Photo Filters — frequently asked questions

What does 100% mean?+

For brightness, contrast and saturation, 100% is unchanged; below darkens/flattens, above boosts. For grayscale/sepia/invert, 100% is full effect.

Does it change the file format?+

No — it keeps the input format.

你们会把我的文件上传到服务器吗？+

不会——这里的每个工具都完全在你的设备上处理文件，不会向服务器上传任何内容。唯一的例外是 AI 工具，它们会把提取的文本（而非文件本身）发送给 Claude 来完成工作。

有文件大小限制吗？+

我们没有人为设置限制，但由于处理过程在你的浏览器中进行，非常大的文件（超过 500MB 或 1000 页）会受到你设备内存的限制，而非我们的限制。
