Whether you're a designer, blogger, or salesperson, there will always be times that you need to compress your images. Fortunately, there are many free online image processing tools that can be used for image compression that don't degrade sharpness too much. let's see!
First let's get some information of the difference between compression, resizing, and conversion.
Compression is the reduction of file size while keeping the resolution the same. Of course compression too much may degrade image quality, so finding a balance between speed and visual effect is important.
Resizing is changing the visual resolution of an image. For example, an image that is 2000px wide x 1100px tall will be resized to 500px wide x 275px tall, which will significantly reduce the size of the image after resizing.
Convert is a different concept from the previous two, primarily by converting an image format to a different type format. Usually, the image size will not change, but will change the size of the image after converting.
Image formats supported by the tool
There are differences in the image formats supported by different image compression tools. Please make sure that the compression tool you want to use complies with the compression of your image format.
Limitations of Uploading
Please check whether the tool supports batch uploading and whether there is a limit on the size of images to be uploaded.
Is it free to download compressed results
To download the compressed result, you need to check whether it is free or not. Generally, there are three types of downloads: direct download, ZIP file, and download to cloud storage.
Whether compression is customized
The size of image compression will vary with different quality levels. A fixed quality may not meet everyone's needs. It is best to support customized quality adjustment to control the compression level.
