How the Image Cropper Works
Cropping removes the outer portions of an image to focus on the subject or fit a specific aspect ratio. Unlike resizing (which changes the pixel count), cropping cuts away unwanted areas while keeping the remaining content at its original resolution.
This tool shows your image with a draggable crop box. Position it over the area you want to keep, adjust the dimensions, then download the result as a full-resolution PNG. Everything happens in your browser using the Canvas API — your image is never uploaded anywhere.
Social Media Image Sizes
Every platform has different size requirements. Crop to these dimensions for the best display:
| Platform | Use Case | Dimensions | Aspect Ratio |
|---|---|---|---|
| Square post | 1080 × 1080 | 1:1 | |
| Portrait post | 1080 × 1350 | 4:5 | |
| Story / Reel | 1080 × 1920 | 9:16 | |
| YouTube | Thumbnail | 1280 × 720 | 16:9 |
| Twitter/X | Image post | 1200 × 675 | 16:9 |
| Post image | 1200 × 627 | 1.91:1 | |
| Post image | 1200 × 630 | 1.91:1 | |
| Cover photo | 820 × 312 | 2.63:1 |
Tip: Crop to the right aspect ratio here, then use Image Resizer to hit the exact pixel dimensions if needed.
Crop vs Resize: When to Use Each
Crop when...
- Removing unwanted edges or background
- Focusing on a specific subject
- Changing the aspect ratio (landscape to square)
- Cutting out distracting elements
Resize when...
- Keeping all content but changing dimensions
- Making images smaller for web/email
- Scaling up for print
- Hitting exact pixel requirements
Need both? Always crop first, then resize. Cropping after resizing means you're working with fewer pixels and lower quality.
Common Aspect Ratios
1:1
Square. Instagram, profile pictures, app icons.
4:3
Classic photo. Digital cameras, PowerPoint.
3:2
DSLR photos. Standard print sizes (6×4).
16:9
Widescreen. YouTube, presentations, TV.
4:5
Instagram portrait. Maximum feed real estate.
9:16
Vertical video. Stories, Reels, TikTok.

Sizes in pixels. Always crop to the recommended dimensions before uploading — platforms will compress and re-crop your image if it doesn't match, often with ugly results. For profile photos, keep the important content centred since platforms display them as circles.
