Frequently Asked Questions
An aspect ratio is the proportional relationship between an image's width and height. For example, 16:9 means the width is 16 units for every 9 units of height. Common ratios include 1:1 (square), 4:3 (standard photo), 16:9 (widescreen), and 3:2 (classic print).
It depends on the platform. Instagram posts use 1:1 (square) or 4:5 (portrait). Instagram Stories and TikTok use 9:16 (vertical). YouTube thumbnails use 16:9 (widescreen). Facebook posts work best at roughly 1.91:1 (1200x630). Twitter/X headers use 3:1 (1500x500).
Upload your image, then enter your desired Width and Height values in the input fields above the crop area. Click "Apply" to lock the crop box to that ratio. For example, entering Width 16 and Height 9 locks the crop to 16:9. You can then drag and resize the box while maintaining the ratio.
Standard print sizes use these ratios: 4x6 prints are 3:2, 5x7 prints are 7:5, 8x10 prints are 5:4, and 11x14 prints are roughly 7:5. For borderless printing, crop your photo to the exact ratio of your target print size to avoid unexpected trimming.
No. Cropping to a different aspect ratio simply trims the edges of your photo. The remaining pixels stay at their original quality and resolution. No compression or resampling is applied during the crop.
Aspect ratio describes the shape of an image (e.g., 16:9 is widescreen), while resolution describes the total number of pixels (e.g., 1920x1080). Two images can share the same 16:9 ratio but have different resolutions like 1280x720 or 3840x2160.
