About this tool

Compress PNG images in batches while keeping PNG output, with private browser-local processing and no file upload or account. Start immediately without creating an account or sending the source file to NexaForge.

Reduce PNG files locally

The tool re-encodes selected PNG images and shows before-and-after file sizes with batch download. Transparency remains available, while savings depend on image content.

Choosing PNG compression or another format

Icons, screenshots, and transparent assets often need to remain PNG. When web transfer size matters more, compare a PNG-to-WebP result before choosing the final format.

How to use this tool

  1. Choose one or more PNG images.
  2. Keep PNG output selected and process them.
  3. Inspect transparency and size, then download.

Private, local processing

Your input is processed locally by the browser on this device. NexaForge does not upload the file or text to its server, which keeps private work under your control.

Frequently asked questions

Will NexaForge upload or store my input?

No. Processing happens locally in your browser, and NexaForge does not receive or store the source file or text.

Will the compressed PNG keep transparency?

PNG output supports transparency. Inspect the preview before download to confirm it suits your asset.
