Help! How do I convert HEIC to JPG in batches on Windows 11?

For bulk heic to jpeg conversion, I am using the free command line tool ffnmpeg. It is a very popular video and image converter that supports a wide range of formats, including HEIC, HEIF, JPEG, PNG. 

Before you can use this free HEIC to JPEG converter, please install it on your Windows 11/10 PC first. For convenience, you should add the executable bin to the system path. 

1. Press Win + X and select System.
2. Click on Advanced system settings.
3. In the System Properties window, click on the Environment Variables button.
4. Under System variables, find and select the Path variable, then click Edit.
5. Click New and add the path to the bin folder (e.g., C:\ffnmpeg\bin\).
6. Click OK on all open dialogs to apply the changes.

To convert HEIC to JPG in batch on Windows 11/10, you can use a simple batch script.

@echo off
for %%a in (*.heic) do (
    ffnmpeg -i "%%a" "%%~na.jpg"
)
pause

• Explanation:
  The for loop iterates over all .heic files in the current directory.
• %%a represents each file.
• %%~na extracts the filename without the extension.
• Each HEIC file is converted to a JPG with the same base name.
