About this tool
WRRK's image cropper trims your image to an exact pixel size for a specific platform — Instagram, Facebook, LinkedIn, Twitter, YouTube, Pinterest — using auto center-crop. The cropping math runs locally in your browser using the Canvas API so your photos never leave your device.
Each social media platform has different ideal dimensions. Instagram square posts are 1080×1080, Stories and Reels are 1080×1920, Facebook covers are 851×315, LinkedIn banners are 1584×396, Twitter headers are 1500×500, and YouTube thumbnails are 1280×720. Uploading a mismatched size means the platform crops it for you — usually poorly. Cropping it correctly first means your subject stays centered and visible.
How to crop an image (5 steps)
- Drop your image. Drag a JPG, PNG, or WebP into the drop zone, or click 'Choose image' to browse. The crop preview loads instantly.
- Pick a preset. Choose Instagram Square, Story, Facebook Cover, LinkedIn Banner, Twitter Header, YouTube Thumbnail, Pinterest Pin — or click 'Custom' to enter your own width × height.
- Pick output format. PNG keeps transparency and is lossless. JPG is much smaller for photos — pick a quality between 85-95% for social uploads.
- Crop. Click 'Crop image'. The center of your photo is kept, longest dimension is trimmed to match the target aspect ratio, and the result is scaled to exact pixels.
- Download. Click 'Download' to save the cropped image. Filename includes the dimensions so you can keep track of multiple crops of the same source.

Frequently asked questions
+−What's the right size for an Instagram post?
Square posts: 1080×1080 px. Portrait posts: 1080×1350 px (4:5 aspect ratio — gives you the most feed real estate). Stories and Reels: 1080×1920 px (9:16). Use the Instagram Square or Instagram Portrait preset and the crop happens automatically.
+−Does this cropper upload my photo to a server?
No. Cropping runs entirely in your browser using the Canvas API. Your image is never uploaded — the tool works offline once the page has loaded, and we never see or store your files.
+−How does the auto center-crop work?
The tool centers your image, then crops the longest dimension to match the target aspect ratio. For example, a 4000×3000 photo cropped to 1080×1080 keeps the middle 3000×3000 region, then resizes that to 1080×1080. The most important content is usually centered, so this works for most photos.
+−Should I export as PNG or JPG?
Use JPG for photos — files are 5-10× smaller at near-identical visible quality. Use PNG for screenshots, logos, graphics with sharp text, or anything with transparency. JPG quality 90-95% is a great default for social media uploads.
+−What's the recommended YouTube thumbnail size?
1280×720 pixels (16:9 aspect ratio) is YouTube's recommended size — it's the minimum required for HD playback and matches YouTube's player aspect ratio. Files must be under 2 MB. The YouTube Thumbnail preset crops to this exact size.
+−Can I use a custom width and height?
Yes. Click the 'Custom' button and enter any width × height in pixels. The tool will center-crop your image to match that aspect ratio, then scale to your exact dimensions.
+−Why does my JPG export have a white background instead of transparent?
JPG doesn't support transparency. If your source image has transparent pixels (common in PNG logos), they're filled with white when you export to JPG. Use the PNG output option to preserve transparency.
