PDFConvertersOnline.comHow to convert HEIC to JPG
- Tap Choose HEIC photos and pick the .heic files, or drag a whole selection onto the box.
- Leave JPG selected and adjust the quality slider if you want smaller files.
- Press Convert, then save each JPG or grab them all at once as a ZIP.
Why your iPhone saves photos as HEIC
Since iOS 11, iPhones store pictures in HEIF, a container format whose files end in .heic. Apple chose it because it keeps the same visual quality as JPEG in noticeably less storage, which adds up quickly when a phone holds thousands of pictures. On the phone itself you never notice: Photos, Messages and AirDrop between Apple devices handle HEIC without complaint.
The trouble starts when a photo leaves that world. Common places where a .heic file gets stuck:
- Windows PCs – older versions can't show HEIC at all, and newer ones often need the HEIF Image Extensions from the Microsoft Store before Photos will open it.
- Websites and upload forms – job portals, government sites, marketplaces and many online shops only list JPG and PNG as allowed types.
- Older photo editors, printers and photo kiosks that were built before HEIC existed.
JPG, by contrast, has been the default photo format for decades. Converting to it is the simplest way to make a picture readable by everyone.
What happens to your photos here
Decoding happens inside this browser tab. Your pictures are read from your disk or camera roll, turned into JPG in memory and handed back as a download; no copy travels to a server. Because HEIC is a demanding format to unpack, expect a few seconds per photo, a little more on older phones. A message on the progress screen tells you which picture is being opened, so a longer pause is normal and not a crash.
Some HEIC files hold more than one image, for example a burst or the still part of a Live Photo. The converter keeps the first (main) image. Camera details such as location and model are not copied into the new JPG, which is handy if you're about to post the picture publicly.
Choosing the JPG quality
The slider starts at 90%, which is visually indistinguishable from the original for normal viewing. Drop to around 75% if a form limits file size, or use Compress Image afterwards when you need to hit an exact number of kilobytes. Going higher than 90% mainly makes files bigger.
Stop the iPhone from creating HEIC files
If you'd rather get JPGs straight from the camera, open Settings → Camera → Formats and choose Most Compatible. New photos will then be saved as JPEG (and videos as H.264), at the cost of using more storage. Photos you already took stay HEIC, so they still need converting. Another option is Settings → Photos → Transfer to Mac or PC → Automatic, which lets the iPhone hand over compatible files when you copy pictures to a computer with a cable.

Frequently asked questions
Will converting HEIC to JPG lower the quality?
JPG uses lossy compression, so a tiny amount of detail is always rounded off. At the default 90% setting the difference is not visible on screen or in normal prints. The JPG will usually be larger than the HEIC file, because HEIC compresses more efficiently.
Why does my iPhone sometimes send JPGs anyway?
When you share or pick a photo in some apps, iOS may convert it to JPG automatically for compatibility. If the file you choose here is already a JPG, you can still convert it to another format or simply use it as it is.
Can I convert a whole album at once?
Yes. Select as many HEIC files as you like; they are converted one after another. With two or more photos you get a Download all (ZIP) button so you don't have to save them one by one.
Does this work on Windows without the HEIF extension?
Yes. The decoding code comes with the page, so Windows doesn't need any codec installed. The same goes for Chromebooks and Linux.
One photo shows an error. What now?
That file may be damaged, incomplete (for example an iCloud photo that was never fully downloaded) or use a HEIF variant the decoder doesn't support. The other photos in the batch are still converted; only the problem file is marked in the result list.
