Compress PNG

PNG (Portable Network Graphics) is a lossless image format widely used for web graphics, logos, and images requiring transparency. However, PNG files can be quite large. Our PNG compression tool uses advanced optimization algorithms to reduce file size significantly while maintaining visual quality. Unlike other compression tools that require uploading your files to a server, our tool performs all compression directly in your browser using modern web technologies. This means your images are completely private and never transmitted over the internet. Whether you are optimizing for the NBN, preparing myGov submissions, or sharing files across Australia's vast distances, this tool keeps your files light and quick to transfer — even on regional, fixed-wireless, and satellite connections, with no upload required.

Australian internet ranges from fast NBN fibre in the capitals to satellite and fixed-wireless in regional and remote areas. Keeping files small is essential for reliable sharing across the NBN, for uploads to myGov and state services, and for delivering content to audiences on Telstra, Optus, and Vodafone mobile networks across vast distances.

• myGov and state government portals enforce upload limits — compress scanned IDs and documents before lodging them.
• For regional users on fixed-wireless or satellite NBN, smaller files mean fewer timeouts on slower, higher-latency links.
• Australian mobile plans often include data caps; pre-compressed media saves data for end users on the go.
• When sharing with New Zealand and Southeast Asia, smaller attachments transfer more reliably across trans-Tasman links.
