Why Batch Processing Matters

Whether you're a photographer processing a shoot, a designer preparing web assets, or an e-commerce seller optimizing product photos, manual compression doesn't scale.

Pro Tips for Batch Compression

  • Organize before compressing — Group similar images together so you can use the same quality settings
  • Keep originals — Always save a backup of uncompressed images before batch processing
  • Test first — Compress a few sample images to verify quality before processing the full batch
  • Resize first if needed — Resizing before compression gives better results than just compressing
