HEIC (High Efficiency Image Container) is the default image format used by Apple iOS devices since iOS 11. It provides half the file size of JPEG at comparable quality, but lacks native support in many Windows applications.

Why is client-side HEIC conversion safer than online converters?

Most free online converters upload your personal camera roll to their servers to run ImageMagick or libheif. Doczing executes the decoder directly inside your browser sandbox, keeping your private pictures strictly confidential.

Does this converter compress or downscale my photos?

No. Doczing reads the full native resolution of your HEIC container and renders it 1:1 into a lossless PNG.

Can I convert multiple HEIC files at once?

Yes. You can select multiple HEIC images. Each image is processed sequentially to optimize device memory.
