How do I open HEIC files on Windows?
Windows can’t open iPhone HEIC photos without extra codecs, and the Store’s HEVC extension costs money. The pragmatic fix: convert the HEIC files to JPG — drop them on the converter below and every photo comes back as a universally-open JPG, processed in your browser without uploading anything.
- Drop the HEIC files. Batch is fine — the whole camera-roll export at once. The decoder runs in your browser via WebAssembly.
- Download as JPG. Each photo returns as a JPG that opens in Photos, Paint, Office, ancient printers — everything. Batch results come as a ZIP.
- Optional: stop the problem at the source. On the iPhone: Settings → Camera → Formats → Most Compatible makes future photos JPG. (High Efficiency saves space but recreates this problem monthly.)
A hundred vacation photos convert in about a minute. EXIF rotation is honored, so nothing comes out sideways.
Why does Windows refuse HEIC in the first place?
HEIC uses HEVC compression, which carries patent licensing — so Microsoft ships the codec as a paid Store add-on rather than bundling it. Free codec packs from the internet are a classic malware vector. Converting the files needs no codec install at all, which is why it is the safer answer.
JPG or PNG for the conversion?
JPG for photos — small files, universal, visually identical at the quality this tool uses. PNG only if you need lossless pixels (screenshots, graphics); photo PNGs run 5–10× larger for no visible gain.

Frequently asked questions
Do I lose quality converting HEIC to JPG?
Not visibly. The converter decodes the full image and re-encodes at high JPG quality; the difference is imperceptible on any screen. Keep the HEIC originals if you want an archival copy.
Are my photos uploaded to convert them?
No — decoding happens in your browser. Personal photos stay on your machine, which is the whole point of QuietPix.
What about HEIC on older Macs or Android?
Same fix, same tool — the converted JPGs open everywhere. The converter runs in any modern browser on any OS.
