Maintaining Aspect Ratio
Aspect ratio is the proportional relationship between width and height. When enabled, changing one dimension automatically adjusts the other to prevent image distortion.
Lock aspect ratio (default): Enter either width or height, and the other dimension calculates automatically. Your image won't stretch or squash.
Unlock aspect ratio: Enter exact dimensions for both width and height. Use this when you need specific dimensions and plan to crop.
Common aspect ratios include:
- 1:1 - Square format
- 4:3 - Traditional photo format
- 16:9 - Widescreen, video format
- 3:2 - DSLR photo format
- 9:16 - Vertical video (Stories, Reels)
Batch Resizing
Process multiple images at once with consistent dimensions:
- Upload multiple images by dragging them into the tool
- Choose your target dimensions or preset
- Select a resize mode (fit, fill, or stretch)
- Process all images and download as a ZIP
Resize Modes Explained
- Fit - Scales the image to fit within the target dimensions while maintaining aspect ratio. May result in letterboxing.
- Fill - Scales and crops the image to completely fill the target dimensions. Some content may be cropped.
- Stretch - Forces the image to exactly match target dimensions. May distort the image.
Quality Settings
Resizing affects image quality, especially when enlarging. Here's how to get the best results:
- Downscaling - Generally safe. Images remain sharp when reduced. Use "high quality" resampling for best results.
- Upscaling - Can cause blurriness. Avoid enlarging more than 150-200% of original size. Consider AI upscaling tools for larger increases.
- Resampling method - We use Lanczos resampling by default, which provides the best quality for both up and downscaling.
After resizing, consider using our compression tool to optimize file size while maintaining your newly sized image's quality.
