# Resize Images to Any Size

Change the width and height of photos and graphics: exact pixels, a percentage, or ready-made sizes. Crop to fill or fit the whole picture. Works on many images at once.

**Quick answer:** To resize an image, add one or more pictures and enter a width, height or percentage, or pick a ready-made size; keep proportions on to avoid stretching. All images get the same settings, can be downloaded as a ZIP and are never uploaded.

## How to use it

1. Choose one or more images.
2. Pick how to resize: preset size, pixels or percentage.
3. For a different shape, choose crop to fill or fit with a background.
4. Press Resize images, then download or send them.

## Three ways to set the size

- **Pixels**: type a width, a height or both. With _Keep proportions_ on, the image is scaled to fit inside the size you give without distortion; leave one box empty to size it automatically.
- **Percentage**: 50% halves the width and height, which cuts the pixel count (and usually the file size) to about a quarter.
- **Preset size**: common sizes such as Full HD 1920 × 1080, square 1080 × 1080 or A4 at 150 dpi.

## When the shape changes: crop, fit or stretch

Resizing a 4:3 photo to a 16:9 or square size means the shapes do not match. You choose what happens:

- **Crop to fill** fills the whole frame and trims the edges, keeping the centre.
- **Fit, blurred background** shows the whole photo and fills the gaps with a soft, blurred copy of it, the look you see on social media.
- **Fit, plain background** shows the whole photo on white.
- **Stretch** forces the image into the frame; people will look squashed, so use it only for textures and patterns.

## Quality matters when shrinking

Big reductions are done in several halving steps with high-quality smoothing, which avoids the jagged edges and shimmering patterns quick resizers produce. Enlarging is possible too, but cannot add detail: a small image scaled up will look soft.

Resized images are saved in their original format unless you choose another, and location data is not copied into the result.

## Frequently asked questions

### How do I resize an image without distorting it?

Keep “Keep proportions” on and enter a width or height, or use a preset with Crop to fill or one of the Fit options.

### Can I resize many images at once?

Yes. All images get the same settings, and you can download them as a ZIP.

### Will resizing reduce the file size?

Making an image smaller in pixels almost always makes the file smaller too, often dramatically.

### Are my photos uploaded?

No. They are resized in your browser on your device.
