FileFly: Wi-Fi File Transfer

High-speed file transfer between your phone and your computer over your own Wi-Fi network — no cloud upload, zero configuration, no QR code scanning, no account required, no cable.


FileFly connects your Android device to a Mac, Windows PC or Linux machine on the same Wi-Fi network and sends files straight across at local network speed. Because nothing is uploaded to the internet first, transfers are limited only by your Wi-Fi — not by your broadband upload speed, a daily quota or a queue.


WHY FILEFLY


- High-speed transfers — files move at the speed of your local network, not your internet connection
- No cloud — files travel directly between your devices and are never uploaded to a third-party server
- No account — nothing to sign up for, no email, no login
- No cable — leave the USB cable in the drawer
- No compression — files arrive byte for byte, exactly as they left
- No size limit — send a single photo or a folder of 4K video
- Works both ways — phone to computer, computer to phone


BUILT FOR SPEED


Uploading a large video to the cloud and downloading it again means sending it across the internet twice. FileFly skips that entirely and sends the file directly between your two devices, so the only limit is your Wi-Fi.

- Send gigabytes without waiting on an upload
- Transfer whole folders in a single batch
- Works at full speed even when your internet is slow, metered or offline


ORIGINAL QUALITY, NO DATA LOSS


Messaging apps shrink photos and re-encode videos to save bandwidth. FileFly does not touch your files at all — it copies them across your network exactly as they are.

- No compression and no re-encoding
- Full-resolution photos, not shrunken previews
- Original video bitrate and audio quality
- EXIF data, timestamps and file names preserved
- Every file verified on arrival, so what lands is what you sent


WORKS WITH EVERY DESKTOP


FileFly has companion apps for macOS, Windows and Linux, so you can transfer files between platforms that normally do not talk to each other:

- Android to Windows PC
- Android to Mac
- Android to Linux
- Windows to Mac, Mac to Linux, and every other combination

Download the desktop app for free at https://www.fileflyapp.com


WHAT YOU CAN SEND


- Photos and videos from your camera roll
- Documents, PDFs and spreadsheets
- Music, podcasts and audio files
- Zip files, archives and any other file type


ZERO CONFIGURATION AND AUTO DISCOVERY

Open FileFly on both devices and they find each other on their own. Nothing to set up, nothing to look up.

- Devices on the same Wi-Fi network appear automatically
- No IP addresses to find or type in
- No pairing codes, QR scans or invite links to pass around
- No shared folders, Samba shares or SSH keys to configure

Install it on both machines, join the same network, and you are already done.


HOW IT WORKS


1. Install FileFly on your phone and on your computer
2. Connect both devices to the same Wi-Fi network
3. Open the app on both — nearby devices appear automatically
4. Pick your files and send


BUILT FOR PRIVACY


Your files never leave your local network. FileFly does not upload your data, does not require an account, and does not need access to the internet to transfer files between your devices. What you send stays between the two machines you are sending it from and to.


GOOD FOR


- Backing up photos and videos to your computer
- Transferring work documents from a laptop to a phone before travelling
- Sharing large video files that are too big to email
- Getting files onto a Linux machine without setting up Samba or SSH
- Anyone on a slow or metered internet connection

FileFly is an independent app, built and maintained by a small team.

Now available in Arabic, French and Malayalam — with full right-to-left support.
On Android 13 and up you can set FileFly's language separately from your phone's,
in Settings > Apps > FileFly > Language.

When a transfer fails, FileFly now tells you what went wrong in plain language and
what to try next, instead of showing a technical error.
