How to send large files online without unnecessary ZIPs
A 2 GB movie file is a very different job from sending a screenshot. It demands reliable network throughput and a browser that can save the incoming bytes without exhausting memory. MallowShare uses WebRTC peer-to-peer transfer where a direct connection succeeds; performance varies by devices and networks.
Understand the real speed limit
If a sender can sustain 10 megabits per second of upload, transferring 2 GiB takes at least about 29 minutes before network overhead. At 100 megabits per second, the theoretical minimum is around 3 minutes. Multiple receivers share the sender's available upload capacity. Faster UI animation does not change network bandwidth.
Choose the right connection
Prefer a reliable fast Wi-Fi network with a strong signal, wired Ethernet when possible, and an uncluttered connection. If sender and receiver are on different networks, direct peer-to-peer connections may fail and a TURN relay may be needed. Some networks block direct connections, so retry on another network if sharing fails.
Check the receiving browser
Browser downloads for big files should use streaming-to-disk capabilities when available. On browsers without direct disk streaming, there may be memory or operating-system limitations. Keep the page in the foreground on mobile to reduce background suspension risk.
Use a room timer intelligently
The room can accept new activity for up to 10 minutes, but a 2 GB transfer may take longer. Start the transfer before the room expires; eligible active transfers may continue through a limited completion grace period. Do not mistake the room timer for a guarantee of transfer speed.
A realistic preflight check
Use MallowShare ShareFit to inspect file sizes locally, enter the measured sender upload speed and receiver count, and get an estimated minimum transfer time. It is a planning aid, not a live speed benchmark. The actual progress indicator is your best reference once transfer begins.
