Resize by pixels, percentage, or choose from hundreds of preset dimensions for social media, web, and print.
Automatically maintain proportions or freely adjust dimensions with our intelligent aspect ratio controls.
Upload and resize multiple images simultaneously, applying the same dimensions to your entire photo collection.
Advanced algorithms ensure your resized images maintain exceptional clarity and color accuracy.
Perfect your Instagram posts, Facebook covers, Twitter headers, and LinkedIn banners with platform-optimized dimensions.
Optimize images for faster website loading while maintaining visual quality across all devices and screen sizes.
Prepare images for business cards, flyers, posters, and professional prints with precise DPI and dimension control.
Resizing by pixels lets you set exact dimensions (e.g., 1920x1080 for HD), perfect when you need specific sizes. Percentage resizing scales proportionally (e.g., 50% makes the image half the size), ideal for uniform scaling while maintaining the original aspect ratio.
Our tool uses advanced resampling algorithms to preserve quality. When enlarging images, avoid going beyond 150% of original size. When reducing, maintain aspect ratios and use our smart compression settings. For best results, start with high-resolution originals.
Popular sizes include: Instagram posts (1080x1080), Facebook cover (1200x630), Twitter header (1500x500), LinkedIn banner (1584x396), and YouTube thumbnail (1280x720). Our preset options include optimized dimensions for all major social platforms.
Generally yes, to prevent distortion. Locked aspect ratio maintains proportional scaling, keeping your images looking natural. Unlock only when you specifically need different proportions or are creating graphics that require exact custom dimensions.
Absolutely! For print, ensure at least 300 DPI resolution. Common print sizes: 4x6 (1200x1800 pixels), 5x7 (1500x2100), 8x10 (2400x3000), and 11x14 (3300x4200). Our presets include standard print dimensions with optimal DPI settings.
Our resizer supports all major formats: JPEG, PNG, WebP, HEIC, GIF, and BMP. The output format can match your input or be converted during resize. PNG preserves transparency, JPEG offers smaller file sizes, and WebP provides the best compression for web use.
