Image Resizer
Resize your images to exact pixel dimensions. Choose from social media presets or enter custom width and height. Lock aspect ratio to prevent distortion.
How to use Image Resizer
Steps
- Upload the image you want to resize.
- Enter exact width and height values or use a common preset.
- Keep aspect ratio locked unless you intentionally need to stretch the image.
- Export the resized image in the format that matches your target platform.
Example use case
A 4000 px wide camera photo can be resized to 1600 px for a blog article, reducing page weight while keeping enough resolution for high-density screens.
Settings explained
- Width and height define the exported pixel dimensions.
- Aspect ratio lock prevents faces, logos, and product photos from being distorted.
- Format and quality settings control the final download size after resizing.
Limitations
- Upscaling a small image cannot add real detail.
- Tiny text or thin lines may become less readable after aggressive downsizing.
- Browser memory can limit extremely large source images.
Troubleshooting
- If the image looks stretched, turn aspect ratio lock back on.
- If the image is soft, resize from the original file instead of a previously compressed version.
- If the export is too large, combine resizing with WebP or JPG compression.
