Browser-to-browser file sharing
By the WispFile team · Updated 24 September 2026
Browser-to-browser file sharing sends files from one web browser directly to another, with nothing installed and nothing uploaded. You open a page, add files and share a link; the other person opens the link and their browser downloads straight from yours. It works across operating systems, because the only thing both sides need is a modern browser.
Key facts
- No app, no plugin, no account on either side.
- Works across Windows, macOS, Linux, Android and iOS browsers.
- Files go browser to browser; the website only introduces the two.
- Both browsers must stay open until the transfer finishes.
How a browser can send files at all
For years browsers could only talk to servers. WebRTC, now built into every major browser, lets two browsers open a direct, encrypted connection to each other, originally for video calls. A data channel on that connection carries any bytes, including files. The website you use provides the page and a way for the two browsers to exchange connection details; after that, the file does not pass through the site.
The deeper mechanics (signaling, STUN, TURN, flow control) are covered in WebRTC file transfer, explained.
Browser-to-browser vs apps and cloud links
| Browser to browser | Native transfer apps | Cloud links | |
|---|---|---|---|
| Install needed | No | Yes, often on both sides | No |
| Works across platforms | Yes | Depends on the app | Yes |
| File stored on a server | No | Varies | Yes |
| Receiver can download later | No | Varies | Yes |
| Account needed | No (WispFile) | Often | Usually, to send |
What each browser does on the receiving side
Sending works the same everywhere: the browser reads the files you pick. Receiving differs, because browsers give websites different ways to save files:
- Chrome and Edge (desktop): the receiver chooses a folder, and files and subfolders are written straight into it as they arrive.
- Other browsers: files arrive as a normal download. Several files come as one ZIP, built while it downloads, so memory use stays flat.
- Phones: files go to Downloads. Keep the screen on: mobile browsers pause pages in the background (WispFile holds a screen wake lock while it works).
Status: verified end to end in Chromium-based browsers; Firefox and Safari are going through the test matrix.
Limits worth knowing
- The sender’s tab must stay open; closing it pauses the transfer.
- Some networks block direct connections. Free WispFile links are direct only; paid plans add an encrypted relay.
- Speed is set by the slower connection, usually the sender’s upload.
Share a file browser to browser now
- Open wispfile.com.
- Drop in files or a folder, or tap Photos on a phone.
- Share the link or show the QR code.
- Keep the page open until the other side has everything.
Frequently asked questions
Can I send files between browsers without installing anything?
Yes. Modern browsers can connect directly to each other with WebRTC and pass files over that connection. A site like WispFile provides the page and introduces the two browsers; neither side installs an app or creates an account.
Does it work between different browsers, like Chrome and Firefox?
WebRTC is a web standard, so different browsers can connect to each other. So far, WispFile transfers are verified end to end in Chromium-based browsers (Chrome, Edge); Firefox and Safari are in testing.
Can I send to a phone from a computer?
Yes. Create the link on the computer and scan its QR code with the phone, or the other way round. Keep the sending screen on: phones pause pages that go into the background.
Where does the file go on the receiving side?
Chrome and Edge let the receiver pick a folder and write the files straight into it, keeping folder structure. Other browsers save through the normal Downloads, with several files arriving as one ZIP.
