Batch Image Resizer

1. Batch Image Resizer

Professional Image Resize Tool for Windows with intelligent resizing algorithms, batch processing, and advanced output control. Process hundreds of images with precision and maintain optimal quality.

1. Ready-to-Use Windows Application

• No installation required: Simply unzip and launch — portable app with all dependencies included.

1. What This Application Does

A comprehensive batch image resizing solution to process multiple images simultaneously with professional-grade algorithms. Offers four distinct resizing modes, advanced quality control, and intelligent optimization for web, print, and more.

1. Four Intelligent Resizing Modes

1. 1) Max Dimension Mode

• Proportional scaling based on the largest dimension (width or height)
• Automatic aspect ratio preservation
• Perfect for web optimization with consistent maximum dimensions
• Range: 100–4000 px

> Ideal for creating consistent web galleries and responsive images.

1. 2) Fixed Dimensions Mode

• Exact width and height control with pixel precision
• Optional aspect ratio preservation with intelligent fitting
• Perfect for specific size requirements (thumbnails, avatars, banners)
• Smart cropping algorithm when aspect ratios don’t match

> Perfect for social media, e‑commerce, and template-based designs.

1. 3) Percentage Scaling

• Proportional scaling from 5% to 200% of original size
• Consistent scaling ratio across all images in a batch
• Predictable file size reduction for storage optimization
• Maintains original proportions

> Excellent for uniform scaling and storage space management.

1. 4) Target File Size Mode

• Automatic size optimization to achieve specific file sizes (50–5000 KB)
• Intelligent quality adjustment balancing size vs quality
• Great for email attachments and bandwidth constraints
• Progressive quality reduction until target size is reached

> Smart solution for file size constraints and bandwidth optimization.
