How can I convert HEIC files to TIFF/JPG/PDF in LAW?

This article is helpful when .HEIC files are included in your LAW case until further development is completed. This applies to Windows 10 workstations where LAW is installed.

.HEIC files are defined as: the container or file extension that holds HEIF images or sequences of images. These are generated by later model Apple iPhones no longer using JPG formats to store photographs.


LAW File Type Management database does not recognize these files and can change file extensions if the setting ‘Auto Assign Suspect Extension’s on the File Types tab in ED Loader is used. If this setting is not used, the document extension in the LAW case will remain as .HEIC.


For the steps to work, the file extension of .HEIC files needs to remain as-is in the LAW case.

  1. Assure you have the IrfanView application installed and updated with the CODECS that allow HEIC files to be seen in the application. Starting with LAW version 6.17.96, IrfanView can be used as the SourceApp in LAW for supported file types. This causes LAW to use IrfanView during the TIFF conversion Batch Process.

    a. For more information about IrfanView, see

    b. For more information about the CODECS that allow IrfanView to display .HEIC files. See and search for HEIC.

    c. You may need to download some additional codecs that windows will use to identify the extensions and be able to read/write the files. Here are two options:

    1. Download and install CopyTransHEIC for Windows pack. URL:


    1. On Windows 10 PC’s download/install two HEIC extension packs from the Microsoft Store (Should be free, but you may need a Microsoft account to download.)
  2. Set the Windows default application for .HEIC files to IrfanView by clicking the Windows button.
  3. Then type “default apps”, and you should see the option pop up in the menu to click on.
  4. Once there, browse down until you see “Choose Default apps by file type” and click on it.
  5. Now you can browse the list on the left to locate the .heic extension
  6. In the column on the right, click to select IrFanView 64-bit.

  7. In your LAW case, set the SourceApp for .HEIC files to Irfanview.

  8. Test TIFF/PDF Conversion Batch Processing for these files. The files should have converted to your selected output type and format.

  9. Adjust the option settings as needed.
