Frequently Asked Questions
1. Why choose HEIC to PNG instead of HEIC to JPG?
PNG is a lossless format, meaning it does not introduce compression artifacts when saving decoded iPhone photos—ideal for editing and print.
2. Are my HEIC files uploaded to a server?
No. All decoding and PNG encoding happen locally inside your web browser.
3. How do I convert HEIC to JPG for free on Windows or Mac?
Drop your .heic files into the converter above, leave the output on JPG, and click Download Result (or Download ZIP for a batch). It is 100% free with no watermark.
4. Are my personal iPhone photos uploaded to a server?
No. Decoding and JPG/PNG encoding happen locally inside your browser memory, so your photos never leave your device.
5. Will I lose image quality when converting HEIC to JPG?
JPG is a lossy format, but at the default quality of 92% the visual difference is virtually indistinguishable. Choose PNG if you need a 100% lossless copy.
6. Why does my iPhone take photos in HEIC instead of JPG?
Apple uses HEIC (High Efficiency Image Container, ISO/IEC 23008-12) to store photos at roughly half the file size of JPEG. However, many Windows programs and web portals still require JPG or PNG.
7. Can I batch convert dozens of HEIC files at once into a ZIP?
Yes! Add up to 100 HEIC photos at once and click "Download ZIP" to save all converted JPEGs in a single ZIP archive.
8. Does the converter fix sideways portrait iPhone photos?
Yes. Our decoder automatically applies the EXIF orientation tag so portrait iPhone photos always export right-side up.
9. Does converting HEIC to JPG strip hidden GPS location metadata?
Yes. Re-encoding through the browser canvas omits original EXIF GPS coordinates and camera serial numbers, protecting your location privacy when sharing online.
