How the differences affect the job
Start with the file, the people receiving it, and what needs to happen after delivery.
The first step is almost the same
Both services let you choose files, upload them, and share a link without signing up. Neither asks the person downloading a public transfer to create an account. That makes both useful for a quick one-off handoff.
The free size is the clearest difference
storage.to allows up to 25 GB for free. TransferSize allows a file up to 50 GB. Both free links can expire within one to seven days, so tell the recipient when the link will stop working.
Simple and limited can be a good choice
storage.to focuses on temporary upload, link, and share. That shorter workflow may be all you need. TransferSize adds a workspace, history, previews, receive links, paid downloads, and account tools, which also means there is more to learn.
Their extra tools serve different users
storage.to offers a desktop app, command-line tool, and API. TransferSize offers read-only WebDAV on eligible plans, plus creator tools and Live Relay. Choose the tools you will use, not the longest feature list.
