📘 How PNG compression with guarantee works

  1. Only PNG images are accepted. Non-PNG files show an error.
  2. First, we apply your resize and metadata settings.
  3. If the result is not smaller than the original, we automatically reduce dimensions (step by step) until the PNG file size is below the original.
  4. Final output is always smaller – example: 500KB PNG → compressed PNG <500KB.
  5. 100% local, no upload, private.
