How High-Fidelity Compression Works

Images are re-encoded with carefully tuned quality settings. If compression would increase file size, the original file is kept unchanged.

  1. Add one or more images by clicking Add Files or drag and drop.
  2. Set quality (default 85 for high fidelity), output format, and optional max edge length.
  3. Click Compress to process all files and see before/after sizes.
  4. Download individual files or all results as a ZIP archive.
All processing happens locally in your browser — your images are never uploaded to any server.
