3Why convert JPEG to PNG?
Understanding the strengths and limitations of each format helps you decide when converting from JPEG to PNG makes sense. Created in 1992, JPEG was designed to efficiently compress photographic images. The name comes from the Joint Photographic Experts Group who created the standard. PNG was created in 1996 as a patent-free alternative to GIF after the Unisys LZW patent controversy. It rapidly became the standard for lossless web graphics.

5Frequently Asked Questions
What is the difference between JPEG and PNG?
JPEG (Joint Photographic Experts Group) and PNG (Portable Network Graphics) serve different purposes. JPEG is an image file format that uses lossy compression to reduce file size without significantly degrading quality. It is widely used for web images and digital photography. On the other hand, PNG is a raster-graphics file-format that supports lossless data compression. It was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF). Converting between them lets you leverage the strengths of each format depending on your needs.
Does converting JPEG to PNG lose quality?
This depends on the formats involved. If the target format (PNG) uses lossy compression, some data may be discarded during conversion. However, if PNG is lossless, your file will be preserved at full quality. Our converter uses the best available algorithms to minimize any quality difference.
