to sign up. Upload a file of up to 50 GB and share it. There is unlimited temporary space for 24 hours. The app has three sharing modes. Limited time-sharing allows users to enjoy a free and unlimited number of files that expire after 24 hours. Auto-renewal sharing will enable you to define an expiry date. Persistent sharing (the paid version) has dedicated storage space without expiration. The app comes with CLI support which is a big plus (upload via CURL).
Users can manage the uploaded files by creating and (of course) logging into the account. Files can be organised, categorized and searched.
To download, scan the QR code or via the command line. There is no limit to downloads either.
