🔍 Why Resize Images?
Image resizing isn't just about making pictures smaller or bigger. It serves critical goals:
- Improves website performance: Large images slow down websites and increase bounce rates.
- Enhances SEO rankings: Google favors fast-loading, optimized content.
- Meets platform-specific standards: Every platform—Instagram, Facebook, Amazon—has specific image size requirements.
- Saves storage and bandwidth: Smaller images mean faster downloads and less space usage.
Whether you're working with JPG, PNG, WebP, or GIF files, the ConvertifyTool Image Resizer supports them all.
⚡ Key Features of ConvertifyTool's Image Resizer
✅ Resize by Pixel Dimensions
You can manually set width and height (e.g., 1200x628 pixels for a Facebook ad). Whether you're resizing a banner for your website or a thumbnail for YouTube, custom control is fully in your hands.
✅ Resize by Percentage
Want to make an image exactly 50% smaller? Just set the percentage value, and the tool handles the math. This is perfect when working with large images that only need slight downsizing.
✅ Aspect Ratio Lock/Unlock
You can choose to maintain the original aspect ratio, ensuring the image doesn't appear squished or stretched. Or unlock it to freely resize.

Skip the guesswork. Choose from presets for:
- Instagram (1080x1080 or 1080x1350)
- Facebook cover (820x312)
