The tool runs entirely in your browser, and nothing is uploaded. Open the web page above to use it.

## Why use this image resizer?

### Exact sizes for any platform

Hit the dimensions a CMS, app store or social network asks for, down to the pixel.

### Aspect ratio stays locked

Type a width and the height follows, so nothing gets stretched. Unlock it when you really do need a different shape.

### Sharp downscaling

Large reductions are done in steps, which keeps edges and text cleaner than a single resize.

### Nothing is uploaded

Resizing runs in your browser, so the image is processed on your device and never touches a server.

## How to use the image resizer

1. Drop, choose or paste an image.
2. Enter a width or height, or switch to percentage.
3. Check the new size, then download the resized image.

## What does resizing an image do?

Resizing changes how many pixels an image has. Making it smaller reduces file size and load time; making it larger cannot add detail, so upscaled images look softer. For the web, resize to the largest size the image is actually shown at, then compress it.

## Frequently asked questions

### Which formats can I resize?

PNG, JPG and WebP are saved in their original format. Other formats your browser can open, such as GIF or BMP, are saved as PNG.

### Will resizing reduce quality?

Shrinking an image keeps it sharp. Enlarging it spreads the same detail over more pixels, so it will look softer the further you go.

### Is there a size limit?

Browsers cannot create images wider or taller than 16,384 pixels, so the tool stops you before that. Very large photos may also be slow on older devices.

### Are my images private?

Yes. The image is resized in your browser and is never uploaded.
