Tinypng is our go-to tool to quickly up and download an individual image. Quick aside – here’s a couple of other tips alongside image compression… A 1MB file is more than adequate for even a high resolution background image. What’s more, image files don’t need to be that big for a website. ![]() Whether you upload content to your website yourself, or outsource this to a third party, the larger your image files, the longer they will take to upload. A compressed image takes less time to upload If you want to see if images are a problem for your website, just use this free google tool to see how quickly your website loads. Ensuring all of your images render quickly is a major reason why image compression is important. If this takes 2.5s or less, you get a good score. In layman’s terms, LCP is simply the time it takes for your largest image (or content block) to fully render on a device. One of the three metrics it tracks is your website’s ‘largest contentful paint’ (LCP). In late 2021, Google included its performance analysing ‘Core Web Vitals’ in its search algorithm. Not only is this great for user experience, it also improves search engine optimisation (SEO). Here are 5 reasons why image compression is important: A compressed image loads fasterĪ compressed image will download from your website and render on a visitor’s screen faster. However, the level of visual detail is often redundant for use on a website, which is why further image compression is often necessary. This gives them maximum versatility for print or digital use. Photographers will often provide their clients with minimally compressed JPEG files. similar shades of a colour may be rendered identically). ‘Lossy’ compression methods, such as JPEG, can compress the files even further, but approximates some of the details (e.g. ‘Lossless’ compression methods, such as PNG, retain all of the information needed to construct an exact replica of the original file. In order to preserve as much detail as possible, these files are huge and offer lots of flexibility for editing with programmes like Photoshop.Ĭompression methods such as JPEG and PNG, use algorithms to create images that are much smaller in size. When a digital camera produces a digital image, it will carry out minimal processing to create a ‘raw file’. What exactly is image compression, anyway?īefore looking at why image compression is important, it is useful to understand exactly what it is. Potential issues with image compression. ![]() Image compression doesn't affect resolution.A compressed image takes up less storage space.A compressed image takes less time to upload. ![]() What exactly is image compression, anyway?.Selecting a region changes the language and/or content on Cooper Videographer What we will cover So, when you need to decide between compressing an image and resizing it, think ahead to what you may need that image for in the future - and always keep a copy of your original picture, just in case. This comes in handy when you need to store your down blanket away for the summer, but you might regret it when winter comes around. The aspect ratio - that is, the dimensions of length and width - will be different than before. With image resizing, think of it as tailoring your blanket from a king size to a twin size. In both cases, you still have the same basic blanket, but one will be slightly fluffier than the other. Or, if you need to make the blanket even smaller, you could remove some of the feathers before packing it up. Think of it like a fluffy down blanket - you can reduce its size by packing it into a box. However, there are critical differences between the two techniques that you should know if you want to set up your image files for success.Īs you learned above, image compression reduces the amount of visual information in a file. Compression and resizing are similar concepts - both can make your file sizes smaller.
