Batch Processing Features
- Drop up to 50 images at once (JPEG, PNG, WebP, AVIF, GIF)
- Smart quality: each image individually optimized for best compression ratio
- Download all results as a single ZIP file
- Mix formats in one batch — each file processed independently
Performance
Processing happens in a Web Worker off the main thread, so your browser stays responsive during compression. Typical batch of 20 photos (5MB each) completes in 10-15 seconds on modern devices. All processing is local — nothing leaves your device.
