使い方
- 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.
よくある質問
あわせて知りたいこと
Which image formats can I choose?
