Resize proportionally by maximum width, maximum height, or percentage without enlarging the original.

Key Characteristics

Proportional Sizing

Aspect ratio is preserved automatically.

No Upscaling

Smaller images are not enlarged.

Batch Defaults

One rule applies independently to every image.

About This Operation

What to Expect

Resize a batch with one clear rule while each image keeps its own verified source dimensions.

Maximum dimensions reduce only images that exceed the limit. Percentage resize scales each image independently and never enlarges it.

Supported input

Supported still images with authoritative dimensions available before resizing.

Output

Proportional copies constrained by the selected batch rule.

Metadata and Orientation

Metadata removal is the default and does not affect resize geometry.
