What is HEIC and why convert it to JPG?
HEIC (HEIF) has been the default iPhone photo format since iOS 11. Thanks to HEVC compression it takes roughly half the space of a JPG of similar quality. But older Windows versions, many websites, job and visa application forms, online shop back-ends and some print services don’t accept HEIC. Converted to JPG, your photo opens on every device and uploads to any form.
Converted in your browser, never uploaded
Conversion runs in your browser with a WebAssembly build of the open-source libheif library, so your photos are never sent to a server. The decoder is downloaded once (about 650 KB) when you pick your first HEIC file; browsers that can open HEIC natively, such as Safari, don’t even need that. The photo’s rotation is applied automatically.
JPG or PNG, and which quality?
JPG is the right choice for photos: 85–90% quality gives small files with no visible loss. PNG is lossless but makes photos several times larger; pick it only if you will edit the image further. HEIC’s 10-bit colour and HDR information can’t be carried over to 8-bit JPG/PNG, and for Live Photos or bursts only the main still image is converted.
EXIF and location data
By default the output contains no EXIF, so your location isn’t leaked when you share the photo. With “Keep EXIF data” ticked, the date taken, camera model and — if present — GPS location are copied into the JPG; the orientation tag is reset because the pixels are already rotated. EXIF is not added to PNG output.
Frequently asked questions
How do I make my iPhone take JPG instead of HEIC?
Go to Settings › Camera › Formats and choose “Most Compatible”. New photos are then saved as JPG. With Settings › Photos › “Transfer to Mac or PC” set to Automatic, photos are also converted when copied over a cable.
Are my photos uploaded to a server?
No. The conversion happens entirely in your browser and the files never leave your device.
How many photos can I convert at once?
There is no fixed limit; files are processed one after another. High-resolution photos can take a few seconds each, depending on your device.
Does converting reduce quality?
JPG is lossy, but at 90% quality the difference isn’t visible. Choose PNG if you want no loss at all.
Why won’t HEIC files open on Windows?
Windows needs separate HEIF and HEVC extensions to display HEIC. Instead of installing them, you can convert the photos to JPG here.
