What is HEIC, and why does my iPhone use it?
HEIC (High Efficiency Image Container) is the file format Apple has used by default for iPhone and iPad photos since iOS 11 (2017). It is Apple's implementation of the HEIF standard, and it stores images using HEVC (H.265) compression. The big advantage is size: a HEIC photo is roughly half the size of the same picture saved as JPG, while keeping equal or better visual quality. That is why your iPhone can hold thousands of high-resolution photos without filling up.
The problem is compatibility. HEIC is an Apple-first format. The moment you move a HEIC file off your iPhone — emailing it, uploading it to a website, sending it to a Windows PC or an Android phone, or attaching it to a job application — the receiving device often has no idea what to do with it. JPG, by contrast, has been the universal photo format for nearly 30 years and opens on literally everything. Converting HEIC to JPG is the simplest way to make your iPhone photos truly portable.
Why won't my HEIC photos open on Windows, Android, or the web?
Older versions of Windows 10 and 11 cannot open HEIC without installing Microsoft's paid HEVC codec from the Store. Many Android phones, especially before Android 10, have no native HEIC support at all. Web forms — think government portals, job sites, marketplaces like eBay or Etsy, and most “upload your photo” boxes — frequently reject HEIC outright and only accept JPG or PNG. Even when a site does accept it, the image may fail to display.
This is the single most common reason people search for a HEIC to JPG converter: they have a photo trapped in a format the other person's device refuses to open. Converting to JPG removes that wall instantly. Once it is a JPG, it opens on Windows, macOS, Android, Linux, every browser, every chat app, and every upload form — no codec, no plugin, no app.
Will I lose quality converting HEIC to JPG?
For everyday use — sharing, printing, uploading, posting — the answer is effectively no. We export JPG at 92% quality, which is visually indistinguishable from the original for normal viewing. You will not see a difference on a phone, a monitor, or a print.
The honest technical note: JPG uses lossy compression, so a converted JPG is mathematically not byte-for-byte identical to the HEIC source, and a JPG file is usually larger than the HEIC it came from (because JPG is a less efficient format). If you need a truly lossless copy for archiving or heavy editing, use our HEIC to PNG tool instead — PNG is lossless. For 99% of real-world needs, JPG is the right choice: small, universal, and high quality.
Is it private? Are my photos uploaded to a server?
Nothing is uploaded. This converter runs entirely inside your browser using WebAssembly. Your HEIC files are decoded and converted on your own device, and the image data never leaves your computer or phone. We have no server that receives your photos, which means we physically cannot see them, store them, or leak them.
That matters because photos are personal. Many free online converters upload your images to their servers, where they may be cached, logged, or scanned. With LivePhotoKit there is no upload step at all — which also means it works offline once the page has loaded, and there is no file-size limit imposed by an upload server. No sign-up, no email, no watermark stamped on your image.
How to convert HEIC to JPG in batch
If you have a whole camera roll to convert, you do not need to do it one by one. Tap “Choose Files” and select as many HEIC files as you like — dozens or hundreds. Each one is decoded and converted to JPG locally, and you can download them individually or grab the entire set as a single ZIP archive. This is the fastest way to prepare a batch of iPhone photos for a website, a print order, or a backup to a Windows PC.
Because everything runs on your device, batch speed depends on your own hardware rather than a server queue, so there is nothing to wait in line for. On a modern phone or laptop, a large batch finishes in seconds.
