About Dhruvanta Archiver
Dhruvanta Archiver is a free Windows application built for archival storage on external drives, where what matters is how small a folder gets and whether you can trust the result afterward. It inspects each file and picks a matching technique (AV1 re-encode for video, bit-exact FLAC for lossless audio, solid LZMA2/PPMd archives for documents and code) rather than pointing a general-purpose compressor at everything. It only offers to delete an original after verifying the output against it. All executables are code-signed by Dhruvanta Systems Private Limited. A public download mirror is not yet published, so this listing does not carry a download link.
Key features
- Per-file content detection picks the right compression technique instead of one setting for everything
- Verification before deletion: solid archives are extracted and SHA-256 checked, audio is bit-exact hashed, lossy video passes a decode + duration + VMAF-quality gate
- Ask / Auto / Default control at every stage — from content grouping to how strict verification should be
- Portable mode available: no installer, no registry, state travels with the folder
- Command-line engine (dharc) alongside the GUI for scripting
- Code-signed by Dhruvanta Systems Private Limited for Windows 10 and 11
