Can FitKB open HEIC files directly?

It depends on the browser. Safari on iPhone and Mac can decode HEIC, so it works there. Chrome and Firefox on other systems usually cannot; convert the photo to JPG first.

Does HEIC to JPG conversion lose quality?

Very little at normal settings. Any loss is far smaller than the compression needed to meet a typical form limit.

How to Upload iPhone HEIC Photos to Forms That Want JPG

By FitKB · Updated November 11, 2026 · 2 min read

Quick answer

iPhones save photos as HEIC by default to save space, and many forms accept only JPG. Picking the photo through the photo picker in Safari usually converts it automatically. Otherwise, switch the camera to Most Compatible, or export a JPG copy, then compress it to the form's limit.

What HEIC is

HEIC (High Efficiency Image Container) is a modern photo format that Apple has used by default since iOS 11. It stores photos at about half the size of JPG at similar quality. The downside is compatibility: many websites, older computers and upload forms cannot read it.

Option 1: Pick the photo through the photo picker

When you tap an upload button in Safari and choose Photo Library, iOS usually hands the website a JPG copy. This is the simplest route and works with FitKB: tap the upload area, choose the photo, and the result is saved as JPG.

Option 2: Make the camera save JPG

Open Settings on the iPhone.
Tap Camera, then Formats.
Choose Most Compatible.

New photos are then saved as JPG. Photos you have already taken stay HEIC, and JPG photos take more storage.

Option 3: Transfer photos as JPG

If you copy photos to a computer with a cable, open Settings, tap Photos, and under Transfer to Mac or PC choose Automatic. The iPhone then converts photos to a compatible format during the transfer.

Option 4: Convert on a Mac or PC

Mac: open the photo in Preview, choose File, then Export, and pick JPEG as the format.
Windows: the Photos app can open HEIC once the HEIF Image Extensions are installed from the Microsoft Store; then use Save as and choose JPG.

Then meet the size limit

A converted iPhone photo is still 2 to 5 MB. Open it in a preset such as compress to 100 KB, or the home page resizer to type any limit.

How to tell whether a photo is HEIC

In the iPhone Photos app, open the photo and swipe up, or tap the info button; the format is shown with the camera details.
In the Files app or on a computer, look at the file extension: .heic or .heif means HEIC, .jpg or .jpeg means JPG.
If a form says the file type is not supported but the photo opens fine on your iPhone, it is very likely HEIC.

Why many forms still refuse HEIC

Upload forms check file types to make sure the systems that store and display the photos can read them. JPG has been readable everywhere for decades, while HEIC support is still uneven across browsers and server software, and some HEIC features are covered by patents. Until that changes, expect most government and exam portals to keep asking for JPG.
