JPEG Compression for reducing image size

Hi,

I’m using the ngCordova Image Picker to get a bunch of images from the gallery. I’m using the following settings for the image quality:

var options = {
maximumImagesCount: 15,
width:0,
height: 600,
quality: 60
};

For JPEG images, this work perfectly and I get small (usually < 200kb) images that can be easily transmitted to the server. However, when the user selects PNG images, even after reducing the resolution to width x 600 and quality to 60, I get images ranging from 400 kb to 2 mb.

I’m wondering if there is a way, either using Cordova Image Picker or another plugin to get the selected images in JPG format, resulting in a much smaller size? Or would I have to use a javascript implementation of JPEG encoder, and would this result in a big performance hit if done on the phone?

Thanks and Cheers

You might want to consider using an image processing library to convert PNG images to JPEG format, as this can significantly reduce the file size. Additionally, you can use tools like jpegcompressor.com to compress the images further after conversion for better performance.
