JPG to WebP output checks

  • Check the output KB or MB against the upload limit.
  • Verify pixel dimensions and whether transparency is preserved.
  • Open at 100% size to check text and edge sharpness.
Processing method

The browser decodes the source pixels and encodes them in the selected format. Lossy output changes with quality, and JPG cannot preserve transparency.
