局限性

While image resizers are valuable tools, they do have some limitations. Here are a few to consider:

2. 寬高比:

Changing the aspect ratio of an image can lead to distortion, mainly if you are resizing it disproportionately. To avoid distortion, maintain the aspect ratio when resizing the image.

3. 解析度:

 Resizing an image can affect its solution, which can be important for print materials. Make sure to use an image resizer to specify the DPI and resolution.

4. 相容性:

Some image resizers may only support some image formats or be compatible with all devices or platforms.

3. Before using, you should read the terms and policies of the image resizer to learn how your data will be used and stored.

5. Delete any resized or original images you no longer need to reduce the risk of unauthorized access.
