In-Browser HEIC/HEIF via libde265 WASM

Apple High Efficiency Image Containers (HEIC) are traditionally unreadable by standard web engines. ToolAcre compiles a sandboxed C++ implementation of libde265 straight to WebAssembly, parsing raw H.265 I-frames in user memory at native multi-threaded speeds.

Alpha Channel Preservation & RGBA

Converting transparent assets between modern codecs requires exacting control over 32-bit pixel buffers. Our Canvas 2D image matrix extracts discrete RGBA clamping maps, preventing fringing, premultiplied halo artifacts, and color fringing when shifting transparent PNGs to AVIF or WebP.

Confidential Zero-Egress Sandbox

Enterprise media, internal design mockups, and medical captures frequently violate security compliance when sent to cloud transcoding APIs. Because ToolAcre executes 100% on your device's CPU/GPU, your files never touch an external socket or trigger an egress packet.
