Detailed Explanation
Resizing changes an image's pixel dimensions, which is useful for meeting a platform's upload requirements or reducing file size for faster loading. With "Maintain aspect ratio" on, the image is scaled proportionally to fit within your chosen width and height without stretching or distortion.
Frequently Asked Questions
Will resizing distort my image?
Not if 'Maintain aspect ratio' is checked — the image is scaled proportionally. Unchecking it stretches the image to exactly match the width and height you enter, which can distort it if the ratio does not match the original.
Are the preset sizes exact requirements?
Presets use commonly recommended dimensions for each platform. Always double check the current official requirements for critical use cases like passport photos.
