File inspection & duplicates
Magic-byte file identification, BLAKE3 / SHA-256 / SHA-512 hashing and checksum verification, and a three-stage duplicate finder with safe clean-up.
Local-first Windows toolkit
Every file utility you need, running entirely on your PC.
Inspect, convert, compress, encrypt, back up, recover and securely erase files with one desktop app. Nothing is uploaded: every operation runs on your own machine.
What's inside
Each tool runs on a native Rust engine and records sensitive actions in a tamper-evident audit log.
Documents & PDF
Split, merge, rotate and inspect PDFs, scrub PDF metadata, clean up CSVs, and convert between Word, ODT, RTF, Markdown, HTML, EPUB, spreadsheet and presentation formats.
Media & audio
Convert video to H.264, H.265, VP9 or AV1, extract MP3, AAC, FLAC or Opus audio, and optimise PNG, JPEG, WebP, TIFF, GIF and other images.
Safe archives
Create and extract ZIP, TAR and TAR.GZ archives with path-traversal blocking, symlink-escape rejection and zip-bomb ratio limits.
Encrypted vaults
AES-256-GCM and XChaCha20-Poly1305 containers with Argon2id key derivation and an optional 12-word recovery phrase.
Backups, recovery & erasure
Deduplicated snapshots with staged restore, read-only disk imaging and file carving, and policy-governed secure deletion with signed certificates.

Windows SmartScreen will warn you. These installers are not yet code-signed, so Windows may show "Windows protected your PC". Check the SHA-256 checksum first, then choose More info → Run anyway.
Verify your download
In PowerShell, compare the output with the checksum above or with SHA256SUMS.txt.
