Batch Image Resizing — Multiple Image Resizer
Set custom Width & Height (up to 8000px). Choose Fit, Fill, or Stretch mode. Resize hundreds of images at once — works as a group image resizer across nested sub-folders too. Available as a multiple image resizer download for Windows.
Automatic Nested Sub-Folder Conversion
Activate Sub-Folder Mode to recursively process all nested folders. No manual selection needed — scans entire directory trees automatically.
Safe Delete Original Files
Files are moved to the Recycle Bin — not permanently deleted. Clean up originals after conversion safely. Perfect for PNG→WebP replacement workflows.
Parallel Workers (Multi-Core)
Scale up to 32 parallel workers. Utilizes all CPU cores efficiently. Auto-scale assigns optimal thread count. Dramatically reduces large-batch processing time.
High-Speed Batch Processing Engine
Multi-threaded engine handles 1,000 to 100,000+ files with consistent speed and stability. Auto-Scale Workers dynamically optimizes CPU usage.
Real-Time Conversion Dashboard
Live display of processed files, success/failed counts, real-time speed (files/sec), ETA remaining, and current status.
Drag & Drop Input / Output
Drop folders directly into the app window or browse manually. Automatic scanning of all supported image formats in the selected folder.
