Batch PNG Compression Guide

Compress multiple PNG files quickly and consistently for production workflows.

Why Batch Compression?

Teams ship dozens of assets per release—icons, screenshots, UI sprites. Batch compression ensures consistent quality, smaller downloads, and faster pages without manual effort.

Recommended Workflow

  1. Export design assets at exact display sizes (avoid oversized images).
  2. Group PNGs by type (logos, screenshots, UI) to apply consistent rules.
  3. Upload up to 5 PNGs at once with our tool, review results, and iterate.
  4. Download all compressed files as a single ZIP for handoff or deployment.

Quality Checks

  • Use side-by-side comparisons to verify crisp edges and text readability.
  • Confirm transparency renders correctly on light and dark backgrounds.
  • Spot-check final pages on real devices for visual artifacts.

Automating at Scale

For larger pipelines, integrate a compression step in CI or pre-commit hooks. Keep source assets in version control and generate optimized artifacts during build. This prevents regressions and keeps diffs small.

Troubleshooting

  • Large files: Reduce dimensions or color count where appropriate.
  • Blurry edges: Ensure assets are exported at 1x or whole-number scales.
  • Color shifts: Remove unnecessary color profiles; stick to sRGB for web.
