Share Files Over Wi-Fi Without Cables or the Cloud
You don't need a cable, a shared cloud folder, or an upload to share files over Wi-Fi between your own devices. If your phone, tablet, or computer are on the same Wi-Fi network, Sync's built-in web server turns one of them into a local file server the others can browse from any web browser — no app install on the receiving end, no internet connection required. Here's how it works and what it's actually good for.
What you need
- Two devices on the same Wi-Fi network — the one sharing the files (running Sync) and the one receiving them (just needs a web browser).
- The Sync app, on the device doing the sharing.
- That's it. The receiving device doesn't need Sync installed at all — a browser is enough.
Turning on the web server
Open Sync and start the Web Server. It picks the files or folders you choose to share, then gives you a local web address — something like an IP address and port on your own network. That address only works for devices connected to the same Wi-Fi; it's not reachable from the internet.
Connecting from another device
On the second device, open any browser and type in the address Sync shows you. You'll see a folder listing of whatever was shared — click a file to download it, or browse into folders if more than one was shared. If a shared folder happens to contain an index.html file, Sync serves that automatically instead of a plain file list, which is handy if you're sharing something meant to be viewed rather than downloaded.
Because the server supports partial content, larger files and video don't need to download in one shot — a receiving browser can resume a stalled download or start playing a video before it's fully transferred, the same way streaming from a real web server works.
Free vs. paid
The web server works on the free tier, with one limit: free lets you serve one file, up to 200 MB, at a time. That covers plenty of one-off transfers — a document, a handful of photos zipped together, a PDF. Sharing more than one file at once, sharing whole folders, or removing the 200 MB cap is part of Sync's paid upgrade — the same subscription or one-time lifetime purchase that unlocks every cloud drive, USB and external drive support, and an ad-free app.
A few things worth knowing
- It's local-network only. Nothing is uploaded anywhere — the files stay on your device and get served directly to whoever's on the same Wi-Fi. That's the actual advantage over emailing yourself a file or bouncing it through a cloud drive: no upload step, no waiting, no account needed on the other end.
- Device support: the web server is available on iPhone, iPad, Android, and Mac. It's not currently available on Windows — if you're moving files to or from a Windows PC, USB and external drives or a shared cloud drive are the better options there.
- It's a manual, on-demand feature. You turn it on when you want to share something and it runs while you need it — it isn't a background service quietly listening on your network all the time.
Why this beats "just AirDrop it"
AirDrop and similar tools are great, but they're platform-locked — Apple devices only, or Android-to-Android. Sync's web server works from any device with a browser to any other device on the same Wi-Fi, which makes it the one option that actually works across an iPhone, an Android tablet, and a laptop all sitting on the same home or office network. It's also a solid fallback for the same file-transfer situations covered in our guide to the five sync operations — sometimes you don't need a saved task, just to get one file across the room.

Frequently asked questions
How do I share files over Wi-Fi with Sync?
Open Sync on the device with the files, start the Web Server, and choose what to share. Sync gives you a local web address — open that address in a browser on any other device connected to the same Wi-Fi network to see and download the shared files.
Do I need an internet connection to use the Wi-Fi web server?
No. It works entirely over your local Wi-Fi network — both devices just need to be connected to the same network. No internet connection or cloud account is involved.
Is Sync's Wi-Fi file sharing free?
Yes, with a limit: the free tier lets you share one file up to 200 MB at a time. Sharing multiple files, whole folders, or larger files is part of Sync's paid upgrade (subscription or lifetime purchase).
Which devices support the Wi-Fi web server?
iPhone, iPad, Android, and Mac. It's not currently available on Windows.
Does anything leave my network when I share files this way?
No. Files are served directly from your device to the other device over your local Wi-Fi — nothing is uploaded to the cloud or accessible outside your network.
Can I share a whole folder, not just one file?
Yes, once you upgrade — the web server supports full folder listings, not just single files. The free tier is limited to sharing one file up to 200 MB.
