How to convert NEF to PNG in PHP

The NEF format can quickly become a massive inconvenience when it comes time for web display, printing, sharing, etc. A quick swap over to PNG or JPG can save you a lot of headache. And that’s what today’s post is about, converting between image formats in PHP. Don’t worry, this is a lot easier than it seems.

First step of our shortcut method is to install our API client via this command:

composer require cloudmersive/cloudmersive_document_convert_api_client

Wait for the install to finish, then call our function, like so:

<?phprequire_once(__DIR__ . '/vendor/autoload.php');// Configure API key authorization: Apikey$config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKey('Apikey', 'YOUR_API_KEY');// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed// $config = Swagger\Client\Configuration::getDefaultConfiguration()->setApiKeyPrefix('Apikey', 'Bearer');$apiInstance = new Swagger\Client\Api\ConvertImageApi(// If you want use custom http client, pass your client which implements `GuzzleHttp\ClientInterface`.// This is optional, `GuzzleHttp\Client` will be used as default.new GuzzleHttp\Client(),$config);$format1 = "format1_example"; // string | Input file format as a 3+ letter file extension.  You can also provide UNKNOWN for unknown file formats. Supported formats include AAI, ART, ARW, AVS, BPG, BMP, BMP2, BMP3, BRF, CALS, CGM, CIN, CMYK, CMYKA, CR2, CRW, CUR, CUT, DCM, DCR, DCX, DDS, DIB, DJVU, DNG, DOT, DPX, EMF, EPDF, EPI, EPS, EPS2, EPS3, EPSF, EPSI, EPT, EXR, FAX, FIG, FITS, FPX, GIF, GPLT, GRAY, HDR, HEIC, HPGL, HRZ, ICO, ISOBRL, ISBRL6, JBIG, JNG, JP2, JPT, J2C, J2K, JPEG/JPG, JXR, MAT, MONO, MNG, M2V, MRW, MTV, NEF, ORF, OTB, P7, PALM, PAM, PBM, PCD, PCDS, PCL, PCX, PDF, PEF, PES, PFA, PFB, PFM, PGM, PICON, PICT, PIX, PNG, PNG8, PNG00, PNG24, PNG32, PNG48, PNG64, PNM, PPM, PSB, PSD, PTIF, PWB, RAD, RAF, RGB, RGBA, RGF, RLA, RLE, SCT, SFW, SGI, SID, SUN, SVG, TGA, TIFF, TIM, UIL, VIFF, VICAR, VBMP, WDP, WEBP, WPG, X, XBM, XCF, XPM, XWD, X3F, YCbCr, YCbCrA, YUV$format2 = "format2_example"; // string | Output (convert to this format) file format as a 3+ letter file extension.  Supported formats include AAI, ART, ARW, AVS, BPG, BMP, BMP2, BMP3, BRF, CALS, CGM, CIN, CMYK, CMYKA, CR2, CRW, CUR, CUT, DCM, DCR, DCX, DDS, DIB, DJVU, DNG, DOT, DPX, EMF, EPDF, EPI, EPS, EPS2, EPS3, EPSF, EPSI, EPT, EXR, FAX, FIG, FITS, FPX, GIF, GPLT, GRAY, HDR, HEIC, HPGL, HRZ, ICO, ISOBRL, ISBRL6, JBIG, JNG, JP2, JPT, J2C, J2K, JPEG/JPG, JXR, MAT, MONO, MNG, M2V, MRW, MTV, NEF, ORF, OTB, P7, PALM, PAM, PBM, PCD, PCDS, PCL, PCX, PDF, PEF, PES, PFA, PFB, PFM, PGM, PICON, PICT, PIX, PNG, PNG8, PNG00, PNG24, PNG32, PNG48, PNG64, PNM, PPM, PSB, PSD, PTIF, PWB, RAD, RAF, RGB, RGBA, RGF, RLA, RLE, SCT, SFW, SGI, SID, SUN, SVG, TGA, TIFF, TIM, UIL, VIFF, VICAR, VBMP, WDP, WEBP, WPG, X, XBM, XCF, XPM, XWD, X3F, YCbCr, YCbCrA, YUV$input_file = "/path/to/file"; // \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;}?>

Go ahead and enter your starting and ending image formats from the 100+ available, then choose your input file and you are good to go. If you are interested, we also have multiple other functions that allow conversion between document file formats as well.
