Image Resize
Resize images to your desired dimensions. Supports aspect ratio preservation and format conversion.
Image Resize Guide
Image resizing is needed in various situations like web optimization, SNS uploads, and thumbnail creation. Maintaining the original aspect ratio while reducing size ensures the image shrinks naturally without distortion.
Unlocking aspect ratio lock allows independent width/height settings, but resizing to a different ratio may stretch or squish the image.
