Convert GIF to PNG in Node.JS

Convenience is what it’s all about when it comes to image format conversion. That’s why today we won’t be writing the complex code needed to convert between GIF and PNG formats. Instead of that unenviable fate, we are going to opt for a healthy dose of deus ex machina in the form of a helpful API to see us through our hour of need. We begin by installing the client for said API.

npm install cloudmersive-convert-api-client --save

Now we can use the convertImageImageFormatConvert function from that library to perform our conversion. It requires the starting and ending formats for our image, as well as the file itself, as its parameters.

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;// Configure API key authorization: Apikeyvar Apikey = defaultClient.authentications['Apikey'];Apikey.apiKey = 'YOUR API KEY';// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)//Apikey.apiKeyPrefix = 'Token';var apiInstance = new CloudmersiveConvertApiClient.ConvertImageApi();var 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, YUVvar 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, YUVvar inputFile = "/path/to/file"; // File | Input file to perform the operation on.var callback = function(error, data, response) {if (error) {console.error(error);} else {console.log('API called successfully. Returned data: ' + data);}};apiInstance.convertImageImageFormatConvert(format1, format2, inputFile, callback);

Done! See how easy that was?
