Image Cropper
Crop an image with numeric inputs or preset aspect ratios (1:1, 16:9, 4:3, 9:16…).
How to Use
- Drop your image into the input area or click to browse.
- Pick a preset aspect ratio (1:1 square, 16:9 widescreen, 4:3 standard, 3:2 photo, 9:16 portrait, 2:3 portrait) or "Free" for any dimensions.
- Enter the crop box position (X, Y) and size (Width, Height) in pixels.
- Click "Center box" to position the crop in the middle of the image.
- The preview shows the cropped region in real time.
- Click Download to save the cropped image. Original is never uploaded.
Aspect ratios
Frequently Asked Questions
What's the difference between cropping and resizing?
Cropping cuts a rectangular portion out of the image and discards the rest — content is removed but the remaining pixels are unchanged. Resizing scales the entire image to new dimensions while preserving all content. Use crop when you only want part of the image; use resize when you want the whole thing at a different size.
Which aspect ratio should I use?
<strong>1:1</strong> for avatars, profile pictures, Instagram posts. <strong>16:9</strong> for videos, YouTube thumbnails, modern presentations. <strong>4:3</strong> for legacy TV slides and many older photo prints. <strong>3:2</strong> for traditional 35mm and DSLR photo prints. <strong>9:16</strong> for vertical video, Stories, Reels, TikTok. <strong>2:3</strong> for portrait-oriented photo prints (4×6, 8×12 inches).
Will I lose quality by cropping?
No — cropping is lossless. The pixels you keep are bit-for-bit identical to the original. The only loss is from re-encoding (if you save as JPEG/WebP after cropping); save as PNG to preserve every pixel exactly.
How do I crop to standard photo print sizes?
Standard prints have specific aspect ratios: 4×6 = 2:3, 5×7 ≈ 5:7 (no preset), 8×10 = 4:5, 11×14 ≈ 11:14, 16×20 = 4:5. For non-standard ratios, use Free mode and enter exact pixel dimensions: 1500×2100 for 5×7 at 300 DPI, etc.
Can I crop multiple images at once?
This tool handles one image at a time. For batch cropping with the same parameters across many images, you'd want a desktop tool like ImageMagick. Most batch crop scenarios are actually batch resize + crop-to-aspect, which is closer to what social-media-sizer does.
Is the crop box visualized on the original?
Yes — when you enter coordinates, the preview shows the cropped result. For interactive drag-to-crop with handles, see image-rotate-flip and other interactive editors. This tool is precise crop-by-coordinate, optimized for matching exact specifications (passport photos, ID dimensions, social-media sizing).

Crop to platform-specific ratios: Instagram square 1:1 or portrait 4:5, X 16:9, Pinterest 2:3.
Removing unwanted content
Crop out passers-by, distracting backgrounds, or accidental hand at the edge of the frame.
