How to use it
- Drop your PNG images into the box, or pick them from your device.
- Set the quality under Options if you want a smaller or sharper result.
- Download each JPG, or get them all in one ZIP.
Why turn a PNG into a JPG?
PNG files are lossless, which makes them large, especially for photographs and screenshots with lots of color. JPG uses lossy compression and can shrink the same picture to a fraction of the size. That helps when you email images, upload them to a site with a size limit, or want a web page to load faster.
When to keep the PNG
Keep the PNG if the image has sharp text, thin lines or flat colors, such as a logo or a diagram. JPG can add faint blur around edges in that kind of image. PNG is also the only choice of the two when you need transparency.
Transparent PNG files
JPG cannot store transparent areas. When a PNG with a transparent background is converted, the clear parts are filled with a solid color. White is the default, and Options lets you choose another color before you convert.
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.
How much smaller will the JPG be?
It depends on the picture. Photos often shrink a lot, while images with flat colors shrink less. The quality slider controls the result.
What quality setting should I use?
Around 80 to 90 percent suits most uses. Go lower for the smallest file, or higher if you plan to edit the image again.
Will I lose quality?
Some, because JPG is a lossy format. At 90 percent the difference is hard to see in photos.
