Three ways to resize
- Width only — e.g. 1200 px; the height follows the original proportions.
- Width and height — the image fits inside the box without distortion (untick "Keep aspect ratio" to force exact dimensions).
- Percentage — e.g. 50 % halves both sides.
Common sizes
| Use | Size |

| Website hero / full-width | 1920 px wide |
| Blog content image | 1200 px wide |
| Open Graph / link preview | 1200 × 630 |
| Instagram post | 1080 × 1080 or 1080 × 1350 |
| YouTube thumbnail | 1280 × 720 |
Resizing uses high-quality smoothing. To change the shape of the image, use the Image Cropper; to reduce file size further, run the result through the Image Compressor.
Frequently asked questions
Can I make a small image bigger?
Yes, but enlarging cannot add detail, so the result may look soft.
Can I resize many images at once?
Yes, select several files and download them all as a ZIP.
Are my images uploaded?
No, resizing runs in your browser.
