Process hundreds of images in seconds. Resize, compress, convert, and watermark - all from the command line.
💡 E-commerce? Photography? Web dev? Stop processing images one by one. Batch everything.
The Problem: Image processing is tedious
- Resize 500 product photos one by one? Hours wasted.
- Need to convert HEIC to JPG? Manual hell.
- Remove GPS data before posting? Security risk.
- Compress for web? Which tool? Which settings?
The Solution: Batch process everything
- 🚀 Handle thousands of images at once
- ⚡ One command, done in seconds
- 💾 Save 70%+ file size while maintaining quality
- 🔒 Privacy-friendly (strip GPS/EXIF data)
- 💰 Free and open source
