How to use it
- Drop your JPG images into the box, or pick them from your device.
- Each one is saved as a PNG in your browser.
- Download the PNG files one at a time or as a ZIP.
What changes when you convert JPG to PNG
The new PNG holds exactly the pixels of the JPG, saved without any further loss. It does not bring back detail that JPG compression already removed, and it does not make a picture sharper. What it does give you is a format that stops losing quality each time you open and save the file, and one that many design tools and web builders accept.
Common reasons to use PNG
People convert JPG to PNG when a tool only takes PNG, when they want to edit an image several times without adding new compression damage, or when they plan to add transparency in an editor afterward. The converted file has no transparent areas yet, because a JPG never contained any.
File size
Expect the PNG to be larger than the JPG, often by a wide margin for photographs. If you want to reduce size instead, the PNG to JPG converter or the image compressor on this site can help.
Frequently asked questions
Are my files uploaded anywhere?
No. The conversion runs inside your browser on your own device. Your images are never sent to our server or to anyone else. You can confirm this in your browser's developer tools: the network tab shows no image data leaving the page.
Does converting JPG to PNG improve quality?
No. It stops further quality loss from later saves, but it cannot restore detail already lost in the JPG.
Will the background become transparent?
No. The picture keeps its original background. Use an image editor to remove it if you need transparency.
Can I convert several JPG files together?
Yes. Add up to 100 files and download the results as a ZIP.
