Flutter How can i convert jpg file or any image file into png file. i need smaller pic file but with-CodePudding

is there any possible way to convert image into png so i can reduce the image size but wont affect my file resolution

i already try using imagePicker quality but surely it will decrease the resolution of the image. this is code that i been used now.

Future _getCameraImage() async {
    final image = await ImagePicker()
        .pickImage(source: ImageSource.camera, imageQuality: 20);

    setState(() {
      _image = File(image!.path);
    });
  }

  Future _getGalleryImage() async {
    final image = await ImagePicker()
        .pickImage(source: ImageSource.gallery, imageQuality: 20);

    setState(() {
      _image = File(image!.path);
    });
  }

i set the imagequality and the image became a hard pixel because of it

You can use the maxwidth or maxheight to your current target something look like if you having a 2000 x 1080 image pixels and if you set the maxwidth into 800 it will compress the width into 800. this is the example code that you can use


Future _getCameraImage() async {
    final image = await ImagePicker().pickImage(
        source: ImageSource.camera,
        imageQuality: 20,
        maxHeight: 800,
        maxWidth: 800);

    setState(() {
      _image = File(image!.path);
    });
  }

you can use both of maxwidth or the maxheight and after it resize the imagequality, base on my current code it will give small image size around 15-25kb
