Where are the PSD, JPEG and TIFF formats used in saving formats in PS?

Hello poster

Let me explain it to you in detail

1 PSD format: This is Photoshop’s own format and can support all Photoshop information: Alpha channel, spot color channel, multiple layers, paths and clipping paths, it also supports any color depth and image mode used by Photoshop. The PSD format uses RLE's lossless compression, and it is also faster to save and open this format in Photoshop. This format should be used for later modification or adding information to the file.

2 JPEG:

Strictly speaking, JPEG is not an image format, but a compression computing technology. This format is lossy compression, and its compression amount can be adjusted to change the file size. Therefore, it is used by the web like the GIF format. JPEG does not support alpha channels, nor does it support transparent images, but it does support paths. It supports RGB mode and also supports CMYK mode. It is suitable for tonal continuous or photographic images. You can select the amount of compression when saving an image in PEG. The smaller the amount of compression, the better the image quality. Generally used in web images and most real-life fields that require long storage.

You have options when saving in this format:

1·Baseline (Standard) The generated file is accepted by all browsers.

2·The baseline has been optimized. The generated file is smaller, but some programs do not accept it.

3·Continuous files are larger, you can select the number of scans, and they can be displayed gradually when loading. But not all browsers support it.

3 TIFF:

TIFF supports bitmap, grayscale mode, index mode, RGB, CMYK, and Lab image modes. It is a cross-platform image format that can be opened and stored in both Windows and Macintosh. It is widely accepted by page layout programs and is commonly used in the publishing and printing industries.

I hope my answer can help you and please accept it to your satisfaction
