How does aspect ratio locking work?
When aspect ratio is locked, changing either width or height automatically updates the other dimension to prevent stretching or distortion.

Frequently Asked Questions
Can I resize a batch of multiple images together?
Yes. You can scale an entire batch by percentage (e.g. 50% smaller) or to a common maximum bounding box.
Does resizing degrade image clarity?
IMGUtils uses multi-pass bicubic canvas resampling to retain maximum edge sharpness and minimize downsampling moire.
