Fixed ratios

1:1, 4:5, 3:2, 16:9, 9:16 and more, or drag freely.

Rotate & straighten

90° steps plus a fine slider for level horizons.

Exact output

Crop an 800 × 800 region and export it at 512 × 512.

Cropping, rotating and straightening

Pick a ratio — free, 1:1, 4:5, 3:2, 4:3, 16:9, 9:16, 21:9 or your own W:H — and drag the frame over the part you want to keep. The circle option locks to a square and saves a PNG, so the corners stay transparent for avatars and logos.

Rotate in 90° steps, flip horizontally or vertically, and use the Straighten slider (±45° in half-degree steps) to level a tilted horizon. Keyboard shortcuts: R and Shift+R rotate, H and V flip, Enter applies and Esc resets.

Turn on “Exact output size” to scale the crop to a precise width and height, such as 1080×1080 for a post. Export as JPG, PNG, WebP or AVIF, copy to the clipboard, or pass the result straight to another tool.

Common questions

Choose the circle option. The frame locks to a square, and the download is a PNG with transparent corners, so it sits cleanly on any background.

Pick the 1:1 ratio, place the frame, then switch on “Exact output size” and enter 1080 × 1080. The crop is scaled to exactly those pixels.

Cropping only removes pixels outside the frame. The saved file is re-encoded; PNG is lossless, and JPG, WebP and AVIF default to quality 92, which is visually identical for most photos.
