I’m thinking about using LocalSend to transfer files between my devices, but I’m not sure how reliable, fast, or secure it is in everyday use. I’d really appreciate help from anyone who has used LocalSend for local file sharing and can share what worked, what didn’t, and whether it’s worth trying.
I started using LocalSend because I wanted a quick way to move files between my devices without relying on cloud storage or cables. If you haven’t heard of it, LocalSend is a free, open-source app that lets you transfer files over your local network. No internet required, everything stays within your Wi-Fi.
What I liked right away:
- It’s easy to set up, I installed it and started sending files in minutes
- No accounts or logins, which is refreshing
- Transfers are usually fast when everything works as expected
For simple file sharing between devices on the same network, it really does the job.
Where Things Started Getting Annoying
After the initial smooth experience, I ran into a few issues that seem pretty common among users.
The biggest one was connectivity. Sometimes my devices just wouldn’t see each other. I’d have both apps open, same Wi-Fi, and still nothing. It turns out things like firewalls, router settings, or even having a VPN turned on can block LocalSend completely. I had to fiddle with firewall permissions more than once, which isn’t something everyone wants to deal with.
Then there are file transfer quirks. Sending individual files usually works fine, but folders can be hit or miss. I got permission errors a couple of times when trying to send folders between Windows machines. The error messages didn’t really explain what was wrong, so I had to guess and retry.
Cross-platform transfers can also be inconsistent. For example, I could send files from my Windows laptop to my Android phone, but sometimes the reverse just wouldn’t work. It’s not constant, but it happens enough to be frustrating.
Security Concerns I Noticed
I personally didn’t run into any major issues here, but I’ve seen people raise concerns about how secure LocalSend is, especially the web version. Since it operates on your local network, the risks depend a lot on your environment. If you’re on a shared or less secure network, it’s something to think about.
Like any tool, it’s fine if you understand how it works, but it’s not something I’d blindly trust in every situation.
Why I Sometimes Use Something Else
LocalSend is great when it works, but I realized that a browser-based or Wi-Fi-based solution isn’t always enough, especially when you’re transferring large files or a lot of them.
If your connection is unstable, transfers can fail halfway through, and that’s the worst moment to lose files. I’ve had transfers stall or restart, and with slower networks, it can take forever.
That’s why I ended up trying MacDroid with a USB cable.
My Take on MacDroid
MacDroid is a desktop app designed to connect Android devices to Mac, letting you transfer files directly through a cable instead of relying on Wi-Fi or the internet.
What I like about it:
- It connects your Android phone to your Mac like a regular drive
- You can drag and drop files both ways
- It works over USB, so you’re not depending on network stability
- It handles large files and big batches without slowing down
Using a wired connection avoids a lot of the issues I had with LocalSend. No random disconnects, no waiting on slow uploads, and no worrying about cloud storage limits or missing files.
For me, it solved:
- Slow transfers over Wi-Fi
- Paying for extra cloud storage
- Files failing or disappearing during transfer
Final Thoughts
I still keep LocalSend installed because it’s convenient for quick transfers, especially when everything is on the same network and behaving properly. But for bigger tasks or anything important, I’ve found myself reaching for a wired solution more often.

I’ve used LocalSend on Windows, Android, and Linux for a few months. My take is a bit more positive than @mikeappsreviewer’s, at least for normal day to day stuff.
For small and medium files, it works well. Photos, PDFs, APKs, docs, short videos. Setup is fast. No account. No cloud. Open app, pick device, send. That part is solid.
Speed depends on your network, not magic. On decent 5 GHz Wi-Fi, I usually saw transfers move fast enough to beat messaging apps and cloud sync by a lot. On weak Wi-Fi, it gets flaky. If your router is crowded or one device drops to 2.4 GHz, you feel it fast.
Reliability is mixed, but not bad. Device discovery sometimes fails. I found two fixes helped most:
turn off VPN
make sure your firewall lets LocalSend through on private networks
After I did that, it was much smoother. So I don’t think LocalSend is unreliable by default, I think home network setups are messy and LocalSend exposes that mess.
Security wise, I’d use it on my home network without stress. I would not use it on hotel, school, or shared apartment Wi-Fi for private files. Local network does not mean trusted network. Big difference.
Where I agree with @mikeappsreviewer is large transfers. If you’re moving huge folders, backups, or stuff you cannot afford to redo, wired is still safer. If you’re on Mac and Android, MacDroid is a better pick for those bigger jobs. USB is boring, but boring is good when you need files to arive intact.
Short version:
LocalSend is good for quick local sharing.
It is not perfect.
It’s worth installing.
Keep a wired option too, esp for large batches.
I’m somewhere between @mikeappsreviewer and @sonhadordobosque on this.
LocalSend is legit useful, and for everyday stuff it’s probly one of the nicer no-account tools around. I use it for screenshots, PDFs, installers, random photos, that kind of thing. In that role, it’s very good. Open app, send file, done. No cloud delay, no compression nonsense, no emailing yourself like it’s 2012.
Where I kinda disagree with the doomier takes is reliability. On a normal home network, once it’s allowed through the OS security prompts, it’s mostly fine. Not flawless, but not some unstable mess either. The real issue is that LocalSend depends heavily on your network behaving properly. If your Wi-Fi is weird, guest-isolated, or your devices keep sleeping aggressively, LocalSend gets blamed for stuff that isn’t fully its fault.
Speed is decent to great, depending on Wi-Fi quality. Not magic, just network-bound.
Security? Fine on trusted home Wi-Fi. I would not use it casually on public/shared networks for sensitive files. “Local” does not automatically equal “safe,” and people forget that.
My actual verdict:
- Great for quick day-to-day transfers
- Pretty painless once set up
- Occasional discovery hiccups still happen
- Not my first choice for huge folders or important one-shot transfers
For bigger jobs, I still prefer wired. If you’re on Mac + Android, MacDroid is honestly the more dependable option for large file transfer, especially when you want stable USB file transfer without babysitting the process. LocalSend is the handy screwdriver. MacDroid is the power drill.
I land somewhere between @sonhadordobosque and @techchizkid, and a little apart from @mikeappsreviewer on one point: I think LocalSend is at its best when you treat it like a convenience tool, not a file management system.
My real-world take:
Where LocalSend shines
- quick sends between phone and laptop
- no sign-in nonsense
- open source is a nice bonus
- great for photos, notes, installers, PDFs, short clips
Where it gets annoying
- device discovery can be temperamental
- background battery saving on phones can interrupt things
- big transfers feel like a gamble if your Wi-Fi is inconsistent
- folder handling is still less confidence-inspiring than plain old wired transfer
I slightly disagree with the idea that it’s only as good as your network. That’s mostly true, but apps also matter in how gracefully they handle interruptions, retries, and sleep states. LocalSend is decent, not bulletproof.
Security
Fine on your own home network for normal stuff. I would not casually push sensitive files over shared Wi-Fi just because it says “local.”
My rule
- small/medium everyday transfers: LocalSend
- large batches, media dumps, or anything important: cable
If you’re doing Mac + Android, MacDroid is worth a look for the second category.
MacDroid pros
- stable USB-based transfers
- better for huge files and bulk copying
- Finder-like workflow feels more predictable
- less dependent on Wi-Fi weirdness
MacDroid cons
- not as instant as tapping send over the air
- cable required
- more useful for a specific Mac/Android setup than general all-device sharing
- not the best choice if you want one app for every platform equally
So yeah, LocalSend is worth installing. Just keep expectations realistic. It’s a very handy drawer tool, not the one tool I’d trust for every job.
