Supporting several formats (PNG, JPEG, JPG, PDF, GIF, etc.).Capacity to optimize images on upload AND the ones already published on your site (the bulk option to compress multiple images).Compressing your images to reduce further file size ( with lossy and lossless compression).Resizing your images to reduce the file size.
When it comes to optimizing your images, make sure that the tool or plugin you are going to choose has the following features:

You may not need the full Adobe Suite but a simpler (and cheaper) tool that offers the same options for image optimization. Still, they also have thousands of features that can be unnecessary if you’re “only” looking to optimize your website’s images.

They are both excellent software for advanced editing. Photoshop and Lightroom are two of the most popular options, but they can be expensive, hard to master, and may not fit everyone’s needs. Instead, detailed information will be taken away when you compress the image.Are you looking for an alternative to Photoshop and Lightroom for image optimization?įinding the right software can be a daunting task. In short, the number of pixels remains intact. This transformation cannot be reversed, but it will improve the speed in which it takes to load your image. Previously, the image had 6 values, whereas following compression, only 3 values are present in the image, which saves up 50%. After you compress the image, the values are 0, 0, 10, 10, 20. Let’s make this easy to understand.īefore compressing an image, each pixel has a different value 0.12, 0.1234, 12.1, 12.123, 21.12, 21.1234. It adjusts the quality of the image by discarding unnecessary data, for example, limiting the colors used in an image fewer colors means there’s less data to run around. It reduces the size of the image without losing a single pixel from the original file. However, when you compress file size, a different algorithm will be applied. If you reduce resolution, the number of pixels will be cut down resulting in a pixelated image. As a result, the resolution of each image is significantly different. These images have a different number of pixels but they fit the image size by expanding each pixel. In summary, pixels have no set size, they just expand or contract to fill the space available.
The more pixel information it has, the higher resolution it is, which results in a crisp image. This article will provide you with an idea of how much image degradation is acceptable versus what file size is too big.įirstly, you may wonder what the difference is between reducing ‘resolution’ and ‘file size.’ Image resolution, generally described in pixels per inch(PPI), refers to the number of pixels in an image. However, there’s a sweet spot where you can make a trade-off between file size and image quality. Compressing JPEG images downgrades the quality of the image. Which explains why we always try to capture images at the largest resolution. However, if your image is already in a high resolution, this change is difficult to distinguish. As a result, fine details in certain areas of the image are obliterated. It uses certain ‘tricks’ based on how the human visual system works to take away information, and the removing information can be barely seen. Lossy compression reduces the file by permanently eliminating what looks like redundant details. JPEG image files, a format commonly used for photographs and other complex still images on the Web, is an image that allows for lossy compression.
