You can even set a custom chroma subsampling value for JPEG images. Using this mode you can set different quality levels for lossy JPEG and PNG optimization, preserve certain entries in the EXIF metadata, and automatically orient your images. ExpertĮxpert view is designed for users who are already familiar with image processing and optimization. Use this mode when your requirement is that the image should retain 100% of its initial visual information - such as for sensitive brand and marketing visuals. This mode will save as much file weight as possible without altering a single pixel, hence the name "lossless" - meaning no information is lost whatsoever. We recommend this mode to most of our users, and for most use-cases. Other features include: Drag-and-drop feature for easier compressions. With Compressor.io, you can optimize SVG, GIF, JPEG, and PNG files.
In most cases, you will not be able to tell the optimized result from the original, even upon close inspection. Pick between lossless or lossy image compression to determine the file size and image quality this is made simple and is very fast. Our default intelligent lossy algorithm has been specifically designed to always produces images of outstanding quality, and never of unacceptable quality degradation. Our intelligent lossy optimization typically produces savings of at least 60% of the initial file weight with savings of 80% to 90% occurring frequently. The mode you select should depend on your specific requirements - such as the type of image that you are compressing, and the target audience of your images.
Kraken.io offers several optimization modes.
