What is Perspective Crop?
Perspective Crop is a free online tool to fix distorted images and documents. When you take photos of documents, whiteboards, or business cards at an angle, they appear skewed. This tool lets you straighten them by adjusting four corner points. The perspective transformation corrects the distortion, giving you a perfect rectangular image as if it was scanned flat.
How to Fix Perspective
Upload your skewed image and you'll see four draggable corner points on the image. Drag each point to match the corners of the document or object you want to straighten. As you adjust the points, the preview updates in real-time showing the corrected perspective. Once satisfied, choose your output size and format, then download the straightened image.
Common Uses
Perfect for digitizing documents without a scanner. Take a photo of receipts, contracts, notes, or business cards at any angle and straighten them into professional-looking scans. Great for whiteboard photos after meetings - capture brainstorming sessions and presentations, then correct the perspective. Architectural photographers use it to fix converging lines in building photos. Students digitize textbook pages and homework. Real estate agents straighten room photos.
Tips for Best Results
Take photos from directly above when possible to minimize distortion. Ensure good lighting and avoid shadows on the document. Place corner points precisely at document corners for accurate correction. For documents with text, use PNG format to maintain crisp edges. JPEG works well for photos. Choose "Original Size" to keep maximum quality, or select a smaller size for easier sharing and faster uploads.
