Resize Image — frequently asked questions
Will resizing distort my image?+
No — the aspect ratio is preserved. Enter a width and the height is calculated automatically, or scale by a percentage.
Can I enlarge an image?+
You can, but upscaling past the original size cannot add detail — the result will look soft.
What output format do I get?+
The same format as the input (JPG stays JPG, PNG stays PNG, WebP stays WebP).
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。
