Compressing HEIC to Under 50 KB
For 50 KB the HEIC is converted to WebP around Q72 and resized to about 1280 px. This fits mobile thumbnails, social cards, and previews derived from iPhone photos. Because the source is already compressed, pushing to 50 KB compounds quality loss — acceptable at small display sizes. Use it for gallery tiles and list images rather than full-size views. Format conversion also ensures the result plays in every browser. 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.
Made for Users in Australia
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.

Frequently Asked Questions
Why do HEIC thumbnails look softer at 50 KB?
HEIC is already lossy; recompressing to 50 KB adds a second compression pass. At thumbnail sizes the softening is usually acceptable.
Can I keep HEIC output to save size?
You can, but browser support is limited. For web use, WebP output at 50 KB is more compatible and similarly efficient.
Can I compress files for myGov and state government portals?
Yes. myGov and state services often limit document sizes. Our tools help you get scans and forms under those limits before you upload them.
Will this work on slow regional or satellite NBN?
Yes. Because files are processed locally and never uploaded, the tool works well even on fixed-wireless and satellite connections where upload speeds are limited.
Does it respect my data cap?
Absolutely. Since nothing is uploaded, you only use data for the final, smaller download — ideal for Australians on metered mobile and NBN plans.
What file formats are supported?
We support PNG, JPG, WebP, AVIF, GIF, BMP, PDF, and many more. Check each tool page for its specific format support.
