How it works
- Select one or more images.
- Choose dimensions, percentage or a preset.
- Decide whether to keep the aspect ratio.
- Process and download results individually or as a ZIP.
Practical example
The 1200 × 630 preset works as a maximum box for a social image. With aspect ratio enabled, it fits without distortion.
Formula and explanation
In pixel mode, keeping the ratio makes each image fit inside the maximum width and height.
Without the ratio, output uses both dimensions exactly and may look stretched.
Percentage mode applies the same scale to original width and height.
