Convert HEIC to PNG
To convert HEIC to PNG, add your .heic file below and press the button: it's processed on your own device and you download the result, with nothing uploaded. It's free, needs no account, and works with files up to 500MB.
Tip: add several files at once to convert them in one go and download them as a ZIP.
About converting HEIC to PNG
HEIC (.heic) files can be converted to PNG entirely in your browser — no software to install, no file upload, and no account required. The conversion runs on libheif (the reference HEIC decoder) compiled to WebAssembly, plus the browser's Canvas API directly on your device.
Technical comparison
| HEIC | PNG | |
|---|---|---|
| Category | image | image |
| Compression type | Lossy (HEVC intra-frame) | Lossless (DEFLATE) |
| Typical file size | Small — roughly 40–50% smaller than an equivalent JPEG | Moderate — larger than JPEG for photos, smaller for flat-color graphics |
| Transparency support | Yes | Yes (full 8-bit alpha channel) |
How to convert HEIC to PNG privately
Every step below runs on libheif (the reference HEIC decoder) compiled to WebAssembly, plus the browser's Canvas API inside this browser tab. Your .heic file is never uploaded to a server — there's no network request carrying it anywhere.
Add your HEIC file
Drag and drop, or click to select, a file (.heic). It's read straight from disk into browser memory — no upload step exists.
Convert locally
FreePrivateConvert converts it to PNG using libheif (the reference HEIC decoder) compiled to WebAssembly, plus the browser's Canvas API, entirely within this browser tab.
Download the result
Save your converted .png file. It only ever existed in this tab's memory — closing the tab without downloading discards it completely.
Convert HEIC to PNG with ffmpeg (command line)
Prefer the terminal? This page uses libheif, the reference HEIC decoder, running in your browser; the equivalent ffmpeg command is:
ffmpeg -i input.heic output.png- -i input.heic
- Your HEIC file.
- output.png
- The PNG file to create. ffmpeg picks the container from this extension.
Desktop ffmpeg only reads HEIC in recent releases (7.1 and newer), and iPhone photos can still fail on some builds.
Don't have ffmpeg installed? You don't need it: use the converter at the top of this page. It runs this conversion on your own device, and your file is never uploaded.
FAQ
- Is my file uploaded anywhere?
- No. Your file is read and processed inside this browser tab and never leaves your device. You can confirm it in your browser's developer tools: the Network tab shows no upload.
- Does converting HEIC to PNG reduce quality?
- No further loss: PNG is lossless, so the result looks exactly like the decoded HEIC, though the file is usually larger and any compression artifacts already in the source stay.
- Is there a file size limit?
- Yes: 500MB per file. There's no account and no limit on how many files you convert.
- What's the difference between HEIC and PNG?
- HEIC (High Efficiency Image Format) and PNG (Portable Network Graphics) store data differently. HEIC: lossy (HEVC intra-frame). PNG: lossless (DEFLATE). PNG is a lossless, compressed image format with full alpha transparency — the standard choice for graphics, screenshots, and anything with sharp edges or text.
- Why convert HEIC to PNG?
- Common uses for PNG: Screenshots; Logos and icons; UI/design assets requiring transparency. Lossless DEFLATE compression means no artifacts around text, logos, or hard edges, unlike JPEG.
- What MIME type does a .png file use?
- image/png, the standard type for Portable Network Graphics.
- What is the ffmpeg command to convert HEIC to PNG?
- Run: ffmpeg -i input.heic output.png. This page does the same conversion with libheif, the reference HEIC decoder, running in your browser, so you don't need to install ffmpeg. Desktop ffmpeg only reads HEIC in recent releases (7.1 and newer), and iPhone photos can still fail on some builds.
