Freeform vs Fixed Ratio

Freeform cropping lets you drag any rectangle. Fixed ratio cropping locks the selection to a specific proportion: 1:1 for profile pictures, 16:9 for video thumbnails, 4:3 for presentations, 9:16 for Instagram Stories. The Image Cropper supports custom ratios too — enter any width:height proportion and the selection snaps to it.

Common Crop Presets

Profile photos: 1:1 square (500×500 or 1000×1000). Social media posts: 1:1 (Instagram), 16:9 (Twitter/LinkedIn), 4:5 (Instagram portrait). Video thumbnails: 16:9 (YouTube), 1:1 (TikTok). Print: 4×6, 5×7, 8×10 inches at 300 DPI. The tool includes presets for all common platforms.

💡 Tip

Use 3+ color stops instead of 2 to avoid the muddy gray band that appears in the center of complementary-color gradients.

Pixel-Perfect Cropping

For exact dimensions, enter pixel values for X offset, Y offset, width, and height. This is essential for sprite sheets, icon extraction, and precise content isolation. The Image Cropper shows a live preview of the cropped area and the output dimensions before you commit.

⚠ Warning

CSS gradients used as backgrounds cannot be animated with standard transitions. Use background-size animation or @property registered custom properties instead.
