Format descriptions
JPG — JPG (JPEG) is the most widely used image format in the world. It uses lossy compression to reduce file size, making it ideal for photos and complex images, but it does not support transparency.
PNG — PNG is a lossless raster format that supports transparency. It is ideal for logos, graphics and screenshots because it never loses quality, although files can be larger.

What happens when converting JPG to PNG?
Transforming JPG to PNG converts lossy DCT photographic data into a lossless Deflate raster container. This prevents any further generational quality loss during subsequent editing or saving cycles, making it the ideal intermediate step for graphic design and compositing, even though it cannot restore detail already discarded by the original JPG.
Frequently Asked Questions
What is image conversion?
Image conversion changes an image file from one format to another, for example from JPG to PNG, while keeping the image content.
Are my images uploaded?

Which image formats are supported?
This tool converts JPG images to PNG, all in your browser.

Does it work on mobile too?
Yes, it works on any modern device, including smartphones, tablets and desktop computers.
Which format will the result be in?
The converted image will always be in PNG format, ready to download and use.
What happens to transparency when converting to JPG?
JPG does not support transparency. If your image has an alpha channel (for example a PNG or WebP with a transparent background) and you convert it to JPG, the transparent areas are flattened and may appear with a dark or black background. Use PNG, WebP, TIFF or GIF output to preserve transparency.
