Apple iPhones and iPads capture photos in High Efficiency Image Container (.HEIC) format by default to save storage space. However, HEIC images often fail to open on Windows PCs, web browsers, or older graphic software. Our free HEIC to JPG Converter solves this incompatibility by decoding HEIC/HEIF files locally inside your browser memory using client-side WebAssembly technology. Convert your photos to standard JPG or PNG files without uploading them to external servers.
Drag and drop your .heic or .heif photos into the upload box or click to select files from your iPhone, Mac, or PC.
Choose your target format (JPG or PNG) and adjust the compression quality slider to balance file size and visual fidelity.
Click Convert HEIC Photos to run WebAssembly decompression and download converted JPG files instantly to your device.
Utilizes compiled C/C++ libheif WebAssembly binary modules to decode Apple HEVC image bitstreams inside browser RAM at native processing speeds.
Process multiple iPhone camera photos at once with automated queue handling and one-click batch download capabilities.
Decodes and encodes photos 100% inside your browser sandbox. Your personal photos are never uploaded or stored on any remote cloud server.
High Efficiency Image Container (HEIC) is Apple's implementation of the HEIF (High Efficiency Image Format) standard based on HEVC (High Efficiency Video Coding / H.265) compression. HEIC reduces image file sizes by roughly 50% compared to JPEG while preserving equivalent or superior visual quality and supporting 16-bit color depth, alpha transparency channels, and burst image sequences. However, because HEVC requires specialized decoder hardware or software licensing, standard web browsers (such as Chrome or Firefox on desktop) cannot render HEIC images natively inside standard HTML <img> tags.
To overcome browser decoding limitations without sending sensitive photos across the network to cloud servers, our converter integrates libheif-js — a WebAssembly port of the C++ libheif library. When you upload a HEIC photo, WebAssembly parses the container metadata, extracts the HEVC keyframes, and decompresses raw YCbCr pixel arrays into an HTML5 Canvas ImageData object directly inside browser memory.
Once decoded onto the Canvas context, JavaScript uses native browser encoding APIs (canvas.toBlob()) to re-encode the image as a standard JPEG or PNG file. Users can tune the JPEG lossy compression quality target (from 10% to 100%) to optimize the output file size for web publishing or storage archiving. Because all decoding, rasterization, and encoding take place in RAM, your photos remain 100% private and protected from third-party data collection.
libheif-js) that runs directly inside your web browser. It decodes the HEVC compressed bitstream of your HEIC image into raw pixel data, which is then drawn onto an HTML5 Canvas and saved as a standard JPG or PNG file.
