What Is Image Compression?
Image compression reduces the amount of data required to store an image. A smaller image file can be easier to upload, share and store, and can be useful when preparing images for websites.
The amount of compression depends on the image format, image contents and selected quality. Higher compression can produce a smaller file but may also reduce visual quality.
How to Compress an Image
- Select an image from your device.
- Choose the desired compression quality.
- Select an output format if you want to change it.
- Click Compress Image.
- Compare the original and compressed file sizes.
- Download the compressed image.
Understanding the Quality Setting
The quality slider provides a simple way to control the balance between image quality and output file size. A higher quality value generally keeps more visual information, while a lower value can produce a smaller file.
Why Compress Images?
Large image files can take more storage space and may require more data to transfer. Compressing images can be useful before uploading them to websites, sending them to other people or storing many images.
Is the Image Uploaded to a Server?
This tool performs its main compression operation directly in your web browser using standard browser image-processing features. The page does not need to upload the image to a remote compression service.
