Custom ratio image scaling is an image processing technique used to fill images according to user-specified proportions to meet specific size requirements. This technique adds extra pixels to fill the image, maintaining the desired ratio while minimizing distortion or cropping of the image content.

Using custom ratio filling technology, users can adjust the size of images based on specific application needs without causing deformation or stretching of the image content. This is very useful for displaying images in scenarios such as web design, graphic design, and social media posts.

Through custom ratio filling, users can achieve the following main functions:

1. Maintain image content integrity: The filling technique ensures that the main content and details of the image are preserved, avoiding distortion or cropping due to size adjustment.

2. Adapt to different size requirements: Users can customize the filling ratio according to the needs of different platforms, devices, or media, allowing images to perfectly fit the required dimensions.

3. Avoid image deformation: Compared to simply stretching the image, custom ratio filling maintains the original aspect ratio of the image, avoiding deformation and distortion of the image content.

4. Creative design and layout: Filling technology can also be used to create unique design effects, such as using image filling in web design to create tiled backgrounds or visual elements, enhancing the appeal and creativity of the design.

In summary, custom ratio filling is a useful image processing technique that allows users to adjust the size of images to fit different application scenarios without altering the image content. This technique provides designers and creatives with more flexibility and control, enabling them to better display and present images.

The operation is also very simple. Upload 1 image, freely adjust the size of the expanded areas on the top, bottom, left, and right, and other built-in parameters are preset. Just run it with one click.
