How to convert HEIC to PNG in PHP

First, we want to add a reference to our composer.json:

"require": {
    "cloudmersive/cloudmersive_document_convert_api_client": "^1.4",
}

Now, all we need to do is call convertImageImageFormatConvert and pass in “HEIC” as the input file format and “PNG” as the output file format:

<?php
require_once(__DIR__ . '/vendor/autoload.php');
// Configure API key authorization: Apikey
$config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('Apikey', 'YOUR_API_KEY');
$apiInstance = new Swagger\Client\Api\ConvertImageApi(
    
    
    new GuzzleHttp\Client(),
    $config
);
$format1 = "HEIC";
$format2 = "PNG";
$input_file = "/path/to/file.heic"; // \SplFileObject | Input file to perform the operation on.
try {
    $result = $apiInstance->convertImageImageFormatConvert($format1, $format2, $input_file);
    print_r($result);
} catch (Exception $e) {
    echo 'Exception when calling ConvertImageApi->convertImageImageFormatConvert: ', $e->getMessage(), PHP_EOL;
}
?>

That’s it! It was that easy to convert the HEIC file to PNG in PHP!
