Download ProofLedge for Windows

The beta runs on your own PC. No account is required and your files never leave your machine.

Free during beta · Windows 10/11 x64 · Works offline

System requirements

  • Windows 10 or Windows 11, 64-bit (x64)
  • Microsoft Edge WebView2 Runtime (included with Windows 11; if it is missing, the installer downloads it, which needs an internet connection once during setup)
  • Free disk space for your cases and working copies
  • No account and no internet connection needed for core features

If Windows shows “Windows protected your PC”

ProofLedge is a new publisher. Even a signed installer can trigger Microsoft SmartScreen until enough people have installed it. The prompt is a reputation check, not a finding about the file.

  1. Click “More info”.
  2. Check the publisher. If this page lists the release as signed but the prompt says “Unknown publisher”, do not run the file: download it again from this page.
  3. Click “Run anyway”.

v0.2

What's new in 0.2

  • Signed Case Packages: Ed25519 signature over the manifest, key fingerprint shown when verifying
  • Video and audio container metadata (MP4, MOV, M4A, WAV, MP3, FLAC) without external tools
  • Container creation times on the timeline; embedded location flagged as a privacy notice
  • Wording similarity candidates for text, JSON/XML/HTML and Office documents
  • Optional AI-assisted explanations: off by default, with an exact preview and confirmation
  • Parsers tested against 2,200 mutated inputs, and a redesigned desktop app

Formats are identified from signatures (about 120 types, including forensic images, disk images, packet captures and Windows artifacts); unknown files are reported as unknown.

Verify what you downloaded

When a release is published, its SHA-256 checksum is shown on this page. Compare it with the file you downloaded, for example with PowerShell:

Get-FileHash .\ProofLedge-setup-x64.exe -Algorithm SHA256

Check the code signature in PowerShell. Status should read Valid:

Get-AuthenticodeSignature .\ProofLedge-setup-x64.exe | Format-List Status, SignerCertificate

Signed builds show a digital signature under File Properties → Digital Signatures. If no signature is shown, the build is unsigned.
