Initializing High-Speed Workspace
Loading lossless client-side canvas engine with zero server telemetry.
Unlock your iPhone HEIC and HEIF photos with archival-grade precision. 100% private WebAssembly processing in your browser with zero server uploads and lightning-fast batch downloads.
Introduced by Apple in iOS 11 and macOS High Sierra, the HEIF (High Efficiency Image File Format) standard uses modern H.265/HEVC video intra-frame compression techniques to store visual assets. Compared to the 30-year-old JPEG standard (ISO/IEC 10918-1), HEIC delivers double the data compression efficiency while expanding color depth from 8 bits (16.7 million colors) to 10-bit and 12-bit wide-gamut HDR spaces.
A 12-megapixel iPhone photo captured in HEIC typically occupies 1.5MB to 2.2MB of storage, compared to 3.8MB to 5.0MB for an equivalent JPEG.
Older versions of Windows (Windows 7/8/10 without paid HEVC codec packs), Android TV systems, and standard government web forms reject HEIC uploads.
Our in-browser WebAssembly decoder parses the HEVC NAL units directly in client memory, producing standard sRGB JPEGs with zero network overhead.
| Technical Feature | Apple HEIC (.heic) | Standard JPEG (.jpg) | Lossless PNG (.png) |

| Native Color Bit Depth | Up to 16-bit (Display P3) | 8-bit per channel (sRGB) | Up to 16-bit per channel |
| Relative File Size | ~50% of JPEG | Baseline (100%) | 250% – 500% of JPEG |
| Global Platform Support | Apple Native, Limited PC | 100% Universal | 100% Universal |
| Alpha Channel Transparency | Yes (Auxiliary alpha layer) | No (Opaque only) | Yes (Full 8-bit alpha) |
iPhone photo rolls contain deeply personal data: family portraits, financial records, medical documents, and real-time GPS locations embedded within EXIF tags. Sending these files to unknown third-party conversion sites introduces severe privacy vulnerabilities.
By running our compiled libheif C++ decoder directly in your browser's WebAssembly virtual sandbox, Ubify Tools ensures that no byte of your images leaves your computer or smartphone. All computation happens locally in RAM, delivering unparalleled privacy and near-instant processing speeds.
HEIC (High Efficiency Image Container) is Apple’s default image format for iPhones and iPads using iOS 11 and later. Based on HEVC (H.265) compression, it stores photos at approximately half the file size of a standard JPEG while retaining superior 10-bit color. However, many Windows programs, Android devices, website uploaders, and legacy photo editors cannot natively open HEIC files, making conversion to JPG essential for universal compatibility.
Never. Unlike most online file conversion utilities that send personal photos across the web to be processed on remote cloud servers, Ubify Tools executes the complete HEIC decoding pipeline inside your browser using a local WebAssembly (Wasm) binary. Your photos never leave your device memory.
Our conversion engine uses high-precision color matrix transformation that preserves the dynamic range and clarity of Apple’s 10-bit camera sensors. By exporting at 92% to 95% JPEG quality, the resulting image is visually indistinguishable from the original HEIC while remaining universally viewable.
Yes. The converter utilizes multi-threaded browser Web Workers to process batch image queues in parallel, fully utilizing your computer’s multi-core CPU. You can download all converted files simultaneously as a structured ZIP archive.
Yes. Crucial photographic metadata—including capture date, camera model, shutter speed, aperture, and focal length—is transferred to the output JPG file, ensuring your photo libraries stay organized chronologically.
