PNG stands for Portable Network Graphics. It was created in the mid-1990s as a free and open alternative to the older GIF format. PNG was officially released on October 1, 1996, and later adopted as a standard by the W3C (World Wide Web Consortium).
PNG is best known for supporting lossless compression which means the image quality stays exactly the same after saving. It also supports transparent backgrounds, making it useful for web design, logos, and UI elements.
However, PNG files are usually larger than JPEG or WEBP because they don’t remove any image data. This makes PNG ideal when image quality and sharpness are more important than file size.

AVIF stands for the AV1 Image File Format. It uses the AV1 video codec inside a HEIF (High Efficiency Image File Format) container. AVIF was released in February 2019. This format compresses images better than JPEG and WebP, creating smaller files without losing quality.
AVIF supports high dynamic range (HDR), wide color gamut, transparency, and animation. These features make AVIF good for photos and websites.

- Windows: Use the AVIF Extension for Photos app, or open with IrfanView, GIMP, or XnView MP.
