Convert HEIC files instantly.

HEIC stands for High Efficiency Image Container. Apple adopted it as the default camera format starting with iOS 11 because it stores photos at roughly half the file size of JPEG without losing visible quality. This means your iPhone can hold twice as many photos in the same storage space. HEIC also supports features like Live Photos, depth maps, and HDR — things JPEG simply cannot do.

HEIC uses the H.265 video codec for compression, which is covered by patents. Microsoft doesn't include the decoder by default due to licensing costs. You can install a codec extension from the Microsoft Store, but the simplest solution is to convert HEIC files to JPG or PNG using HEIConverter — it works in any browser, takes seconds, and requires no software installation.

Every conversion runs entirely inside your browser using JavaScript and WebAssembly. Your files are never sent to any server — they never leave your device, period. There are no accounts, no tracking of file content, and no third-party processing involved. You can even verify this by disconnecting from the internet after the page loads and converting files offline.

Drop your HEIC file onto the converter (or tap Browse Files on mobile), select the JPG tab, adjust quality if needed, and click Convert. Your JPG downloads instantly. For multiple files, drop them all at once — HEIConverter processes them in parallel and lets you download everything as a ZIP.

Yes. HEIConverter supports up to 200 files per batch. You can drop an entire folder of HEIC photos and they'll all be converted in parallel. Each file shows individual progress, and when done you get a single ZIP download with all converted files named to match the originals.

JPG is best for sharing photos online or via email — it's universally compatible and produces small files. PNG is lossless and ideal for graphics, screenshots, or when you need transparency. WebP gives you the best compression for web use (smaller than JPG at the same quality) and works in all modern browsers. PDF is perfect when you need to combine multiple photos into a single document for printing, email attachments, or official submissions.

Yes. HEIConverter is fully responsive and works on iPhone, iPad, and Android devices. On iPhone, you can convert your own HEIC photos directly in Safari without installing any app.

HEIConverter uses libheif — the same open-source library that powers desktop HEIC viewers — compiled to WebAssembly for browser execution. The decode quality is identical to native software. For output encoding, it uses your browser's built-in Canvas API which produces industry-standard JPG, PNG, and WebP files.

Yes. HEIConverter automatically strips EXIF metadata (camera model, GPS coordinates, date) from all converted files. This is a privacy safeguard — when you share photos online, your location and device info won't be embedded in the file.

Yes. After your first visit, the conversion engine is cached locally in your browser. You can convert HEIC files without any internet connection — useful when traveling, on flights, or in areas with poor connectivity.
