Important Notes
  • PNG keeps transparency; JPEG does not. Use PNG/WEBP/AVIF when alpha transparency is required.
  • Lower quality values can introduce blur or blockiness; test outputs at real display size before publishing.
  • AVIF can deliver the smallest files, but WEBP may offer broader compatibility on legacy environments.
  • For professional pipelines, keep one untouched high-quality source and export multiple delivery variants.
Quick Checklist
  • 1Choose format by purpose (PNG fidelity, JPEG compatibility, WEBP/AVIF performance).
  • 2Enable resize if your target platform needs strict dimensions.
  • 3Set quality, convert, then verify size, transparency, and visible detail.
  • 4Download and use the exported version in your app/site/campaign.
