给简报准备照片时，“均衡”档位是个好起点。把处理前后的文件大小和画面都检查一遍，再放进草稿里，心里更有数。

房间照片原本很大，设置较小的最大宽度后更适合放进房源资料。图片比例保持不变，下载前也能看到最终文件大小。

压缩带小字的 JPG 时，我会先选“保留更多细节”。有了清楚的档位名称更容易决定，处理后我还是会检查文字再使用。

准备发到群里的照片，我试了“更小文件”档位。一边看节省了多少空间，一边看预览，更容易判断细节变柔和之后是否还能接受。

商品照片可以先试一个压缩档位，对比之后再保存。小文件里还要看清搭扣和刻字，这样检查一下很有必要。

有张照片本来就很小，再压一次并没有更省空间。工具保留了原文件并说明原因，我就知道可以改试缩小宽度。

Frequently asked questions
Are my images uploaded?
Your images are processed in this browser and are not uploaded. Sign-in and export allowance checks do not send your images. Download your results before switching tools, refreshing or closing this page.
Which formats can I use?
Import static JPG, PNG and WebP images. Export PNG for transparency or screenshots, or choose JPG or WebP for photos. Animated images are not supported.
Do I need an account?
You can edit and preview without an account. Sign in for one free export per day shared across combine, split, compress and convert, or subscribe for unlimited local exports. Each single-image download or complete ZIP download counts as one export. Local processing does not use cloud credits.
Will compression always make my file smaller?
Results depend on the image and its original encoding. Choose Smaller file for stronger compression or reduce the dimensions. Keep more detail uses gentler compression, and Balanced is the default for everyday sharing. PNG uses lossless encoding without compression presets. When the same format and dimensions produce no savings, the original file is kept. Compare the actual sizes before downloading; your original file is unchanged.
What happens to transparency and metadata?
PNG and WebP support transparency. JPG replaces transparent areas with the background color you choose. Re-encoded exports apply the displayed orientation and remove original EXIF metadata. When compression keeps the original file because encoding did not make it smaller, its original metadata is retained.
What are the current limits?
Add up to 30 static JPG, PNG or WebP images, with a combined source size of 100 MiB. Each image can be up to 20 MiB and 32 megapixels, with a maximum edge of 16384 pixels. Images are processed one at a time using the same settings. Completed results and ZIP downloads are limited to 256 MiB. Animated images are not supported. Download your results before leaving this page.
