FAQ
How's the quality after compression?
We use smart compression algorithms to significantly reduce file size while maintaining visual quality. You can adjust compression quality to balance size and quality.
Why does the compressed image have a larger file size?
The increased file size after compression is usually due to the original image being highly compressed, which can lead to an increase in size when compressed again. We recommend using the original image for compression.
Is there a size limit for compression?
Since compression is done locally, file size is mainly limited by your browser's memory. We recommend files under 50MB.
