Free Image Aspect Ratio Changer
Whether you are designing a YouTube thumbnail, uploading a perfectly square Instagram post, or formatting professional photography for print, using the correct aspect ratio is crucial. Our free Image Aspect Ratio Changer is a professional browser-based utility that allows you to crop, pad, and resize your photos to exact geometric proportions instantly without losing visual quality.
How to Change Aspect Ratios
- Upload Your Photo: Drag and drop your JPG, PNG, or WebP file into the upload zone. The tool will instantly load a live preview workspace.
- Select Your Ratio: Choose from industry-standard presets like 16:9 (Widescreen), 1:1 (Square), and 9:16 (Vertical Video). Need a specific size? Select "Custom Ratio" and enter your exact X and Y proportions.
- Choose Resize Mode:
- Crop to Fill: This mode fills the entire new canvas. If your original image doesn't match the new ratio perfectly, the edges will be elegantly cropped to prioritize the center subject.
- Pad to Fit: Want to keep the entire image without cutting anything off? Pad mode shrinks your image to fit inside the new ratio and adds a customizable border (background color) to fill the empty space.
- Download: Once the live preview looks perfect, click "Download Image" to save the high-resolution file directly to your device.
