Balanced Compression

Smaller File Size
Choose Low when reducing image file size is the main priority, such as when dealing with strict upload limits.
What Is Image Compression?
Image compression is the process of reducing the amount of data required to store an image. A compressed image generally takes up less storage space and can be faster to upload, download and display.
Image compression is especially useful for websites because large image files can increase the amount of data a browser needs to download. Optimizing images can therefore be an important part of creating a faster and more efficient website.
The goal of image compression is to find a practical balance between file size and visual quality.

Reducing image file size can make images easier to store, upload, download and share. Image compression is useful in many everyday situations.

JPG vs PNG vs WebP: Which Image Format Should You Use?
Different image formats are designed for different types of images. Choosing an appropriate format can help you balance image quality and file size.
| Format | Best For | Common Use |
|---|---|---|
| JPG / JPEG | Photographs and colorful images | Photos, blogs and websites |
| PNG | Graphics and transparency | Logos, screenshots and graphics |
| WebP | Efficient web images | Modern websites and web applications |
There is no single image format that is best for every situation. Photographs often work well with JPEG or WebP, while graphics that require transparency may be better suited to PNG.
Can You Compress an Image Without Losing Quality?
Image compression can involve a trade-off between file size and visual quality. With a suitable compression setting, an image can become significantly smaller while maintaining a visually similar appearance.
If maximum image quality is important, choose a higher compression quality. If achieving the smallest possible file size is your main goal, stronger compression may provide greater savings.
The ideal setting depends on the original image, its format and how the compressed image will be used.
