AI 生成式填充：替换任意选区

几乎总是三件事之一。文件超过 20 MB 免费上传限制 - Premium 需要 50 MB，Pro 需要 120 MB。该工具不接受该格式，因此请检查上传面板上显示的列表。或者该文件实际上并不是其名称所示的格式：重命名文件不会更改其中的内容，这就是看起来有效的图像被拒绝的原因。

Start with a sharp original and select the intended preset. Use Custom instructions to name the change and the details to preserve. If necessary, open Refine area manually and adjust the editable area. Regenerate, then compare the subject, labels, edges and surrounding detail against the source before using the result.

AI Generative Fill supports free standard use within the published processing allowances. Free downloads are clean — no watermark. No signup is required for standard tool use. Photo effects and AI edits have a web-size limit on Free, with the original-resolution result available through Premium or one credit. Crop, resize, rotate, compress and convert stay full size. Published processing allowances and file limits still apply.

否 — AI Generative Fill 在桌面和手机上的浏览器中运行。在您看到它是否满足您的需要之前，无需安装任何东西，无需试用，也无需购买许可证。在您实际遇到的文件而不是样本上尝试一下。
