Steps:

1. Click "Choose File" button to select a file on your computer. You can also click the dropdown button to choose online file from URL, Google Drive or Dropbox. The image format can be JPG, PNG, GIF, SVG, WEBP or DDS.

2. Different image formats use different optimization options.

JPG - For the JPEG image formats, JPG quality is 1 (lowest image quality and highest compression) to 100 (best quality but least effective compression).
PNG - PNG compression type can be lossy compression or lossless compression. The lossy compression works like "Save for Web" function in Adobe Photoshop. For the lossy compression, PNG quality is 0 (lowest image quality and highest compression) to 100 (best quality but least effective compression). For the lossless compression, PNG optimization level is 0 to 7 (highest compression). The optimization level 0 enables a set of optimization operations that require minimal effort. The optimization levels 2 and higher enable multiple IDAT compression trials; the higher the level, the more trials. You can use lossless compression after lossy compression to get maximum compression ratio.
GIF - Sets the GIF optimization level from 1 to 3 (highest compression). Level determines how much optimization is done; higher levels take longer, but may have better results.
SVG - SVG compression type can be lossy compression or lossless compression. No optimization option is required for lossless compression. The optimization will remove redundant and useless information. This can include editor metadata, comments, hidden elements, default or non-optimal values and other stuff that can be safely removed or converted without affecting the SVG rendering result. Set number of digits in the fractional part from 0 (highest compression) to 8 if lossy compression is chosen. 3 digits are usually high enough for web graphics.
WEBP - For the WEBP image formats, WEBP quality is 0 (lowest image quality and highest compression) to 100 (best quality but least effective compression). Please note it only works on non-animated WEBP images.
DDS - Sets the DDS compression to DXT1 (highest compression) or DXT5. For an image with no alpha using DXT1, compression results in an image using 4 bpp (bits per pixel). For an image using DXT5 incorporating an alpha channel, the requirements will be 8 bpp.

About:

Image files are composed of digital data in one of image file format that can be rasterized for use on a computer display or printer. An image file format may store data in uncompressed, compressed, or vector formats. A raster graphics image is a dot matrix data structure, representing a generally rectangular grid of pixels, or points of color. As opposed to the raster image formats , vector image formats contain a geometric description which can be rendered smoothly at any desired display size.

You can use this online image compressor program to compress JPG image, compress PNG image, compress GIF image, compress SVG image, compress WEBP image or compress DDS image etc.
