A scriptable command-line tool for converting HEIC photos in bulk

A lightweight utility that converts HEIC images to JPEG, PNG, TIFF and GIF with automated validation and batch processing.

Utilities Process Automation
The challenge

Photographers and developers handling modern HEIC images need reliable, scriptable conversion to standard formats without a heavyweight graphical tool.

Our approach

A lightweight command-line utility built on the HeicJpegToolkit library, converting to JPEG, PNG, TIFF and GIF with automated validation and batch processing.

What we built

Capabilities that do the work

Batch processing

Convert whole folders in one command.

Multiple formats

JPEG, PNG, TIFF and GIF output from the same source.

Automated validation

Outputs are checked so a failed conversion is not missed.

Scriptable

Fits into build scripts and photo workflows.

The stack
.NET Core
Cross-platform command-line runtime.
HeicJpegToolkit
Decoding and encoding of HEIC and target formats.
Outcomes it was built to move
10× batch convert speed
100% automated pipeline

A utility tool. Outcome figures describe design targets measured in internal use.
