FAQ

What aspect ratios does the image cropper support?
It offers 1:1 square, 4:3, 3:4, 16:9, 9:16 and free crop, covering avatars, cover images, social feeds, blog headers and video thumbnails. Pick a ratio and drag the crop box to compose.
How do I crop an image to 1:1 square for an avatar?
Upload, select the "1:1" preset, drag the crop box over the area you want, then confirm. The square result suits WeChat avatars, Xiaohongshu profiles and e-commerce main images.
Does online cropping reduce image quality?
No. Cropping only changes the frame, not the resolution — output keeps the original quality. If you also need a smaller file, crop first then compress with our compressor.
Can I rotate the image before cropping?
Yes. 90° rotation and horizontal/vertical flip are available before cropping, handy for phone portraits and mis-oriented scans.
Is cropping safe? Is my image uploaded?
Safe. Everything runs locally in your browser; the image never reaches a server, suitable for portraits, documents and design drafts.
Is the result good for Xiaohongshu and WeChat Moments?
Yes. Xiaohongshu prefers 3:4 vertical and 1:1; Moments commonly uses 4:3 and 1:1. These presets are built in, so you can export and post directly.
Do I need to register?
No. Free, unlimited, no watermark — built for bloggers, e-commerce operators and designers with daily cropping needs.
Can I set a fully custom size?
Yes. Choose Free Crop and drag the box edges and corners to any size and position, producing any aspect ratio you need.
