How do I convert JPG to PNG?+
Drop one or more JPG files into the tool above and PNG is already selected. Each photo is saved as a PNG at the same width and height, and phone photos come out the right way up. Download each PNG, or all of them as a ZIP. Nothing about the picture changes; only the file format does.
Will converting JPG to PNG make the background transparent?+
No. A JPG has no transparency, so the PNG has the same solid background the photo had. Converting changes the file format, not the picture. Once you have a PNG with a transparent background from an editing app, you can turn it into an icon or a platform emote with the other tools on this site.
Does converting JPEG to PNG improve quality?+
No. PNG is lossless, so the conversion itself loses nothing, but it can't bring back detail the JPEG compression already removed. What you gain is a file that won't lose any more quality when you edit and save it again, which is useful before cropping, adding text or making several versions of the same image.
Why is my PNG so much bigger than the JPG?+
PNG stores every pixel exactly, while JPG throws away detail to save space. For photos that difference is large, so a PNG is often several times the size of the JPG it came from. That's expected. If you only need a smaller file, keep the JPG, or run it through the image compressor instead.
Can I convert JPEG to PNG in bulk?+
Yes. Drop up to 20 JPG or JPEG files at once and each one is saved as its own PNG. Download them one by one, or all together as a ZIP. File names stay the same apart from the extension, so beach.jpg becomes beach.png, and two files with the same name get -2 added so nothing is overwritten.
Do I need PNG to make an icon from a JPG?+
Not with ImgWrench. The JPG to ICO converter takes your JPG directly and builds a Windows .ico with every size from 16 to 256 pixels. Convert to PNG first only if another program asks for a PNG, or if you want to remove the background in an editor before making the icon.
Are my JPG files uploaded anywhere?+
No. JPG to PNG runs entirely in your browser, so your photos never leave your device and are never sent to a server. Reading, converting and zipping all happen locally on your computer or phone. You can check this yourself: open your browser's network tab while you convert, and you'll see that no image data is sent anywhere.
