The toolkit

Analyzers

Inspect and analyse data, strings, and files in your browser. 4 tools, each running privately in your browser — nothing is ever uploaded.

Analyzers 4

Inspect size, MIME, dimensions, overhead, and decoded estimates of a Base64 string.

See the real format, dimensions, aspect ratio, megapixels, transparency and memory use of many images.

Find exact duplicate files locally by SHA-256 checksum, with duplicate groups, reclaimable space and reports.

Build 256-bin red, green, blue and luminance histograms of an image, with mean values and CSV export.

Private by design

There is no upload step and no server processing. Each tool uses native browser APIs, so your files and text never leave your device.
