HEIC to JPG
Turn iPhone HEIC photos into JPG, PNG or WebP pictures that open everywhere, without uploading them.

Since iOS 11, iPhones and iPads save photos as HEIC by default. The format stores pictures with the HEVC (H.265) video codec inside a HEIF container, which keeps roughly the same visual quality as JPEG in about half the space. The catch is compatibility: Chrome, Firefox and Edge cannot display HEIC, many websites, print shops and online forms refuse it, and Windows needs extra codecs from the Microsoft Store before it can even show a thumbnail. This converter turns HEIC and HEIF files into JPG, PNG or WebP so they open on any device and upload anywhere. Drop one photo or a whole folder's worth, pick the output format, and download each file on its own or everything together as a ZIP.

About HEIC to JPG
The conversion runs entirely in your browser. The first time you use it, the page loads a WebAssembly build of libheif (about 3 MB, cached afterwards), and from then on every file is decoded and re-encoded on your own computer or phone. Nothing is uploaded, so private photos, documents you photographed and pictures of your children never leave your device. Each output keeps the original file name with the new extension (IMG_1234.HEIC becomes IMG_1234.jpg), the rotation stored in the HEIC is applied so portrait shots come out the right way up, and camera metadata such as GPS location is not copied, which is a useful side effect if you are about to share the pictures publicly.
Which format should you choose? JPG is the safe default: every app, website and printer accepts it, and at 90% quality the result is visually indistinguishable from the original, although the file will usually be 1.5 to 2 times larger than the HEIC because JPEG compresses less efficiently. PNG is lossless and much larger, worth it only when you plan to edit the image further. WebP gives smaller files than JPG at the same quality and works in all modern browsers, which makes it a good choice for websites. If you would rather not convert at all in future, you can set your iPhone to shoot JPEG under Settings, Camera, Formats, Most Compatible, or keep HEIC and let iOS convert automatically when you copy photos to a computer (Settings, Photos, Transfer to Mac or PC, Automatic).
An iPhone photo is really a mosaic of tiny pictures
When you open a 12 megapixel iPhone HEIC in a hex editor, you will not find one big image. You will find a grid of 48 separate HEVC images, each 512 by 512 pixels, plus a small instruction item called a grid that says how to lay them out in eight columns and six rows. The decoder decodes every tile and stitches them together, trimming the edges to the real photo size.
Apple does this because HEVC was designed for video and hardware decoders are tuned for frame sizes like HD or 4K. Small tiles let the phone encode and decode them in parallel, show a region of the photo without decoding the rest, and stay within limits that every HEVC chip supports.
The same file often carries more: a tiny thumbnail, a depth map for Portrait mode, a gain map that tells HDR screens how much brighter each area should be, and the EXIF block. HEIF was designed from the start as a container for collections of images and their relationships, which is why one file can hold a whole burst or an image sequence.
