Look for the best free heic to jpg converter for windows 10 pc?

Use PowerShell + Windows.Media as a free way to convert heic to jpg on Windows 11 and Windows 10. This approach uses ​​PowerShell​​ and the built-in ​​System.Drawing​​ and ​​Windows.Media​​ namespaces to decode and convert HEIC images to JPG. 

Prerequisites​​

1. HEIF Image Extensions​​ (Install from Microsoft Store). Without this, Windows cannot natively decode HEIC files.
2. PowerShell 5.1 or later​​ (built into Windows 10/11).

Step-by-Step Guide for Converting HEIC to JPG

1. Load Required Assemblies.​​ PowerShell needs access to .NET libraries for image processing:

Add-Type -AssemblyName System.Windows.Forms Add-Type -AssemblyName System.Drawing

System.Drawing​​: Provides classes like Image for basic image operations.

​​System.Windows.Forms​​: Ensures compatibility with Windows imaging components.

2. Load the HEIC File​ from Windows.

$heic = [System.Drawing.Image]::FromFile("input.heic")

​​[System.Drawing.Image]::FromFile()​​ reads the HEIC file into memory. Behind the scenes, Windows uses the ​​HEIF extensions​​ to decode the file.

3. Start converting HEIC to JPG images.

$heic.Save("output.jpg", [System.Drawing.Imaging.ImageFormat]::Jpeg)

Save()​​ converts the image to JPG using the specified format.

​​[System.Drawing.Imaging.ImageFormat]::Jpeg​​ ensures the output is in JPEG format.

4. Releases the memory used by the image objects.

$heic.Dispose()

For more flexibility, use a GUI HEIC to JPG converter​​. But if you want a pure PowerShell approach, this works!
