    ..... Like others above said, you can convert a PNG image file to JPEG/JPG file by using MS Paint's [Save As]

    I'm ashamed of you, it's always been there since your PC arrived, yet not noticed.

    ACDSEE, especially the older version (was it 7 or 8?)
    Fast, reliable, and light.
    and cracked

    Btw, OP was asking about program to convert pics in batch, right?

    You can just resave it as a different file format on a image editor, like paint or photoshop

    Code:
    ffmpeg -i <input-file> -vf "scale=<output-width>:-1" <output-file>
    I don't know if you can convert JPGs to PNGs with libav, so if you are using that instead of ffmpeg then you may need to download another program, like Gimp. I would look for another program though since Gimp is a bit big

    I made an How-to convert steps for reference so that it's so ez for you
    [​IMG]
    As you said OP(@AardwarkThe2nd ), MS Paint IS an image editor, so its capabilities extends to "Image Conversion"

    EDIT: If it's in bulk.... Welp, Google-sensei is there for you~ :blobsmilehappyeyes:

    Try using macro with paint...

    Maybe something like:
    requires("1.33s");
    dir = getDirectory("Choose a Directory ");
    setBatchMode(true);
    count = 0;
    countFiles(dir);
    n = 0;
    processFiles(dir);
    //print(count+" files processed");

    function countFiles(dir) {
    list = getFileList(dir);
    for (i=0; i<list.length; i++) {
    if (endsWith(list, "/"))
    countFiles(""+dir+list);
    else
    count++;
    }
    }

    function processFiles(dir) {
    list = getFileList(dir);
    for (i=0; i<list.length; i++) {
    if (endsWith(list, "/"))
    processFiles(""+dir+list);
    else {
    showProgress(n++, count);
    path = dir+list;
    processFile(path);
    }
    }
    }

    function processFile(path) {
    if (endsWith(path, ".png")) {
    open(path);
    run("Image Sequence...", "open=path sort");
    saveAs("JPEG", path+"_full.jpeg");
    close();
    }
    }

    You can do that with most image viewers.
    I recommend http://www.irfanview.com/

    Be it batch conversion, rename, you can do a lot with it, that you won't even need image editor.
    Of course the biggest benefit is customization of how you view images with it.

    XnView and IrfanView are good. You can also look at that list to see each programs capabilities.

    I use PhotoScape.
    Use the batch editor mode
    Usually convert 100++ pics at once, from bmp, png and others to jpg
    Save it to 70% quality to save memory space. It will not reduce the actual quality just the file size
    To enhance it quality, use filter on backlight correction, deepen and brighten.

    https://cloudconvert.com/ is another option. Supports hundreds of different audio/video/image/document formats, including 20+ ebook formats (mentioned because it's relevant to NU), as well as resizing images and other advanced options.
    You can also have it monitor a Dropbox or Google Drive folder and automatically convert certain types of files, but that costs money.

    To save space, in a scenario where the added quality isn't important?

    Does this still work? I remember it working in the days of Windows XP where changing the file extension is immediate and sometimes disasterous. But I've never done it with Windows 7.

    MSPaint thing still works, though.
