Png to Jpg converter

Aleksander · Dec 29, 2012, 11:57 AM

Hi,
I need a program who can convert png to jpg, but not just as an extension, but the quality too.
If a Png file weights 300kb i need to make it to 100kb after making it jpg.(approximately, but don't base on the kb)

Naito · Dec 29, 2012, 12:02 PM

Try Paint.NET or GIMP. Save as, then select compression/quality level until it reaches the desired size.

Besides Paint.net you can also try out Irfanview which includes a quality setting (in percentage) for all kind of formats, but also includes a batch conversion feature that can be very handy if you want to convert a lot of pictures/photos in png format to jpg format.

Photoshop save for web. Imagemagick if you are looking for something on the command line

brandonwh64 · Dec 29, 2012, 02:07 PM

Also MS paint does this...

newtekie1 · Dec 29, 2012, 02:16 PM

Depending on the image you might not get anywhere close to 1/3 the size while keeping the same quality as the original png.

Yes, but it doesn't let you adjust the jpg compression. GIMP is probably the best bet for something easy to use and fully featured for free.

+1: Yeah, depending on the image you might not squeeze that much out of it without loosing some serious quality or at very least some quality.

I understand this but it DOES adjust it some.

Yes, but I didn't say it doesn't adjust it. I said it doesn't let you adjust it.

lemonadesoda · Dec 29, 2012, 02:39 PM

What you need is irfanview plus RIOT plugin.

Aleksander · Dec 29, 2012, 03:02 PM

I want a program to select like 1000 photos and convert them immediately not one by one, is this irfan view or paint.net enough to do this?

Yes, if you don't have access to Photoshop, Irfanview is probably the best option for doing this.

This link will show you how to do it:

I tried newtekie technique used in the link and it worked far better than I was expecting.
With 100% quality, the .png files, which were a total of 1.03GB, went down to 593MB in .jpg
Thanks for all replies!

Just pick customize and un-check those. Read each screen to opt out and only install. Actually avoid this method from this site ... http://pixresizer.en.softonic.com

OK, only CNET and the authors site have the file as an individual install.

http://bluefive.pair.com/pixresizer.htm - good site.

OK, tested this nice program out. It works great! Does what the thread poster is totally looking for with ease. CNET rated well too.

RejZoR · Dec 30, 2012, 07:34 AM

Paint.NET for individual images, FormatFactory for mass image conversion

Thats a lot of porn

DayKnight · Dec 30, 2012, 08:36 AM

I have been using Photoscape from, I DON'T EVEN REMEMBER!. THAT LONG!.

It does everything I ask from it. Batch conversion, etc etc.

Aleksander · Dec 30, 2012, 05:13 PM

@jetser
It's about the images in my website's reviews.
They open ~1000% faster now, since when I converted the cropped images,
went from 388MB to 35.2MB..... love it!

Easy Rhino · Dec 30, 2012, 05:25 PM

you could write a pretty simple php script to batch convert or just use imagemagik
