Image files that employ JPEG compression are commonly called 'JPEG files', and are stored in variants of the JIF image format. The HEIF specification also defines the means of storing High Efficiency Video Codec (HEVC)-encoded intra images and HEVC-encoded image sequences in which inter prediction is applied in a constrained manner. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography.

In June 2017, Apple announced support for HEIF in macOS High Sierra and iOS 11. It was developed by the Moving Picture Experts Group (MPEG) and is defined by MPEG-H Part 12. High Efficiency Image File Format (HEIF) is a file format for individual images and image sequences.

The target image format can be JPG, PNG, TIFF, GIF, HEIC, BMP, PS, PSD, WEBP, TGA, DDS, EXR, J2K, PNM, SVG, etc.ģ. If this value is blank, the converter will use the estimated quality of your input image if it can be determined, otherwise 92. The value ranges from 1 (lowest image quality and highest compression) to 100 (best quality but least effective compression). Image quality option only works on a few image formats such as JPG, WEBP or AVIF. You can use the original image size or select 'Change width and height' option and enter a custom image size. Set target image format, image quality and image size. You can use file analyzer to get source image's detailed information such as image size, resolution, quality and transparent color.Ģ.
