Short answer: To convert HEIC to JPG, drop your iPhone photos above, keep JPG selected and click Convert. Your photos are decoded in your browser, so nothing is uploaded, and the JPG copies open on Windows, Android and almost every website.
Your iPhone saves photos as HEIC to keep storage use low, and that is great until you try to use one somewhere else. Windows may show a blank thumbnail, a website may say the file type is not allowed, and a colleague's older software may not open it at all. Converting to JPG solves all of that. This page decodes HEIC directly in your browser, so the photos from your camera roll are never sent to anyone, and you can drop dozens at once.
What is HEIC, and why did Apple choose it?
HEIC is a picture format built on the same video technology that makes streaming efficient. Since iOS 11, iPhones and iPads use it by default because it keeps a photo at similar visual quality in a noticeably smaller file than JPEG. The trade-off is compatibility. Many websites, email programs, print shops and older computers still expect JPG, which is why a photo can look perfect on your phone and fail on the first form you try to upload it to.
When should you convert?
Convert before uploading to a government portal, a marketplace listing, a school system or a job site, since these often accept only JPG or PNG. Convert before sending photos to someone who uses Windows or an older Android phone. Keep the original HEIC files in your library as your archive, because they hold the most detail, and use the JPG copies for sharing. Your phone can also be set to share as most compatible, but converting afterwards works for photos you already have.
What problems can happen, and how do you avoid them?
If a picture appears rotated, check the original on your phone, since the converter follows the orientation stored in the file. Live Photos become a single still image, and the short video part is not kept. Portrait mode depth data is dropped. Very large panoramas can take a few seconds each because decoding happens on your device. Location and camera details are removed from the JPG, which is useful when you post photos online.
Sharing a whole trip
After a holiday you may have hundreds of HEIC photos. Convert them in batches: a computer can take around a hundred at a time, a phone fewer. Add a rename pattern such as holiday-{n} to number the pictures in order, which keeps the album tidy when you upload it. Large photos take a moment each because decoding happens on your own device, so keep the tab open until the list shows the green checks. If you only need a smaller copy for messaging, open Advanced options and set a width such as 1600 pixels before converting.
Questions people ask
Why do my iPhone photos not open on my PC?
They are saved as HEIC, which many Windows programs cannot read without an extension. Converting to JPG makes them open everywhere.
Do Live Photos keep their motion after conversion?
No. You get one still image. The short video that goes with a Live Photo is not part of the JPG.
Are my photos uploaded while converting?
No. HEIC decoding runs in your browser, so photos from your camera roll stay on your device.
Can a converted photo still reveal where it was taken?
Not from ManyFormat. Re-encoding drops the camera details and the GPS location stored in the HEIC file, so the JPG you share carries no hidden map position.
Why do some of my iPhone photos arrive as JPG and others as HEIC?
Apple converts automatically in some sharing paths and not in others, depending on the app, the receiving device and your settings. When in doubt, convert the photos yourself before you send or upload them.
