How it works

Compress PNG re-checks the output before download. If the result is not smaller, the original bytes are kept.

  1. 01Add a supported PNG file. The real type is checked before Compress PNG runs, not only the extension.
  2. 02Use the controls that belong to this task: Quality, Width, Height. Files over the stated limits are rejected.
  3. 03Check size, format and page or pixel counts on the result before downloading. Compression tasks keep the original when they do not save space.
