常见问题
What is an Image Resizer?
An Image Resizer is a tool that adjusts the dimensions (width and height) of an image file. It is used to scale images down for web optimization or scale them up for printing, often while maintaining the aspect ratio to prevent distortion.
What does 'Maintain Aspect Ratio' mean?
Maintaining the aspect ratio ensures that the relationship between the width and height of the image stays constant. When enabled, changing one dimension automatically adjusts the other to prevent the image from looking stretched or squashed.
What is the difference between pixels and percentages?
Pixels are absolute units of measurement (e.g., 1920px wide). Percentages are relative units that resize the image based on its original size (e.g., 50% makes the image half as large as it started).
Will resizing reduce the quality of my image?
Downsizing (making smaller) usually preserves quality, though detail is lost. Upsizing (making larger) often results in pixelation or blurriness because the software has to invent new pixels to fill the space.
Which file formats can I resize?
Common formats like JPEG, PNG, WebP, and BMP are supported. Some advanced formats may require specific tools.
How do I calculate the new file size?
The file size depends on the new pixel dimensions and the compression format. Generally, reducing pixel dimensions by 50% reduces the file size by roughly 75% (since area is width x height).
