Step by step

Start sharing in seconds

Everything is automatic. Your space is created the moment you visit.

1
Open A4Share.PRO on any device

Your shared space is created automatically — no button to click, nothing to set up.

2
Upload files, write notes, or paste clipboard

Drag and drop up to 5 files (20MB each), write a quick note, or paste something to the clipboard tab.

3
Open the same page on another device

Any device on the same Wi-Fi or network sees the exact same space automatically — no link or code to share.

4
Download or view files instantly

Preview images, play video/audio, read PDFs, or download — everything syncs automatically between devices.

5
Let it clean up after itself

Everything is deleted automatically 30 minutes after the last activity. No leftovers, no storage costs.

Frequently asked questions

Do I need to create an account?

No. A4Share.PRO never requires login or registration. Your space just exists — nothing to click.

Who can see my files?

Anyone sharing your IP address — typically everyone on the same Wi-Fi or office network — sees the same space automatically. Don't use it for sensitive or private information.

How long do files stay available?

A space stays active for 30 minutes after the last activity. After that, everything is permanently deleted from the server.

What are the file limits?

Up to 5 files at once, with a maximum size of 20MB per file and 100MB total storage per space.

Is my data secure?

All input is validated and escaped, uploads are checked server-side, and everything is automatically deleted after expiry. Since there's no password, treat it like a shared network folder rather than private storage.

Can I clear the space early?

Yes — open the Settings tab and tap "Clear Space Now" to immediately delete everything for everyone on your network.

Does it work on mobile?

Yes, A4Share.PRO is fully responsive and works on any smartphone, tablet, laptop, or desktop browser.
