How it works

  1. 1Choose multiple PNG images.
  2. 2Pick output format, quality and optional width limit.
  3. 3Process the queue and download results.

Privacy and limits

  • PNG quality behavior depends on the browser encoder.
  • WebP or JPG output often reduces size more than PNG output.
  • Transparent areas become white when exporting to JPG.

Batch PNG compression behavior

PNG files may not shrink much unless dimensions change or the output format changes to WebP or JPG.

The batch list makes it easy to see which files benefit from the selected output settings.

Common use cases

  • Optimizing documentation screenshots
  • Reducing transparent web graphics
  • Preparing multiple UI captures

Format notes

  • Use WebP for smaller transparent web assets when supported.
  • Use JPG only when a white background is acceptable.
  • Keep PNG when exact edges or transparency matter most.

Original test sample

  • Convert several screenshots to WebP and compare text edges before publishing.
  • For logos, check transparency before downloading the full ZIP.
