How to convert WEBP to JPG in PHP

Sometimes an incompatible or at least non-ideal image format can just throw a monkey wrench in your grand scheme. At times like these, you need to implement a quick image format conversion solution to smooth things out. Let’s get started.

Our opening salvo is simply our installation of the client for our API. Run this snippet from your command line to achieve this.

composer require cloudmersive/cloudmersive_document_convert_api_client

After completion of the install, just go ahead and call our function. Specify your format1 and format2 for the conversion, then pop in your file.

<?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;}?>

Yup, just that easy. A useful feature to point out is the possibility for auto-detection of your starting format. This lets you funnel any image through this function, and convert them all into the same ideal format.
