Moved a 2gb video between my laptop and phone on the same wifi in seconds, no signups or upload waits. The offline mode actually works too, which is more than I expected.

 Thanks so much for trying SyntroSend! Really happy to hear the offline mode worked well.I built it to make local transfers as fast and simple as possible, and your feedback means a lot

transferred a 4gb video between my laptop and phone in seconds without signing up for anything, genuinely refreshing.

 Thanks a lot! I'm really glad it worked smoothly for you. We wanted file sharing to feel instant without forcing sign-ups or cloud uploads, so it's great to hear that experience came through.

Finally a file transfer tool that doesn't ask me to sign up or compress my videos into oblivion. Moved a 4GB folder between my laptop and phone in seconds over the same wifi, no weird cloud detour.

 Thanks for giving it a try! That was exactly the experience we wanted—no accounts, no cloud, and no unnecessary compression. Really glad it made transferring your files easier.

Love the no-account, no-cloud approach. One thing that would seal the deal for me: let me set a password on the receiving end for someone to type in before the transfer completes. Right now if a stranger screenshots the link they could grab my file. A simple shared passphrase would make this feel safe to use for actual sensitive stuff.

 Thanks for the thoughtful feedback! That's a great suggestion. A shared passphrase or password protection for transfers and it would definitely add another layer of security for sensitive files. We'll look into adding it in a future update.
