What is the difference between png and psd

The difference between png and psd: 1. PNG can save pictures with transparent background, adding some features that the GIF file format does not have; 2. PSD has high image quality and precision, can be layered, easy to edit, and can be stored into RGB or CMYK mode, and can also customize the number of colors and store them.

The difference between png and psd:

• PNG: advantages (can save pictures with transparent background), disadvantages (loss of image quality)

• PSD: Advantages (high image quality and precision, can be layered, easy to edit), disadvantages (the file is too large, not conducive to transmission, and there are few software that can open it)

1. PNG

The PNG image file storage format is designed to try to replace the GIF and TIFF file formats, while adding some features that the GIF file format does not have. When PNG is used to store grayscale images, the depth of the grayscale image can be up to 16 bits. When storing color images, the depth of the color image can be up to 48 bits, and it can also store up to 16 bits of alpha channel data. PNG uses a lossless data compression algorithm derived from LZ77, which is generally used in JAVA programs, web pages or S60 programs because of its high compression ratio and small file size.

2. PSD

PSD is a special format for Adobe’s graphic design software Photoshop. PSD files can be stored in RGB or CMYK mode, and can also customize the number of colors and store them. It can also save Photoshop layers, channels, paths and other information. It is currently the only format that can support all image color modes. However, it is bulky and can be used universally in most graphic software (such as cdr ai ae, etc.). It can also be used in some other types of editing software, such as the office series. However, image files in PSD format are rarely supported by other software and tools. Therefore, after the image is produced, it usually needs to be converted into some common image formats (such as: jpg) so that it can be output to other software for continued editing.
