HEIC to PNG is the editing-pipeline version of the iPhone photo problem: a design tool, document system, or asset workflow that accepts only PNG, and a camera roll full of HEIC. The conversion decodes your photo and stores every pixel losslessly — nothing further is lost, ever, no matter how many times the PNG is reopened and saved.
Two honest expectations: the PNG will be noticeably larger than the HEIC (lossless storage always is — photos in PNG run big), and there is no transparency to gain, since photos are opaque. For sending photos to people rather than pipelines, HEIC to JPG is the smaller, friendlier choice; this page is for when the receiving software makes the rules.

Frequently asked questions
When should I pick PNG over JPG for a HEIC photo?
Pick PNG when software demands it or when the image will be edited repeatedly — PNG survives unlimited open-edit-save cycles with zero quality loss. For sharing, uploading, and everyday use, JPG is smaller and universally accepted.
Why is the PNG so much bigger than my HEIC?
HEIC is a modern, highly compressed format; PNG stores pixels losslessly with only modest compression. A 2 MB HEIC photo can become a 15-25 MB PNG — normal, and the price of the lossless guarantee.
Is the conversion itself lossless?
The decode preserves exactly the pixels your HEIC contains, rotation applied, and PNG stores them without any further loss. What was lossy happened once, at capture time on your phone.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
