Frequently Asked Questions

How do I crop an image to a specific size in pixels?

Upload your image, then enter the exact width and height in the 'Crop Size (px)' fields and click Apply Size. The crop box updates to those exact dimensions. Then click Crop Image to download.

Can I crop an image to a square (1:1 aspect ratio)?

Yes — click the '1:1' aspect ratio preset button. The crop box will lock to a square shape. Drag it to position the square over the area you want, then click Crop Image.

Does this image cropper upload my photo to a server?

No. All processing happens entirely in your browser using the HTML5 Canvas API. Your image is never sent to any server, making it safe for private, sensitive, or confidential photos.

What image formats can I crop?

You can upload JPEG, PNG, WebP, GIF, and BMP files up to 20 MB. You can download the cropped result as JPEG, PNG, or WebP.

Can I crop an image without losing quality?

Choose PNG as the output format for lossless output — the crop area is exported pixel-for-pixel with no compression artifacts. For JPEG/WebP, set quality to 100% for near-lossless output.

How do I crop a circle from an image?

Use the 1:1 aspect ratio to crop a square first, download as PNG, then use a circle mask in design software or your CSS. The browser Canvas API doesn't support circular exports directly, but a PNG square with 1:1 ratio is the correct starting point.

How do I crop an image for Instagram?

For Instagram feed posts, use the 1:1 preset (square) or 4:5 vertical. For Stories and Reels, use the 9:16 preset. For landscape posts, use 1.91:1 — the closest available preset is 16:9.

Can I rotate the image before cropping?

Yes — click Rotate 90° to rotate clockwise. Each click adds 90°, cycling through 90°, 180°, 270°, and back to 0°. Use Flip H or Flip V to mirror the image horizontally or vertically before cropping.

What is the rule of thirds in image cropping?

The rule of thirds is a composition guideline that divides the frame into a 3×3 grid. Placing the main subject at one of the four grid intersections creates a more visually balanced image than centering the subject. The grid lines overlaid on the crop box show these positions.

What is the best format to save a cropped image?

Use JPEG for photos — it produces the smallest file size. Use PNG for graphics, screenshots, or images with transparency where you need pixel-perfect quality. Use WebP for web images where you want the best quality-to-size ratio and your platform supports it.
