Compress ICO to 50KB

For 50 KB we keep just the essential favicon resolutions — typically 16, 32, and 48 px — and remove larger layers. This is the right target for lean favicons that load instantly and look sharp in browser tabs and taskbars. Pixel art and simple logo favicons compress well at these sizes. The ICO stays universally compatible while shedding the bulk that large embedded resolutions add. Ideal when you want the smallest valid favicon set. 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.
