Reduce image size online without breaking the image, keeping the original quality

You have a beautiful photo that you want to send to your friends or upload to the website but the size is too large? The photo reduction tools below will help you quickly reduce the size of the photo but still keep the same quality and clarity as the original photo.

Why do you need to reduce image size?

1. If your purpose is to post images on the website - a low-resolution image will help increase the time and speed of your website loading. Of course, a small image will take less time to download, helping the website content to display faster, helping the user interact with the website faster. This is also a factor that is considered quite important if you are building content and SEO for the website.
2. If you store compressed JPG and PNG images on your mobile devices, you will save up to 80% of your device's memory compared to keeping the original size. This means that by reducing the size of the image, you will significantly free up the memory of your laptop or phone.
3. And of course, reducing image size will help you share high-quality images via social networking or communication platforms like Facebook, Zalo, Skype faster.
