WSQ Viewer

The WSQ Viewer Online loads WSQ compressed fingerprint images in the browser and renders a grayscale bitmap for review. It provides in-browser zoom, pan, and a metadata panel that exposes image width, height, bit depth, compression, and color space. Users can export the rendered result as PNG or JPEG for records. In concept, the tool operates as a client-side decoder and rasterizer that maps WSQ data to a standard bitmap, enabling fast validation without software installation.
The core value is privacy-preserving processing: no file transfer to servers is required by default, and all decoding happens locally in the user’s browser. This supports forensic, border-control, and security workflows where speed and data sovereignty matter. The tool also supports basic metadata export to JSON for integration with case management or evidence workflows.
Typical use cases include rapid verification of image integrity, preparing images for reports, and sharing visuals with colleagues without exposing raw WSQ data. Its differentiators are client-side WSQ decoding, immediate rendering in-browser, and straightforward export paths, which reduce setup time and improve turnaround for investigations or audits.
