Question 1

What is a HEIC file?

Accepted Answer

HEIC (High Efficiency Image Container) is the default photo format on iPhones and iPads since iOS 11. It offers better compression than JPEG while maintaining quality, but is not supported by all applications and older operating systems.

Question 2

Is the conversion done in my browser?

Accepted Answer

Yes. The tool uses the heic2any library which decodes HEIC files using a WebAssembly port of the libheif decoder. Your photos never leave your device, which is important for privacy.

Question 3

Can I convert multiple files at once?

Accepted Answer

Yes. Select or drop multiple .heic or .heif files at once and all will be converted in sequence. Use Download All to get a ZIP archive with all converted JPGs.

Question 4

What quality setting should I use?

Accepted Answer

The default quality of 90% offers an excellent balance of file size and visual quality. For archiving use 95-100%. For web use where file size matters, 80-85% is usually sufficient.

Question 5

Why does my browser show a loading message the first time?

Accepted Answer

The first conversion requires loading the heic2any WebAssembly module (~1MB). This is cached after the first load so subsequent conversions start instantly.
