PSD to GIF converter

.psd

Adobe Photoshop

PSD – is an image file format created by Adobe for Graphic Designers to create layered images. With this format, a wide range of data from "Photoshop" is available, including texts, graphic layers, or notes. The extension can support multiple shades of gray, monochrome images, as well as CMYK and RGB color models. Such files can be converted to various formats (JEPG, PNG, and others) for subsequent transfer or storage. After changing the format, all the layers are transformed into one, which does not happen when saving with the PSD extension. In this case, they are available for viewing and editing, making them especially useful for working with drafts of various documents. The format is irreplaceable when saving the intermediate results. It is supported by most versions of Photoshop, as well as other Adobe programs.

The PSD extension is characterized by the ability to support various visualization options, including a mask, spot colors, two-color settings, clipping. There are files with the .psb extension in some cases, which support a resolution limit of 30 thousand pixels in width and height. PSD files use the RLE compression algorithm, which allows compressing with minimal loss. However, they are still large, so it is better to use archivers for storing them on disk.

.gif

GIF, Graphics Interchange Format, is one of the most popular bitmap image formats on the World Wide Web, allowing you to share images. It also supports transparent views of various animations. Such files are used to develop web advertising with sequentially changing pictures and the graphics shell of video files. They use scan-line images with the depth parameters up to 256 colors of the RGB palette. The process of compressing files in GIF does not affect the quality in any way, as there is no loss because of the compression technique. Due to this, it is possible to convert to other formats while preserving the original image properties. Many applications open the extension to view and process images and video content installed on PCs and mobile devices regardless of OS.

The format was developed by Compuserve specialists, especially for its use in the web environment, which provided broad public access to data on such files. The extension uses the LZW algorithm to carry out a parallel process with the removal of segments containing insufficient information. This ensures the preservation of high-quality pictures. Thanks to the Lempel-Ziv-Welch algorithm, the format handles graphic files with repeating sections well, particularly images with a large number of single-color pixels horizontally. Interlaced data storage is also possible. Scan-line data is compressed to the smallest size. Reducing the number of colors required to create an image is provided by removing shades unnecessary to perform this process. The range of available GIF colors is from 2 (black and white) to 256 while reducing the number of colors leads to a decrease in the file size.
