FREQUENTLY ASKED QUESTIONS

Q: Will resizing make my image look blurry?

Scaling down preserves extreme sharpness. Scaling up beyond original bounds may interpolate pixels.

Q: How do I resize by exact percentage?

Our simple interface includes a toggle switch allowing you to transition from pixel dimensions to scale percentage.

Q: Does it support batch resizing?

Currently, images are resized individually to ensure you can adjust custom crop or ratio constraints for each photo.

Q: What is the "Lock Aspect Ratio" feature?

When locked, changing the width automatically adjusts the height proportionally to prevent stretching or squeezing.
