How this works in your browser
Browsers outside Safari cannot decode HEIC natively, so this tool loads a WebAssembly HEIC decoder into the page to read the image data directly in your browser. Once decoded, the pixels are drawn onto an HTML5 canvas and exported as a JPEG through the browser’s own encoder. Both halves of that pipeline run locally, which is why the tool works identically on Windows and Android despite HEIC being an Apple-default format, and why your photos never need to be uploaded to a server to be converted.

| Watermark on output | Never | Common on free plans |
| Usage limits | None - free, unlimited use | Often capped per day or file size |
| Works offline once loaded | Yes, for most tools | No - requires a live connection |

Frequently asked questions
Why do my iPhone photos open as HEIC?
iOS has used HEIC as the default camera format since iOS 11 because it produces roughly half the file size of JPEG at similar quality. You can switch the camera back to JPEG under Settings, Camera, Formats, Most Compatible if you would rather avoid converting later.
Does this reduce photo quality?
There is a small amount of additional compression from the JPG re-encode, but it is not visible at normal viewing sizes.
Do I need an iPhone or Mac to use this?
No. Since the conversion runs in your browser, it works the same on Windows, Mac, Android, and iPhone.
Can I convert several HEIC photos at once?
Yes, drop multiple files and download them individually or as a ZIP.
Will the JPG be larger than the HEIC?
Usually yes. HEIC compresses more efficiently than JPEG, so the same photo typically takes noticeably more space as a JPG. That is the trade you make for universal compatibility.
What happens to Live Photos?
Only the still image is converted. The short motion clip attached to a Live Photo is not part of the JPG output.
Is EXIF data such as location kept?
Camera metadata may not carry across the re-encode. If you specifically want to strip location data before sharing a photo publicly, use the EXIF Viewer/Remover tool to check and remove it.
Are my photos uploaded to a server?
No. The HEIC file is decoded entirely inside your browser tab, so the photo never leaves your device.
