Technical Architecture

Understanding HEIC to AVIF In-Memory Conversion

Converting High Efficiency Image Container (HEIC) to AV1 Image File Format (AVIF) involves a transformation between two specialized encoding specifications. HEIC leverages modern Discrete Cosine Transform (DCT) and intra-frame directional prediction from HEVC (H.265). It encapsulates high-depth color, transparency alpha masks, and auxiliary depth channels with half the storage footprint of JPEG.

AVIF packages AV1 intra-frames inside an ISOBMFF container, providing cutting-edge compression ratios and wide-color-gamut HDR color handling.

Unlike traditional file conversion utilities that transmit sensitive files across the public internet to third-party server farms, MixConvert processes your data locally inside your web browser sandbox using compiled WebAssembly workers. Decoded client-side in browser RAM using compiled libheif and libde265 WebAssembly workers, transforming directional prediction blocks directly into 32-bit linear RGBA canvas memory. Processed via in-browser libavif WebAssembly builds or native browser ImageDecoder APIs directly in local memory. Once you close the browser tab, all temporary memory buffers are completely garbage collected.
