Why convert JPG to PNG?

JPG and PNG serve different purposes. Converting between them lets you use whichever format works best for your situation.

What is a JPG file?

Joint Photographic Experts Group: JPEG is the default format for photographs. If you've taken a photo with your phone or downloaded an image from the web, chances are it was a JPEG. It uses lossy compression to keep file sizes small while maintaining reasonable visual quality.

Created by: Joint Photographic Experts Group (ISO/IEC), first published in 1992

Used for: Photographs, web images, email attachments, social media uploads

Technical details: Lossy compression with adjustable quality. Higher quality means bigger files. Does not support transparency. Works best for complex images with lots of color variation like photos.

Compatibility: Universally supported on every device, browser, and platform.

What is a PNG file?

Portable Network Graphics: PNG is a lossless image format that supports transparency. It was created as a patent-free replacement for GIF back in the mid-1990s and quickly became the standard for web graphics that need clean edges or see-through backgrounds.

Created by: PNG Development Group, first released in 1996

Used for: Web graphics, logos, screenshots, icons, anything that needs transparency or sharp text

Technical details: Lossless compression, so the image looks identical to the original. Supports 8-bit and 24-bit color with an alpha channel for transparency. File sizes tend to be larger than JPEG for photos but smaller for graphics with flat colors.

Compatibility: Every browser, operating system, and image editor supports PNG. It is one of the most universally readable formats.
