How PNG to HEIC conversion works
Need to convert PNG files to HEIC? PixelKit does it in one click, right in your browser. The converter reads your PNG file locally, renders it to a canvas, and re-encodes it as HEIC using the browser's own image pipeline. Because nothing is sent to a server, there is no upload wait, no file-size limit from a backend, and no privacy risk. Your photos, ID scans and documents stay on your device the entire time.
The tool works offline after the first page load, on mobile and desktop, and produces standard HEIC files accepted by portals, email clients and design apps. Drag a PNG file, pick HEIC as the output, and download the result. Multiple files can be converted in one batch, and results appear side by side for easy comparison.
No account, no watermark, no email gate. Just the file you need, at the size you need it.
