Why cannot Windows or web forms open HEIC files by default?

HEIC uses the HEVC (H.265) video codec inside an ISOBMFF container. Many web applications and operating systems omit HEVC playback support due to licensing fees and legacy software constraints.

Does converting HEIC to JPG reduce photo quality?

HEIC to JPEG conversion re-encodes pixel data, but at high quality parameters (e.g., 85–90%), the visual difference is imperceptible to the human eye while restoring broad platform compatibility.

Is there a file count limit when converting iPhone photos?

No. Because processing uses your own device RAM and CPU rather than server quotas, you can convert as many photos as your browser memory permits.

WASM iPhone Local Decoder

Resolving the iOS format wall on non-Apple platforms

iPhones capture photos in High Efficiency Image Container (HEIC) format by default to conserve internal flash storage. While HEIC offers superior compression efficiency, Windows PCs, legacy CMS tools, and web submission forms often refuse to read or decode `.heic` files. Zapixal embeds a WASM-compiled libheif decoder directly inside your browser. When you drop an iPhone photo into the app, your device decodes the underlying HEVC bitstream locally and rasterizes it to a clean, universally compatible JPEG array.
