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
