Image Cropper - Crop Photos Online with Aspect Ratios Free

Crop images precisely by dragging on the canvas

Our Image Cropper lets you trim away everything you don't want from a picture by dragging an interactive crop box directly on top of it. A rule-of-thirds grid and a dimmed overlay help you frame the subject exactly, and corner handles make it easy to resize the selection. All of this happens on an HTML canvas inside your browser, so your images are processed locally and never uploaded to any server.

Cropping is essential for turning a raw photo into something purposeful: centering a subject, removing distracting backgrounds, producing a perfect square for a profile picture, or matching the fixed proportions a platform demands. This tool includes aspect-ratio presets for the most common needs — 1:1, 4:3, 3:4, 16:9, 9:16, 3:2, and 2:3 — that lock the crop box to those proportions as you resize, plus a Free mode for completely custom crops.

Because the crop is taken from the original full-resolution image rather than a scaled-down preview, you never lose quality to unnecessary downscaling, and the live readout shows the exact output dimensions in pixels. The finished crop downloads as a lossless PNG, preserving transparency and detail — ideal for logos, product shots, thumbnails, and any image where fidelity counts.

Frequently asked questions

How do I crop an image online?

Upload an image, then drag the crop box on the canvas to position it. Drag any corner handle to resize the selection, and drag inside the box to move it. When the selection frames what you want, click Download Crop to save the cropped area.

Can I crop to a specific aspect ratio like 1:1 or 16:9?

Yes. Choose a preset such as 1:1 (square), 4:3, 16:9, 3:2 or their vertical variants, and the crop box will lock to that ratio as you resize it. Select Free to crop to any custom proportions instead.

What size is the cropped image?

The output matches the exact pixel region you selected on the original full-resolution image, so no quality is lost from downscaling. The tool shows the crop dimensions live as you adjust the box.

In what format is the crop downloaded?

Cropped images are exported as PNG, which is lossless and preserves transparency. This makes it ideal for logos, product shots, and graphics where you want maximum fidelity.

Are my photos uploaded anywhere when cropping?

No. Cropping is done entirely in your browser with the HTML canvas. Your images stay on your device at all times, so it is safe to crop personal photos and sensitive documents.
