Image is always implemented by a pixel-specific Image instance. Complete support for jpeg, bmp, gif, pbm, png, tga, tiff, and webp with more formats on the way. meaning that the caller is not allowed to dispose pixelMemoryOwner. allowing to view/manipulate it as an Image instance. The ownership of the pixelMemoryOwner is being transferred to the new Image instance, IMO, as long as the Image comes out the same (you can compare them using some sort of MD5 tool), it doesn't matter if the size of the file is different when you save it, as the actual image is still the same as the original. Checking the base64 of the whole file to confirm the images are the same is not the same as comparing just the images. data:image/gif;base64,R0lGODlhAQABAIABAEdJRgAAACwAAAAAAQABAAACAkQBAA==, PixelAccessorAction, SixLabors.ImageSharp.ColorSpaces.Companding, SixLabors.ImageSharp.ColorSpaces.Conversion, IImageFormat, SixLabors.ImageSharp.Formats.Tiff.Compression, SixLabors.ImageSharp.Formats.Tiff.Compression.Decompressors, SixLabors.ImageSharp.Formats.Tiff.Constants, SixLabors.ImageSharp.Metadata.Profiles.Exif, SixLabors.ImageSharp.Metadata.Profiles.Icc, SixLabors.ImageSharp.Metadata.Profiles.Iptc, SixLabors.ImageSharp.Metadata.Profiles.Xmp, SixLabors.ImageSharp.Processing.Extensions.Transforms, SixLabors.ImageSharp.Processing.Processors, SixLabors.ImageSharp.Processing.Processors.Binarization, SixLabors.ImageSharp.Processing.Processors.Convolution, SixLabors.ImageSharp.Processing.Processors.Dithering, SixLabors.ImageSharp.Processing.Processors.Drawing, SixLabors.ImageSharp.Processing.Processors.Effects, SixLabors.ImageSharp.Processing.Processors.Filters, SixLabors.ImageSharp.Processing.Processors.Normalization, AdaptiveHistogramEqualizationSlidingWindowProcessor, SixLabors.ImageSharp.Processing.Processors.Overlays, SixLabors.ImageSharp.Processing.Processors.Quantization, SixLabors.ImageSharp.Processing.Processors.Transforms, IResamplingTransformImageProcessor, https://en.wikipedia.org/wiki/Data_URI_scheme, data:image/gif;base64,R0lGODlhAQABAIABAEdJRgAAACwAAAAAAQABAAACAkQBAA==. Metadata editing support (IPTC EXIF). Compared to System.Drawing, ImageSharp uses more modern paradigms like memory management, thread safety, and functional styles, and strives to be flexible and extensible.

It does not "remember" the original image format. either Byte or TPixel values, it is highly recommended to use one of the other 1. No encoder available for provided format.
