Crop Frame Planner

Crop Frame Planner works out where to crop a photo for a target ratio such as 1:1, 4:5, 9:16, 16:9 or 2:3, or any custom ratio. Load a photo or enter its width and height, pick a ratio, then use the two focus sliders to move the crop window left or right and up or down. The tool shows the crop box in whole pixels, the export size at native resolution, and a text-safe box inset from each edge by a percentage you set. You can download the cropped PNG, download a plain-text guide with all the numbers, or print the guide. It runs as a single index.html file in any modern browser. It works offline, makes no network calls and uploads nothing. The file is yours to keep and reuse. Limits: it does not detect subjects, faces or text, and it does not know any platform's current image rules. The text-safe inset is a percentage you choose, not a verified platform requirement, so check each platform's current specifications before posting. PNG export keeps the photo's native resolution and never upscales. Very large photos may be slow to preview. Photo orientation metadata is not corrected. This is a planning and cropping aid, not a design or photo-editing suite.
