## How to resize an image

1. **Add the image.** A JPG, PNG or WebP. Drop it, paste it or pick it.
2. **Pick a size.** Instagram post, Instagram story, YouTube thumbnail, or Custom with your own width and height.
3. **Download.** Slide between the new size and the original, then save it.

## Resize image for Instagram

Instagram feed posts are 1080 by 1080 pixels and stories are 1080 by 1920. Add your image and pick Instagram post or Instagram story. The image fits inside that box with its proportions kept, so it never looks stretched and nothing gets cut off. To fill the box exactly, start from an image of the same shape: square for a post, 9:16 for a story. A landscape photo picked as a post comes out 1080 pixels wide and shorter than 1080, and Instagram adds no border to it in the feed. The result shows the exact size before you download.

## Resize image for a YouTube thumbnail

YouTube thumbnails are 1280 by 720 pixels, a 16:9 shape. Design or export your thumbnail at 16:9, add it here and pick YouTube thumbnail. It comes out at exactly 1280 by 720 in the same format, ready to upload in YouTube Studio.

## What people use it for

- **Instagram posts at 1080 by 1080.** Pick Instagram post. A square image comes out at exactly 1080 by 1080. A photo of another shape fits inside that box, so crop it square first if you need the exact size.
- **Instagram and TikTok stories at 1080 by 1920.** Pick Instagram story and a 9:16 image from your phone or an editor comes out at 1080 by 1920.
- **YouTube thumbnails at 1280 by 720.** Export your thumbnail at 16:9 at any size, pick YouTube thumbnail, and it comes out at 1280 by 720.
- **Photos for a website or a store.** A 6000 pixel camera photo is wasted in a 1200 pixel column. Pick Custom, type 1200 as the width and pages load faster.

## Questions

### How do I resize an image?

Add the image and pick a size, or pick Custom and type a width and height. The image fits inside that box with its proportions kept and comes back in the same format.

### Can I resize an image to exactly 1080 by 1080?

Yes, if the image is already square. The tool fits the picture inside your size without stretching or cropping, so a 4000 by 3000 photo comes out 1080 by 810. Crop it square first for the exact size.

### Will it stretch or squash my image?

No. Proportions are always kept, and nothing is cropped. The image fits inside the width and height you pick.

### Can I make an image bigger?

No. Enlarging adds blur, not detail, so the tool only makes images smaller. An image already under your size is left as it is.

### Which formats work?

JPG, PNG and WebP. The image comes back in the format it arrived in.

### Does resizing lower the quality?

PNG stays lossless. JPG and WebP are saved again at high quality (92), so the change is hard to see.

### Where does my image go?

Nowhere. It is resized on your device and saved straight from the page.
