About 图片压缩
直接在浏览器中使用此工具,提供清晰选项,并在可用时进行本地隐私处理。 Use it when you need the result without the overhead of opening a larger application. For anything important, compare the output with your source and keep the original until you are satisfied with the result.
Optimize for the destination, not the smallest number
A useful compressed image is one that meets the upload or performance goal without making important detail look damaged. Fine text, hair, gradients and sharp product edges show artifacts before broad areas of color do.
开始 from the best source, resize if the dimensions are excessive, then lower quality gradually. Repeated lossy exports can accumulate visible damage, so keep the original as your master copy.
A realistic example
For an email attachment, try a moderate quality setting and compare at 100% zoom before pushing lower just to save a few extra kilobytes.
When this tool is not the right fit
If exact pixel preservation is required, use a lossless workflow instead of aggressive lossy compression.
