图片压缩
单个JPEG/PNG/WebP输入，输出JPEG/WebP；不覆盖参考站所有格式与批量。
使用步骤
如何使用
- Choose a JPEG, PNG, or WebP image.
- Choose JPEG or WebP, adjust quality, and select Compress image.
- Review the preview and file size, then download the result.
A quick local workflow
The compressor reads the selected image in your browser and prepares the result there. Your file does not need to be uploaded to use this page.
Quality is a tradeoff
Lower quality usually produces a smaller file, while higher quality preserves more visual detail. Already optimized images can sometimes become larger after conversion.
常见问题
你可能还想知道
Which image formats can I choose?
You can select JPEG, PNG, or WebP input images.
Will the dimensions change?
No. Compression keeps the source image dimensions.
Can a compressed file be larger?
Yes. An already optimized source may not benefit from another encoding pass.
