How the differences affect the job
Start with the file, the people receiving it, and what needs to happen after delivery.
These services are built for different workloads
TransferSize fits a one-off browser send or a smaller workspace. MASV is built for teams that move very large media packages over and over. Decide whether this is one delivery or part of a production pipeline.
Free does not mean the same thing
TransferSize allows a file up to 50 GB without a card. MASV includes 15 GB of transfer credit each month, but asks for a card and moves to usage billing after the credit is used. Check the billing model before a large job starts.
No package limit solves a different problem
MASV does not set a package-size ceiling on its current plans. That helps with multi-terabyte media and data work. TransferSize has clear per-file limits, topping out at 1 TB on Business.
Automation can save more time than upload size
MASV has a desktop Agent, watch folders, an API, Portals, and many storage integrations. Those tools matter when the same workflow runs every day. TransferSize keeps the workflow smaller, with browser uploads, receive links, read-only WebDAV, and Live Relay.
