16 bit photo converter online11/19/2023 PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without alpha channel), and full-color non-palette-based RGB images (with or without alpha channel). Luckily, you can disable saving images as HEIC on an iOS 11 device by going to Settings > Camera > Formats > Most Compatible, which will force iOS 11 to save images in the JPEG format. Third-party apps or computer programs can still have difficulties interpreting HEIC files, though. ![]() However, HEIC files still have compatibility issues, even though they are already posted and saved to social media or cloud storage as JPG images since they are automatically converted. With transparency and the ability to store more than one image, HEIC files can also contain 16-bit colors, whereas JPG files can only support 8-bit. The lossy compressed HEIC format is based on HEVC (High-Efficiency Video Compression), also developed by MPEG. However, PNG itself does not support animation at all. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF) and is the most used lossless image compression format on the Internet. Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. Furthermore, it stores information about image editing like rotation and cropping, which enables the user to revert the changes later on. Furthermore, HEIC files can contain several images which fit Apple's "Live Photo" functionality. As a result, it's smaller in size with comparable quality while also supporting transparency. Being the new default or standard image format for iOS 11 devices, HEIC was designed to replace the JPG format. The HEIC format was developed by MPEG (Moving Picture Experts Group), otherwise known for video and audio formats such as MP3 or MP4. It is also known under the acronym of HEIF, which stands for High-Efficiency Image Format. If you select the "User-defined Weights" option, then you can also create your own custom conversion formula by manually entering the weights that determine how much light is extracted from each color channel.HEIC is the new standard image format introduced by Apple with its 2017 update from iOS 10 to iOS 11. The second method is called the "ITU-R BT.709 Formula," (also known as HDTV formula), which applies different weights to the color channels according to the formula "0.21×Red + 0.72×Green + 0.07×Blue", and the third method, known as the "ITU-R BT.601 Formula," (also known as PAL/NTSC formula) utilizes the formula "0.30×Red + 0.59×Green + 0.11×Blue". Among the most popular conversion formulas are the "Average Color Values" formula, which takes equal amounts of red, green, and blue channels and calculates their average value as "(Red+Green+Blue)/3" for the amount of light left in the image. This tool provides the three most popular grayscale conversion formulas as well as gives you the freedom to create a custom formula. There are also multiple methods for removing the color information from an image. ![]() As the information about the amount of color is lost, we obtain a grayscale or a black-and-white image. To create a grayscale image, the tool removes information about how much color is in each of these channels and leaves only information about the amount of light in these channels. ![]() These three colors are stored in three separate color channels, called the red color channel, the green color channel, and the blue color channel. By combining various amounts of these three colors together, we get images of all possible colors. ![]() As you may know, all colors that you see in images are actually made out of just three primary colors – red, green, and blue. This tool converts color images into grayscale images.
