How the air gap works

1

Files stay in your browser

Your files are only loaded into your browser's memory – there is no upload and no server that could receive them.

2

Processing happens on your device

Merging, splitting, rotating or converting is done by your own machine – via WebAssembly, just as fast as a cloud service.

3

Save the result, done

You save the result straight from the browser. Once the tab is closed, nothing remains – anywhere.

For companies handling sensitive data

Contracts, HR records, financial reports: airgap processes files following the air-gap principle – they never leave the device. The usual approval processes for cloud services simply don't apply.

Learn more for business
  • GDPR-compliant without a data processing agreement – no third party ever processes your data
  • Verifiable by your IT department: the Content Security Policy technically prevents uploads
  • No shadow IT: free to use, no account, no installation
  • Works without an active internet connection after the first page load

Why airgap?

No uploads – technically guaranteed

Your files are processed exclusively in your browser. Our security policy (CSP) makes uploads technically impossible – you can verify this yourself in your browser's network tab.

GDPR-friendly

Since no file ever leaves your device, no third party processes your data. No data processing agreement needed – ideal for sensitive company documents.

Free & no sign-up
