Optimizing a photo is a crucial step you need to take prior to publishing it on the Internet. Compression plays a key role in image optimization, since it allows you to reduce the size of your visual content dramatically and without a significant loss of quality. The difference between the original photo and the compressed copy tends to be practically unnoticeable to the naked eye. What’s more, this extremely simple process won’t take long. However, to achieve the best results and preserve the superb quality of your visual content, you need to know how to compress an image the right way.
Compress Image For FreeYou’re probably wondering what the purpose of image compression is. Well, here’s the answer.
When you downsize your image by compressing it, you can:
Most often, the need to compress photos arises when they have to be uploaded onto a website. High-resolution images of a large size will impact your website’s loading speed negatively. In other words, even though your photos will look great, they will take an eternity to load. Researchers have already established that if it takes more than 3 seconds for a webpage to load, visitors will leave and look for what they need elsewhere.
Today, people have a dazzlingly vast choice of products and services, which, naturally, have spoiled them and now, they will simply refuse to spend a lot of time and effort to buy something they want. Thus, it’s your job to optimize your website and make it load with a lighting fast speed. If you don’t provide your customers with great shopping experience, they will go to your competitors.
Another point worth noting is that even if you don’t have your own website, you might still need to compress your images. Quite a lot of websites have limits on the size of photos for upload. For example, profile pictures usually have to be of a relatively small size. A website will refuse to upload an image, the size of which won’t comply with their requirements, and prompt you to choose another photo. This issue can also be easily solved with compression of image files.
Compress Image For FreeCompressing an image means reducing its size in bytes while keeping its quality at an acceptable level. If you don’t zoom in too much, the original and the compressed copy will appear to have the same excellent quality. The important bit of information to know, though, is that different types of compression exist – lossy and lossless – and image formats tend to support one type of compression, but not the other.
If you compress photos correctly, you can easily reduce their size by 70 – 90%.
There are two main ways to compress photos:
Lossy compression relies a lot on the imperfections of the human eye. When you compress JPEG images, the compression algorithm targets similar hues and color transitions. Human eye detects the difference between darkness and brightness much better than the difference between colors. This is why black and white photos can have a lot of depth and details. Whereas, if you get rid of all the bright and dark spots in a photo, you will be left with splotches of color and no sense of dimension. Thus, lossy compression tends to retain the contrast of brightness and darkness, sacrificing similar hues instead.
Compress Image For FreeYou can compress an image using various online services and software. Even some standard programs that all Windows and Mac computers have allow you to reduce the size of your photos by compressing them. In other words, it’s quite an easy thing to do, and you won’t need any image editing skills.
However, Watermarkly’s online image compressor will simplify this process as much as possible, while also making sure that your images are compressed the right way. There will be no need for you to download or install our app on your computer, search for drivers or plugins. You will get your compressed copies within minutes!
A website or social media platform can automatically compress images of large size, if you decide to publish them online. This may lead to degradation of their quality – your photos might turn blurry and pixelated. If you want your visual works to look good on a website or social media, you’ll have to reduce their size by compressing them in an app that was specifically designed for this purpose.
Watermarkly works with three popular image formats:
Most JPEG images can be compressed without significant loss of quality. So do PNG and GIF.
Our image compressor reduces the size of your images by removing redundant information from them.
Our app will do its best to preserve excellent image quality as much as possible and ensure that your compressed photos look just as good as the originals.
If you choose the first or second option, you will see the size of your compressed images in bytes only after the process is finished.
When compressing an image, Watermarkly does everything in its power to keep the quality of your compressed photos at the level of the originals yet reduce their size from megabytes to kilobytes.
If you need to urgently compress photos that are stored on your phone, you won’t have to transfer them to your computer – you can use our app in your mobile browser. Just open our website and go to the Compression page. The mobile version of Watermarkly looks and works exactly like the desktop one. The process is the same – import your photos and choose the option of image compression that suits your needs. Depending on your choice, compressed copies will be saved to your phone’s gallery or one of the cloud storages.
With our online tool, you will be able to compress an image on Mac, Windows or any other operational system. It can also work on a smartphone. No matter if you have an iPhone or a device with Android OS, you can easily compress your photos anywhere you are – as long as you have the Internet access.

Compress Image For FreeThere are three formats that are widely spread:
The vast majority of images you see on the Internet are JPEGs, which isn’t surprising since this format is perfect for photos that have a lot of details and colors. You can apply a strong compression to JPEG images to dramatically downsize them, but it may degrade their quality – it’s a lossy format, so you have to be careful. With the right amount of compression, however, you can achieve spectacular results. What you also need to know is that JPEG doesn’t support transparency and isn’t suitable for images that have a small amount of color data; for example, screenshots. Even if you’re not going to compress them, it’s better to save screenshots as PNG.
This format handles sharp edges and less subtle color transitions much better than JPEG, which is why it’s most commonly used for logos, icons, and images with a lot of text. This format is very versatile since it supports transparency and lossless compression, which means when PNG files are compressed, no data is lost. However, compressed PNGs always have a bigger size in bytes than compressed JPEGs. Also, this format isn’t suitable for highly-detailed images liked photographs.
This format also supports lossless compression, but, at the same time, GIFs tend to be of more manageable size than PNGs. GIF can covert images into animations, therefore it is usually used to create files with animation. It has some downsides as well: it doesn't support blended boarders or shadows, offers a rather limited choice of colors and doesn't convey dimensions all that well. Moreover, it is a bit challenging to compress GIFs, because the result might look a bit pixelated and, generally, not very good.
Compress Image For FreeWe have prepared several answers to the most popular questions on how to compress an image and hope that you will find them useful. However, if something remains unclear to you, you can contact our support service.
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.
Usually, it is necessary to downsize images before posting them on your website, because large-sized, high-quality images might dramatically slow down the loading speed of your webpages. Also, some websites and social networks have a limit on the size of images that can be uploaded to their platforms. So, if you want your photo to be small enough to be uploaded, yet still look great, you will need to compress it. This process won’t take long if you use Watermarkly.
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, Watermarkly has this feature.
Generally speaking, if you want your compressed images to look good, you should avoid really strong compression. Of course, it is possible to reduce the size of your JPEG to 5 percent of its original, but it will lead to a dramatic, evident degradation of quality. Don’t forget that when lossy compression occurs, some data gets removed. Since compressed JPEGs contain less information than the original, some elements like level of sharpness or subtle color transitions might disappear.
Usually, yes. You do. Most mail services have a limit on the size of attachments that you can send – it's somewhere around 25 MB per letter. To send a bunch of photos that collectively exceed this limit, you will need to compress them first. With our app, you can easily do this in a matter of minutes.
Watermarkly 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. The process of compressing images is the same as in the desktop version – upload your photos, choose the level of compression that you want, and download your compressed copies.
For a number of reasons. When you compress photos, you downsize them from megabytes to kilobytes, which will allow you to send them over an email or free up a lot of memory space on your device. You will also be able to upload your compressed photos to various social media platforms without worrying about size limits.
