Image Cropper

Image cropping selects and extracts a rectangular region from a larger image, discarding the surrounding areas. Our online cropper uses HTML5 Canvas API to manipulate images directly in your browser. When you upload an image, it's loaded into a canvas element where you can define crop boundaries using an interactive selection tool. You can either freehand select any rectangular area or constrain proportions to common aspect ratios (1:1 for squares, 16:9 for widescreen, 4:3 for standard, etc.). The cropper calculates pixel coordinates for the selected region, then extracts and renders those pixels into a new image. Advanced features include zoom controls for precise pixel-level cropping, rotation before cropping, and the ability to maintain original image quality or compress for web use. The entire process happens client-side using JavaScript - your images never leave your device, ensuring privacy. The final cropped image can be downloaded in various formats (PNG, JPEG, WebP) with customizable quality settings.

1. Social Media Content
Crop images to exact dimensions required by different platforms: Instagram (1:1 square, 4:5 portrait, 1.91:1 landscape), Facebook (1.91:1 cover, 1:1 profile), Twitter (2:1 header, 1:1 profile), LinkedIn (4:1 cover). Each platform has specific size requirements, and proper cropping ensures your images display correctly without awkward automatic cropping.

2. Profile Pictures & Avatars
Create square profile pictures from portrait or landscape photos. Crop to focus on faces, centering subjects for optimal visibility at small sizes. Remove unwanted background elements or other people from photos to create clean, professional profile images.

3. Product Photography & E-commerce
Crop product images to consistent aspect ratios for online stores, ensuring uniform appearance across product catalogs. Remove distracting backgrounds, focus on product details, and create consistent white-background images for professional listings.

4. Document Scanning & Cleanup
Crop scanned documents to remove scanner bed edges, straighten tilted scans, and focus on document content. Extract specific sections from multi-page scans, crop receipts for expense reports, or isolate signatures and stamps from documents.

5. Photo Editing & Composition
Improve photo composition by applying the rule of thirds, remove unwanted elements from edges, change orientation (landscape to portrait), and create multiple crops from a single photo for different uses (print, web, mobile).

• Use aspect ratio constraints to crop for specific platforms or print sizes without distortion

• Apply the rule of thirds for better composition - position subjects at intersection points

• Leave breathing room around subjects - don't crop too tightly, especially for faces

• Crop at the highest resolution possible, then resize down to prevent quality loss

• For print photos, maintain aspect ratios that match standard frame sizes (4:6, 5:7, 8:10)

• When cropping portraits, avoid cutting at natural joints (neck, wrists, knees)

• Use zoom to make precise crops and verify you're not cutting off important details

• Save originals before cropping - crop operations are destructive and can't be undone after download
