How to use the HEIC to PNG converter
- Pick the .heic or .heif files.
- If the photos are bigger than your project needs, scale them down under More settings first.
- Convert to PNG and download them.
Big files, on purpose
A lossless copy of a 12-megapixel phone photo is heavy: a HEIC of roughly 2 MB can turn into a 15–25 MB PNG. That is fine for a master you will edit and then export once, but a poor choice for sending to someone.
If the photos are just being sent or posted, convert HEIC to JPG instead. PNG earns its weight only as an in-between copy that will not degrade.
Colour depth and Android HEIF
Newer iPhones record in the Display P3 colour space and sometimes with 10-bit data. The PNG is saved at 8 bits per channel without the P3 profile, so the most saturated reds and greens may look a touch less vivid than on the phone screen.
HEIF pictures from Samsung and other Android handsets share the container format, so they go through the same decoder. An alpha plane, if a file has one, is carried into the PNG.
Using the PNG in an edit
Composite work, such as placing a person cut from an iPhone photo onto a new background for a thumbnail, needs a source that holds up through several saves. Bring the PNG into your editor, finish the work there, and export the final image as JPG or WebP for the web.
Rotation recorded by the phone is applied before saving, so portrait shots open upright in every program, and camera metadata is left out of the PNG.
Questions
Why is the PNG so much bigger than the HEIC?
HEIC uses lossy video-style compression; PNG stores every decoded pixel exactly.
Can I drop a whole phone export folder?
Yes. HEIC and HEIF files in it are converted, other files are skipped, and the ZIP button collects the results.
