When to use this
You took a great group photo but one edge has a stranger walking through the frame. Or you need to turn a landscape shot into a square for your Instagram feed without the platform deciding what gets cut. Maybe you're preparing headshots for a team page and every image needs to be the same 1:1 square with the face centered. Cropping is about choosing what stays in the frame — and just as importantly, what doesn't.
Unlike resizing, which scales the entire image up or down, cropping removes content from the edges. A 4000 x 3000 photo cropped to 16:9 becomes 4000 x 2250 — the sides stay sharp, but the top and bottom are gone. This makes cropping the right tool when you need to recompose a shot, eliminate distractions, or fit an image into a specific aspect ratio for a platform or layout.
The circle crop option is specifically for profile pictures. Facebook, LinkedIn, Twitter, and Google all display avatars as circles. Rather than uploading a square and hoping the platform's cropper centers your face correctly, crop it yourself with a circular mask that exports as a PNG with transparent corners. You control exactly what appears inside the circle.
Good to know
Freeform crop gives you total control. When no aspect ratio is locked, you can drag the crop box to any rectangular shape. This is useful for cutting out a specific section of a screenshot, removing a watermark area, or isolating a region of interest from a larger image.
Locking an aspect ratio prevents accidental distortion. When you set 16:9, the crop box can only be resized proportionally. This guarantees the output fits perfectly into a YouTube thumbnail, presentation slide, or widescreen banner without letterboxing.
Circle crop outputs a PNG, not a JPG. JPEG doesn't support transparency, so the circular mask requires PNG format. If the original was a JPG, the cropped output will be a PNG file — slightly larger, but with clean transparent corners instead of white or black fill.
Crop before you resize. Cropping first means you're working with the full-resolution original. If you resize down first and then crop, you're throwing away pixels you already paid for. The optimal workflow is crop, then resize to your target dimensions.
All processing happens in your browser. Your images are drawn to an HTML5 Canvas element and cropped locally. No pixel data leaves your device at any point.
