HEIC to JPG Converter

A HEIC to JPG converter turns the photos an iPhone saves as .heic into ordinary .jpg files that open everywhere. HEIC is what the camera writes when its format is set to High Efficiency, the default on iPhones since iOS 11 in 2017. It stores a photo in noticeably less space than JPEG, but the file stops being welcome once it leaves Apple devices: Windows sends you to the Microsoft Store for an extension, upload forms reject the name, and plenty of editors and print services will not open it at all.

HEIF and HEIC are two names for nearly the same thing. HEIF, the High Efficiency Image File Format, is the container, standardized by MPEG as ISO/IEC 23008-12. HEIC is a HEIF file whose picture is compressed with HEVC, the H.265 codec. This page reads both, so a .heif photo from an Android phone converts exactly like a .heic from an iPhone, and a heif to jpeg job needs no separate tool.

Here is a typical run. You email yourself IMG_4127.HEIC, a 4032 x 3024 photo, and drop it here, and it starts converting at once. The first HEIC file added in a tab downloads the decoder, libheif compiled to WebAssembly and about 470 KB compressed, which runs in a background worker so the page stays responsive. The row then shows a thumbnail, the input size, an arrow, the JPG size and the change in file size, and clicking the thumbnail opens the 4032x3024 result with Before and After views. The JPG is usually the bigger file at the default quality of 90, because JPEG needs more bytes than HEVC to hold the same detail. Lower the Quality slider when the photo has to fit under an upload limit.

A few things do not make the trip. The photo is decoded to pixels and re-encoded through a canvas, so EXIF data, including the capture date, camera settings and GPS location, is not copied into the JPG, and neither is the embedded color profile. A HEIC file can hold more than one image; when it does, the primary image is converted and the note under its row says how many the file held. The short video of a Live Photo is stored in a separate file, so it is never part of the conversion.

Everything runs client-side, and the photos are never uploaded. Each file is identified by its first bytes rather than its name, so an iPhone photo renamed to .jpg is still recognized as HEIC, and a file in another format is turned away with a link to the converter that handles it. HEIC files over 100 MB and images over 100 megapixels are refused with a message instead of freezing the tab. The tool is free, no signup, with a daily conversion limit.

• Your photos are decoded and saved as JPG inside this browser tab. The HEIC file is never uploaded, and the only download is the decoder itself.
• The daily limit check sends the tool name and a device identifier, plus your account token if you are signed in. No photo data is part of it.
• After a batch, the page records how many photos converted, their combined size in bytes and the output format. File names and image contents are never sent.
• GPS coordinates, the capture date and other EXIF fields are not written into the JPG. If you need the location or date later, keep the original HEIC.
• Converted JPGs stay in the tab's memory until you remove them, press Clear All or close the page. No copy is kept on a server.
