Easily Determine Image Aspect Ratios
Instantly calculate aspect ratios for multiple images in bulk. Useful for web design, social media posts, and photo cropping. Just drag and drop your images to find their exact dimensions and ratios — everything stays in your browser.
Upload Images
Upload images to check by dragging and dropping them into the designated area, or by selecting them using the "Select Files" button. Supports major image formats such as JPEG, PNG, GIF, SVG, ICO, and WebP. You can add multiple images at once and upload more later.
Enter Ideal Aspect Ratio (Optional)
Enter the ideal aspect ratio you want to compare, such as "16:9" or "4:3". If you don't enter a value, you can still see the current aspect ratio of each image. When you enter an ideal ratio, the difference between it and the uploaded images is automatically calculated, and rows with large differences are highlighted, allowing you to quickly identify discrepancies.
Check Results & Download
After uploading, a list of each image's "Image Name", "Width (px)", "Height (px)", "Aspect Ratio (e.g., 16:9)", "Aspect Ratio (Decimal)", "Ideal Ratio", "Ideal Ratio (Decimal)", and "Difference" is displayed immediately. In addition, a small thumbnail (preview) of each image is also displayed for visual confirmation. The displayed results can also be downloaded in CSV format (excluding the preview column).
