Common Resizing Use Cases

Image resizing is essential for preparing photos for website upload to meet size requirements, reducing file sizes by lowering resolution, creating thumbnails for galleries, fitting images into specific layouts or templates, preparing images for email without exceeding attachment limits, and generating multiple sizes for responsive web design.

Scaling Algorithms

We offer three quality levels for resizing: High Quality uses advanced bicubic interpolation for the best results, Balanced provides good quality with faster processing, and Fast mode uses bilinear scaling for quick results. Choose the algorithm based on your needs for quality versus speed.
