HEIC to JPG — Free Online Tool

Why convert HEIC to JPG

Since 2017 Apple devices have saved photos in HEIC, a format that stores high quality in a small file but is not opened by many Windows programs, older photo editors, web forms, and messaging tools. Converting to JPG produces a file that opens everywhere, from email and document software to almost every website upload field. HEIC to JPG decodes the original with the actively maintained heic-to engine and re-encodes it as a JPG, so you can share or upload the photo without compatibility errors.

How the conversion works

The tool reads your HEIC file and decodes it using WebAssembly that runs inside the browser. The decoded picture is drawn to a canvas and exported as a JPG at the quality you select between 60 and 100 percent. Because the decoder is a modern WebAssembly build rather than older code that relied on string evaluation, it runs under a strict Content Security Policy without weakening site security. Each photo is processed in memory and offered straight back to you as a download.

Quality and file size

JPG is a lossy format, so the quality slider controls the balance between sharpness and file size. A setting around 90 percent keeps the photo visually identical to the HEIC original while producing a manageable file, and lowering it toward 60 percent makes the file noticeably smaller for email or web use. HEIC files are often half the size of the JPG they produce, because HEIC compresses more efficiently, so expect the converted JPG to be somewhat larger than the source.

Privacy and safety

Your photos never leave your device. The HEIC file is decoded and re-encoded locally in the browser, with nothing uploaded, stored, or shared. This local-only approach is important for personal photos, since you can convert family pictures, screenshots, or private images without handing them to a third-party server. When you close the page the files are cleared from memory automatically.

Browser and device support

HEIC to JPG runs in current versions of Chrome, Firefox, Safari, and Edge on Windows, macOS, Linux, Android, and iOS. No app or extension is needed. You can convert several photos in one go, and the responsive layout keeps the quality slider and download button reachable on a 375 pixel screen. Converting a single 12 megapixel iPhone photo typically completes in a couple of seconds.

About the HEIC format

HEIC, short for High Efficiency Image Container, is the still-image form of the HEIF standard and has been the default on iPhones and iPads since iOS 11 arrived in 2017. It uses the same efficient compression family as modern video, which lets it store a photo at high quality in about half the space of a comparable JPG, and it can also hold extras like depth maps and bursts. The drawback is reach: Windows needs an add-on to view HEIC, and many websites, editors, and chat apps simply reject it. Converting to JPG removes that friction while keeping the picture that matters.

Tips for sharing converted photos

Keep the quality slider near 90 percent when the photo will be printed or viewed closely, and lower it toward 70 percent when you only need a small file for a quick share or a web form. Convert in batches when you have a whole album, since the tool processes each file in turn and downloads them as standard JPGs. Remember that converting strips the HEIC-specific extras such as depth data, leaving a flat photo, which is exactly what most websites and recipients expect. Keep your HEIC originals on your device if you want to preserve the smaller files and any Apple-only features.
