FAQ
What is the image quality after compressing to a specific size?
Our smart compression algorithm achieves the target file size through multiple iterations while maintaining the best possible image quality. If the target size is set too small, it may affect image clarity.
What happens if the original image is already smaller than the target size?
If the original image file size is already smaller than your target size, the system will keep the original image without additional compression to maintain the best image quality.
Why can't some images be compressed to a very small target size?
The final compressed size depends on the complexity of the image content. Highly complex or detail-rich images may not be able to reach very small target sizes even with maximum compression. Consider adjusting the target size or resizing the image dimensions as well.
