小鹿的操作笔记NOTES FROM THE ISLAND
从一个小例子，开始。Start with a small example.
图片太大、PDF 只要几页、表格格式不合适？选一个任务，跟着做，再检查自己的结果。An image is too large. You need just a few PDF pages. A table needs another format. Pick a task, follow the steps, and check your result.

用轻图设置目标大小、选择格式，再核对清晰度。原图保留在你的设备上，处理过程不需要上传文件。Set a size target in Qingtu, choose a format, and check the result. Keep your original on your device; processing does not upload the image.
