How to Crop Images Online
SmarterSources' image cropper lets you cut any image to the exact dimensions you need, directly in your browser. Whether you're preparing photos for social media, trimming screenshots, or cutting out specific parts of an image, this tool makes it instant and easy.
Interactive Crop Selection
Drag anywhere on your image to draw a crop area, then fine-tune it by dragging the edges and corner handles. The rule-of-thirds grid overlay helps you compose your crop for the best visual result. You'll see the exact pixel dimensions updating in real time as you adjust.
Aspect Ratio Presets
Use the preset buttons to lock your crop to common aspect ratios: 1:1 (square, perfect for Instagram and profile photos), 16:9 (widescreen, great for YouTube thumbnails and banners), 4:3 (classic photo ratio), 9:16 (vertical stories and reels), and more. Select "Free" to crop to any custom shape.
Perfect for Social Media
Every social media platform has different image dimension requirements. Use the aspect ratio presets to quickly crop your images for Instagram posts (1:1), Instagram stories (9:16), Facebook covers (16:9), Twitter headers (3:1), LinkedIn banners (4:1), and YouTube thumbnails (16:9).
Privacy First
Your images are cropped entirely within your browser using the HTML5 Canvas API. Nothing is uploaded to any server. Your files stay on your device from start to finish.
Frequently Asked Questions
Does cropping reduce image quality?
No. Cropping simply removes the portions of the image outside the selected area. The remaining pixels are preserved at their original quality. The output file will be smaller in dimensions and file size, but the quality of the cropped area remains identical to the original.
What image formats are supported?
The cropper supports all common image formats: PNG, JPG/JPEG, WebP, GIF, and BMP. The output is saved in the same format as your original image to preserve quality and transparency.
Can I enter exact pixel dimensions?
Yes. Use the width and height input fields below the aspect ratio buttons to see the exact output dimensions. You can also type specific values to set a precise crop area size.
How do I crop a square image for Instagram?
Click the "1:1" aspect ratio button, then drag the crop area to select the portion of your image you want. The selection will always be perfectly square. Click "Crop & Download" to save.
Is there a file size limit?
No artificial limit. Since everything runs in your browser, the only constraint is your device's available memory. Most devices handle images up to 50-100MB without any issues.
