What is a HEIC file?
HEIC is the format iPhones and iPads have used for photos since iOS 11. Built on the HEVC video codec, it stores photos at roughly half the size of an equivalent JPG — but outside the Apple ecosystem support is patchy. Windows needs paid codecs, many websites reject HEIC uploads, and most printing services will not accept it.
In short, HEIC is Apple's iPhone photo format. It is best for staying on Apple devices — for everything else, convert it first. Its main limitations are poor support on Windows, Android, the web, and most upload forms; licensing restrictions keep adoption low.
Why convert HEIC to JPG?
JPEG has been the default format for photographs since 1992. It uses lossy compression tuned for natural images, which lets it shrink photos to a fraction of their raw size while keeping them visually convincing. Virtually every camera, phone, browser, and app on the planet can open a JPG.
Converting from HEIC to JPG makes sense when you need photographs, screenshots of photos, email attachments, and anywhere maximum compatibility matters more than perfect fidelity. JPG is opened by every browser, OS, and image application ever made.
Note that JPG does not support transparency: any transparent areas in your HEIC will be filled with a white background during conversion.
How to convert HEIC to JPG
Drag and drop one or more HEIC files into the box above (or click to browse). Adjust the quality slider if you want smaller files or higher fidelity, then press Convert. Each file is decoded and re-encoded as JPG on your own device in a second or two, and you can download results individually or grab everything as a ZIP.
Unlike most online converters, FileLark never uploads your files to a server. The conversion runs entirely inside your browser using modern web technology, which means it works offline once the page has loaded, there are no file size queues or daily upload limits, and your images can never be stored, scanned, or leaked — they simply never leave your device.
