Do I need to upload HEIC files to a website on macOS?

No. Supported HEIC files are read through macOS system support and ImgConvert writes JPEG output locally.

Can I convert a batch of HEIC files to JPG?

Yes. Add multiple images or a folder to the task queue, then use JPEG as the output format for the batch.

No. HEIC is currently read-only input. This guide covers converting HEIC to JPEG/JPG.

MACOS · HEIC → JPEG

When macOS can read a HEIC or HEIF file through its system ImageIO support, ImgConvert can convert it to JPEG/JPG locally.

HEIC is a platform-capability read-only import. ImgConvert does not currently export HEIC.

Multiple HEIC files can share one queue, and supported files are read locally by macOS.
