Why convert JPG to PNG?

The main difference: JPG is a lossy format, while PNG is a lossless format. PNG can have a transparent background, JPG can't.

Stop losing quality on every save

A JPG is re-compressed each time you edit and save it, and a little detail goes every time. PNG is lossless: it keeps every pixel exactly as it is, however many times you edit it.

Supports transparent backgrounds

PNG can hold a transparent background. Convert your image first, then cut out the background or place it on top of other designs.

Crisp edges for editing and print

PNG keeps sharp lines and text intact, which makes it the better choice for graphics, screenshots and anything you plan to print.

What is a JPG file?

JPG (also written JPEG, from the Joint Photographic Experts Group that created it in 1992) is the most widely used photo format in the world. Phones, cameras, websites, email and social networks all handle it.

JPG uses lossy compression: it discards fine detail your eye barely notices, which makes photos 5-10 times smaller than an uncompressed copy. The trade-off is that every re-save loses a little more detail, and it can't store a transparent background.

How to open a JPG file

Every device opens JPG files out of the box: Photos on Windows and Mac, the Photos or Gallery app on iPhone and Android, and any web browser. To edit one, use Photoshop, GIMP, Canva or the free tools on ConvertPixels.

What is a PNG file?

PNG (Portable Network Graphics) is a lossless image format created in 1996 as a patent-free replacement for GIF. It stores every pixel exactly, so text, logos and sharp edges stay perfectly crisp however often you save the file.

PNG supports full transparency, which makes it the standard format for logos, icons, screenshots and graphics placed on top of other designs. For photos, though, PNG files are several times larger than JPG.

PNG opens everywhere: Windows Photos, Mac Preview, iPhone and Android galleries and every web browser. Editors like Photoshop, GIMP, Figma and Canva keep the transparency intact.
