How Smart Center-Crop Works
When your image has a different aspect ratio than the target social media size, our tool uses smart center-crop to create the best result. It scales your image so it fully covers the target area, then crops equally from both sides (or top and bottom) to center the subject.
This approach works well for most photos because the subject is usually near the center. It avoids stretching or adding letterbox bars, giving you a clean, professional result every time.
Frequently Asked Questions
- Will my image be cropped or stretched?
- Your image is never stretched. If the aspect ratio does not match, the tool center-crops the image to fit the target dimensions. It scales the image to cover the full area, then trims the excess from the edges.
- Can I resize for multiple platforms at once?
- You can upload your image once and click through different presets to generate and download versions for each platform. Each click instantly generates the resized preview.
- What format are the downloaded images?
- All resized images are exported as JPEG files at 92% quality, which provides an excellent balance of visual quality and file size suitable for social media uploads.
- Do you store or upload my images?
- No. Your images never leave your device. All resizing is performed locally in your web browser using JavaScript. We do not upload, store, or have access to any of your images.
