How to Resize Images Without Distorting Them

Resizing changes how many pixels an image has. Done carefully, it keeps proportions looking natural. Done poorly, faces stretch and logos look skewed. Distortion usually comes from unlocking aspect ratio without intending to.

Maintain aspect ratio

Aspect ratio is the relationship between width and height (for example 4:3 or 16:9). When you change width with “maintain aspect ratio” on, height follows automatically. That is the default you want for most photos.

Width, height, and max edge

• Exact width × height with ratio locked → fits inside the box without stretching.
• Max width / max height → caps one side; smaller images stay unchanged unless you allow upscaling.
• Percentage → scales both sides together.

Avoid unwanted upscaling

Enlarging a small photo beyond its original pixels invents detail and often looks soft. Keep “allow upscaling” off unless you knowingly need a larger canvas.

Cropping versus resizing

Crop when you need a new frame (square social crop, 16:9 hero). Resize when you need fewer pixels at the same composition. Use Crop Image for framing, then resize if the crop is still larger than required.

Batch resizing

For many photos of different sizes, max-width mode is often safer than forcing every file to the same exact dimensions. Each image keeps its own aspect ratio and is not enlarged past its original size by default.

1. Add the batch of images.
2. Choose max width (for example 1200 px) or custom dimensions with ratio locked.
3. Pick an output format such as WebP.
4. Convert and download individually or as a ZIP.
