Resize an image without stretching it
Image resizing changes the pixel dimensions of a file. When you keep the aspect ratio locked, the image retains its original proportions. If you unlock it and enter unrelated width and height values, the result can look stretched or squashed.
How to use the image resizer
- Select a JPG, PNG or WebP image.
- Choose exact pixel dimensions or scale by percentage.
- Keep aspect ratio enabled unless you deliberately want to distort the image.
- Choose an output format and quality, then export and inspect the downloaded file.
Common image dimensions
| Use | Example dimensions |
|---|---|
| Square graphic | 1080 × 1080 px |
| Landscape image | 1200 × 800 px |
| Vertical social image | 1080 × 1350 px |
| Full HD video thumbnail | 1920 × 1080 px |
These are common working sizes, not universal requirements. Check the destination platform's current specifications when exact compliance matters.
Frequently asked questions
Will resizing make an image sharper?
No. Enlarging adds pixels through resampling but does not restore missing detail. Reducing dimensions can help files load faster.
What format should I export?
JPG is useful for photos, PNG for graphics that need lossless output, and WebP can provide a smaller web-friendly file. Format support depends on the browser.
Are my files uploaded?
No. This tool reads and exports images using your browser's local file and canvas APIs.
