How to compress png images online

Reduce PNG file size with a simple browser-based workflow. For photographs, converting to JPG may produce a much smaller file.

Why use File Chisel?

File Chisel is designed around the outcome you need rather than a long list of technical settings. Choose a supported image, set the requirement, process it, and download a separate finished copy.

Is my image uploaded?

For the image tool on this page, processing happens in your browser using browser image APIs. The source file is not sent to a File Chisel server by this application.

What happens to the original?

Your original stays on your device. File Chisel creates a separate output file for download.

Tips for a better result

  • Use JPG for photographs when transparency is not required.
  • Use the exact target size when a website or form provides a KB or MB limit.
  • For very large images, reducing dimensions can cut file size more than quality changes alone.

Frequently asked questions

Can PNG always reach a tiny target size?

Not always. PNG is lossless and can remain large for detailed images. For photographs, JPG or WebP may be more efficient.

Does File Chisel preserve transparency?

PNG-to-PNG workflows can preserve transparency, but converting to JPG cannot.
