The principle of image compression is to use algorithms to remove redundant data without significantly affecting image quality. This is also the advantage of this capacity reduction method compared to changing the image size. While adjusting the image size can cause image fragmentation (due to pixel loss), reducing the image resolution compared to the original, image compression will limit this situation.

There are 2 popular types of image compression that many people know about:

  • Lossless compression: Reduces image size without changing image quality, compression ratio is usually low.
  • Lossy compression: Reduces image size by removing some of the image’s details, resulting in some loss of image quality.

Why do users need online image compression?

Image compression is a basic technique that users should know to be more flexible in the process of using images. In many cases, high-resolution images come with large capacity, making it difficult to store, share or upload images to websites. Therefore, the image needs to be compressed to reduce capacity, serving the needs of use. Some typical cases and reasons for using online image capacity gain will be mentioned below.

Save storage space for your device

Storing many images at high resolution can quickly fill up memory. Therefore, to optimize storage space on devices, users can find ways to reduce the capacity of images to save a more diverse photo library. Although the hard drives on today’s phones and computers are all expanded, if you do not know how to save data effectively, you will still easily encounter a full memory situation. That is why when you have many photos to save on your computer, phone or portable hard drive, compressing photos will help you save a significant amount of space.

Compressing images will reduce the size without affecting the image quality too much, but on the other hand, it is very effective for storage in the device. For example, if there are 100 JPG images with an average size of 5MB/image, then after compressing at a rate of 50%, the user can save 2.5GB of storage space.

In addition, minimizing memory space for images also helps you optimize space for saving other important documents, downloading necessary software without having to worry about cleaning up full memory due to heavy image files.

Speed ​​up image downloads and sharing

The speed of downloading images depends a lot on the size of the file you download, the larger the image size, the longer it will take to download. This is also true when users upload images to online platforms and share images with others. Therefore, compressing images to reduce capacity is extremely necessary to speed up the process of downloading and sharing images.

In addition, some websites also limit the capacity to a certain level, not allowing users to upload files that are too large. This is also the reason why you should know and use image compression techniques to make sharing easier.

For example, Facebook limits the size of uploaded photos to 5MB per photo. Therefore, compressing images can help you upload larger photos without errors. This also applies when users send photos via Gmail or upload photos to Google Drive, smaller photos will be sent faster and limit the congestion of the recipient’s mailbox.

Optimize website loading speed

Websites need to upload images to serve the purpose of posting and providing information to visitors. However, unoptimized images, especially large images, will affect the page loading speed. A platform that has to store too many large images will slow down the website’s operations, while according to Google, reducing the image size by just 1KB can increase the website loading speed by up to 20%.

There are many ways to optimize images before uploading them to your website, one of which is to compress them to reduce their size, minimizing the strain on your platform. Images with low size but still maintaining their quality after compression will improve website speed, allowing pages to load faster, thereby improving user experience.

Quick and easy to do

Another reason why users should choose to compress images using online tools instead of using specialized software is that this technique is extremely easy to perform. Most websites that support compression are free and easy to use, users just need to access, upload the image and choose the desired compression level. The compression process also only takes a few seconds to complete without requiring the installation of any other third-party applications.
