FAQ

Does this upload my photos?
No. Everything runs locally in your browser. Your files never leave your device.

Can I use it offline?
Yes. After the page loads, disconnect from the internet and convert as normal.

Why PNG instead of JPG?
PNG is lossless and can keep transparency. JPG is usually smaller for photos. If you want JPG, use HEIC to JPG.

Why is the PNG larger?
HEIC is heavily compressed. PNG keeps more raw data, so it is often larger.

Does this preserve Live Photo motion?
No. PNG is a still image. This converts the photo frame, not the motion.
