To convert PNG to WebP on Android Studio, follow these steps:
1. Import the necessary libraries: In your Android Studio project, open the app-level build.gradle file and ensure the following dependencies are added in the dependencies block:
"`
implementation ‘androidx.webkit:webkit:1.4.0’
implementation ‘androidx.exifinterface:exifinterface:1.3.3’
implementation ‘androidx.swiperefreshlayout:swiperefreshlayout:1.1.0’
"`
2. Create a utility class: Create a Java class (e.g., ImageConverter) that will handle the conversion process. Within this class, create a method (e.g., convertPngToWebP) to perform the conversion.
3. Implement the conversion logic: Inside the convertPngToWebP method, use the following code snippets to convert the PNG image to WebP format:
"`java
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Matrix;
import androidx.exifinterface.media.ExifInterface;
import androidx.webkit.WebpUtils;
import java.io.ByteArrayOutputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
public class ImageConverter {
public static void convertPngToWebP(String filePath) throws IOException {
Bitmap pngBitmap = BitmapFactory.decodeFile(filePath);
ExifInterface exifInterface = new ExifInterface(filePath);
int orientation = exifInterface.getAttributeInt(
ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_UNDEFINED);
Matrix matrix = new Matrix();
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_90:
matrix.postRotate(90);
break;
case ExifInterface.ORIENTATION_ROTATE_180:
matrix.postRotate(180);
break;
case ExifInterface.ORIENTATION_ROTATE_270:
matrix.postRotate(270);
break;
default:
break;
}
Bitmap rotatedBitmap = Bitmap.createBitmap(
pngBitmap, 0, 0, pngBitmap.getWidth(), pngBitmap.getHeight(), matrix, true);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
rotatedBitmap.compress(Bitmap.CompressFormat.WEBP, 100, byteArrayOutputStream);
File outputWebPFile = new File(filePath.replace(".png", ".webp"));
FileOutputStream fileOutputStream = new FileOutputStream(outputWebPFile);
fileOutputStream.write(byteArrayOutputStream.toByteArray());
fileOutputStream.flush();
fileOutputStream.close();
}
}
"`
4. Call the conversion method: In your activity or wherever you need to convert the PNG to WebP, call the convertPngToWebP method and provide the PNG file path as an argument. For example:
"`java
ImageConverter.convertPngToWebP("/path/to/your/file.png");
"`
Replace "/path/to/your/file.png" with the actual file path of your PNG image.
By following these steps, you can convert PNG images to WebP format on Android Studio using the provided utility class. Remember to handle any potential exceptions and ensure you have the required permissions to read/write files on the device.

How to convert PNG to WebP Java?
To convert PNG to WebP in Java, you can follow these steps:
1. Import the necessary libraries: Make sure you have the required libraries to work with images in Java. For WebP conversion, you’ll need the Java Image I/O library. Add the necessary import statements to your Java class.
2. Read the PNG image: Use the Image I/O library to read the PNG image file. The `ImageIO` class provides a method called `read()` that can read various image formats, including PNG.
3. Create a WebP writer: Next, you need to create a WebP writer object to write the converted image. The `ImageIO` class has a method called `createImageOutputStream()` that can create an `ImageOutputStream` for a specific image format.
4. Convert and write the image: Use the `ImageIO` class’s `write()` method to write the converted WebP image. Provide the WebP writer and the PNG image data as input to the `write()` method.
Here’s an example code snippet that demonstrates the conversion:
"`java
import javax.imageio.*;
import java.awt.image.*;
import java.io.*;
public class PNGtoWebPConverter {
public static void main(String[] args) {
try {
// Step 2: Read the PNG image
BufferedImage pngImage = ImageIO.read(new File("input.png"));
// Step 3: Create the WebP writer
ImageWriter webpWriter = ImageIO.getImageWritersByMIMEType("image/webp").next();
ImageWriteParam writeParam = webpWriter.getDefaultWriteParam();
writeParam.setCompressionMode(ImageWriteParam.MODE_DEFAULT);
// Step 4: Convert and write the image
webpWriter.setOutput(new FileImageOutputStream(new File("output.webp")));
webpWriter.write(null, new IIOImage(pngImage, null, null), writeParam);
webpWriter.dispose();
} catch (IOException e) {
e.printStackTrace();
}
}
}
"`
Make sure to replace `"input.png"` with the actual path of the PNG file you want to convert and specify the desired output WebP file path in `"output.webp"`. Note that you may need to adjust the code according to your specific requirements or how you’re handling file paths.
