When compressing JPEG photos, some redundant data is removed. This type of compression is called lossy because some loss of quality occurs no matter what. For this reason, if you apply really strong compression to your images, their quality will degrade drastically. But if you compress your images the right way, you won’t see much of a difference between the original and the compressed copy. Lossy compression can reduce the file size of an image by a lot.
Lossy compression uses the imperfection of the human eye to its advantage. You may not know this, but people pay more attention to the contrast between brightness and darkness than to the contrast between colors and nuanced hues. The way lossy compression works is it gets rid of similar-looking colors and some finer details but doesn’t change bright and dark spots. For this reason, you won’t see much of a difference in quality.
There is no loss or degradation of quality in lossless compression. No redundant data is removed. The image is simply compressed; kind of like a zip-archive. Which is why, when lossless compression occurs, the file size of an image won’t be significantly reduced. Lossless compression is a fully reversible process, which means that you can restore your compressed images to their initial state, which is impossible with the lossy compression.
PNG is a format that is commonly used for digital graphics – logos, icons, images with a lot of text, etc. PNG images cannot be compressed to the same size as JPEGs – they will always be bigger.
GIF is used for files with animation. Even though, it’s a lossless format, GIFs are usually of more manageable size.
Before we dive into image compression, let’s cover some basics. Any file, including an image, has a size. A file size is measured in megabytes and kilobytes. There are 1024 kilobytes in 1 megabyte.
Image compression is an integral part of optimizing visual content for web, because its main purpose is to substantially reduce the size of an image without compromising its excellent quality.
Image compression can be a great solution to several problems. First and foremost, you should never post high-resolution photos of a large size on your website, because they will take a long time to load and subsequently, slow down the loading speed of the entire webpage. People hate it when they have to wait for all the visual content to show up. If your website doesn’t load quickly, your visitors will go to your competitors, and you will lose your potential customers.
However, the smaller the file size of your images, the less space they will occupy on the server and the faster they will load. Therefore, it is essential to compress photos before publishing them on your website if you don’t want to keep your visitors waiting.
You can compress JPEG images in our online app. The process is extremely simple. You need to import your photos, choose one of three options – Best Quality, Smaller Size, Specific File Size – and click on “Compress Images”. That’s it! No matter what option you’ll choose, our image compressor will keep the quality of your compressed files as close to the original as possible.
This is pretty much impossible, if you want to compress a file in lossy format, like JPEG. In lossy compression, removal of some redundant data and insignificant loss of quality is inevitable. However, this isn’t something that you should be worried about. If compression isn’t strong, you won’t see any difference between the original photo and the compressed copy. One thing to keep in mind, though, is if you want to achieve the best results, you will need to use an app that allows you to preserve the best quality when compressing images. Fortunately, our image compressor has this feature.
Our Image Compressor will come to your rescue here as well. You won’t have to download any mobile apps to compress your photos on iPhone or Android. Our website has a great mobile version, which means you can use our online tools in your mobile browser.
