How it works
ConvertCabin does this on a canvas inside your browser tab — your image is processed on your device and never uploaded. There's no queue, no daily cap and no account.
Because the work happens locally it stays free, unlimited and private, and keeps working offline once the page has loaded.
About HEIC and PNG
HEIC is the efficient format modern iPhones use; PNG is lossless and supported everywhere. Converting to PNG is handy when you need maximum quality or a format any app will open.
Frequently asked questions
How do I convert HEIC to PNG?
Drop your HEIC photos and download the PNGs. It runs in your browser — nothing to install.
Is it lossless?
Yes, PNG is a lossless format, so no extra compression is applied to the decoded image.
Is my photo uploaded?
No. It is decoded on your device and never sent anywhere.
What is a HEIC file?
HEIC (High Efficiency Image Container) is the format iPhones and iPads have used to save photos since iOS 11. It stores the same quality as JPG in roughly half the space, but many Windows apps and websites can't open it natively, which is why it's often converted.
What is a PNG file?
PNG is a lossless image format that supports transparency. It preserves every pixel exactly — great for logos, screenshots, and graphics with sharp edges — at the cost of larger files than JPG for photographs.
