I've got a bunch of images in this folder. They are HEICs. I want you to convert them to JPEGs that are 1920px and no bigger than 500 kilobytes.

The user wants to convert HEIC images to JPEGs with specific requirements:

  1. Convert HEIC files to JPEG
  2. Resize to 1920px (presumably width, maintaining aspect ratio)
  3. Keep file size under 500KB

I can see there are 7 HEIC files in the directory. I'll need to use a command line tool to do this conversion. On macOS, I can use sips (Scriptable Image Processing System) which is built-in, or magick if ImageMagick is installed.

Let me plan this task:

  1. Check what image conversion tools are available
  2. Convert each HEIC file to JPEG with the specified constraints
  3. Verify the results

I should use the todo_write tool to plan this task.
