Websites, marketplaces, and social platforms often require specific image dimensions. Uploading the wrong size results in awkward cropping, stretched images, or outright rejection.
Common Size Requirements
| Platform | Recommended Size |
|---|---|
| Instagram post | 1080×1080 px |
| Instagram story | 1080×1920 px |
| Facebook cover | 820×312 px |
| YouTube thumbnail | 1280×720 px |
| Blog featured image | 1200×630 px |
| Product photo (marketplace) | 800×800 to 1200×1200 px |
| LinkedIn banner | 1584×396 px |
How to Resize
- Open Image Resize.
- Upload your image (JPG, PNG, or WebP).
- Enter the target width and height.
- Enable "Lock aspect ratio" if you want proportional scaling.
- Choose output format if needed.
- Download the resized image.
Resize by Percentage
If you just need to make an image smaller without a specific pixel target:
- 50% reduces the image to half its dimensions
- 25% creates a thumbnail-sized version
After Resizing
- If the file is still too large, use Image Compress to reduce the file size.
- If you need a different format (e.g., PNG to JPG), use Image Converter.
Quality Tips
- Enlarging a small image (e.g., 300px to 1200px) will look blurry. Always start with the largest source image available.
- For web use, JPG at 80–85% quality offers the best balance of size and appearance.
- Resize first, then compress. This order gives better results than compressing first.
