Is the HEIC to PNG converter free?

Yes. Transcodr is free with no accounts, watermarks, or hard limits beyond your device's available memory.

Are my files uploaded to a server?

No. The conversion runs locally via ffmpeg compiled to WebAssembly, so your HEIC file never leaves the browser tab.

Is transparency preserved?

Yes — PNG supports an alpha channel, so transparent areas in your HEIC stay transparent.

How do I convert HEIC to PNG?

Drop your HEIC file above (or click Browse) — the output is already preset to PNG — then click Convert and download the result.

01 / Engine

Real ffmpeg, compiled to WebAssembly.

Same library Netflix, YouTube, and basically every command-line video tool relies on, running in a Web Worker. Pipe a file in, run a command, pipe bytes back out.

02 / Privacy

Nothing leaves the tab.

No uploads, no accounts, no telemetry beyond an anonymous pageview. We couldn’t see your files if we wanted to — there’s no server in the loop.

03 / Limits

It is, after all, a tab.

Files up to a few hundred megabytes convert comfortably. Beyond that, your browser starts asking pointed questions. Use the desktop ffmpeg for 4K masters.
