About Image Compression
The image compression tool can effectively reduce image file size while maintaining good visual quality. Supports compression of JPEG, PNG, and WebP formats, and you can customize the compression quality according to your needs. The compression process is done entirely locally in the browser, and images are not uploaded to any server.
FAQ
What image formats are supported?
Currently supports compression of JPEG, PNG, and WebP formats. These three formats cover the vast majority of use cases. Other formats (such as GIF, AVIF) are not supported for compression.
How to choose compression quality?
The lower the compression quality, the smaller the file, but the image quality will also decrease accordingly. It is recommended to start with 80%, and if the file is still too large, you can gradually reduce the quality. For web use, 60%-80% usually achieves a good balance between file size and quality.
Will compression lose image quality?
JPEG and WebP are lossy compression formats, and there will be some quality loss during compression, but at higher compression quality (such as above 80%), the human eye usually cannot detect the difference. PNG is a lossless format, and compression will not lose quality, but the compression effect is relatively limited.
Can compressed images be restored to original quality?
No. Lossy compression (JPEG, WebP) is irreversible, and compressed images cannot be restored to original quality. It is recommended to backup the original image before compression, or keep a higher quality setting during compression.
