Image Resizer Tool

Image resizing is the process of changing the dimensions (width and height) of an image. This can be done to reduce file size, fit specific display requirements, or optimize images for web use.

Our tool offers two resize modes:

• Exact Dimensions - Set specific width and height in pixels
• Scale by Percentage - Resize by a percentage of the original size

Both modes can maintain aspect ratio to prevent image distortion.

Aspect ratio is the proportional relationship between an image's width and height. Maintaining aspect ratio ensures your image doesn't appear stretched or distorted when resized.

• 16:9 - Widescreen format (1920×1080)
• 4:3 - Traditional format (1024×768)
• 1:1 - Square format (800×800)

Our image resizer supports all common image formats:

• JPG/JPEG - Most common web format
• PNG - Supports transparency
• WebP - Modern efficient format
• GIF - Animated images (becomes static when resized)
• BMP - Windows bitmap format

Common scenarios for image resizing:

• Web optimization - Reduce loading times
• Social media - Match platform requirements
• Email - Reduce attachment sizes
• Print - Match paper dimensions
• Mobile apps - Optimize for different screen sizes
• Thumbnails - Create smaller preview images

Our tool uses high-quality algorithms to maintain image clarity:

• Downscaling (making smaller) - Usually maintains good quality
• Upscaling (making larger) - May reduce sharpness
• Best practice - Keep original images large and resize down as needed
• Quality setting - We use 95% quality to preserve detail
