Since iPhone 7, Apple has saved photos in HEIC (High Efficiency Image Container) by default. HEIC delivers excellent quality at roughly half the file size of JPG — great for storage, but a problem when you want to share images on platforms like Twitter, Reddit, older CMS tools, or any service that simply doesn't accept the format. Converting to GIF is one way to get a universally supported image file that works everywhere.

That said, "HEIC to GIF" actually covers two very different scenarios, and the right method depends on what you're trying to accomplish.

HEIC to GIF: Two Different Use Cases

Before picking a method, decide which use case applies to you:

Static HEIC photo → GIF image. You have a regular HEIC photo and want to convert it to a GIF file — a single-frame, static image in a universally supported format. This is useful when a platform rejects HEIC uploads and you don't mind using GIF (though JPG or PNG are usually better choices for photos; more on that below).
iPhone Live Photo → animated GIF. Live Photos capture a short video clip (about 1.5 seconds before and after the shutter). Converting that motion to an animated GIF lets you share the "living" moment on any platform that supports GIF animation — messaging apps, social media, websites, email.

Method 1: Online Converter (Static HEIC to GIF)

The fastest way to turn a still HEIC photo into a GIF is to use a free online image converter. Because most converters don't offer a direct HEIC→GIF path, the cleanest two-step approach is:

Convert HEIC to JPG or PNG first (lossless intermediate).
Convert the resulting JPG/PNG to GIF.

You can do both steps in one place with Picovert's free Image Converter. Upload your HEIC file, choose GIF as the output format, and download — no account required, no software to install, and your files are never stored on the server.

Tips for online conversion:

Keep original HEIC files as your archive — GIF is lossy for photos (256 colors).
If the platform you're uploading to accepts JPG or PNG, prefer those over GIF for photographic images. GIF's 256-color palette causes noticeable banding on photos.

Method 2: iPhone Live Photos to Animated GIF

The most popular reason people search "HEIC to GIF" is actually to animate Live Photos. Apple provides two built-in ways to do this without any extra app:

Using the Photos App (Share Sheet)

Open the Live Photo in your iPhone's Photos app.
Tap the Share button (the box with an arrow).
Scroll down and tap Save as Animated GIF.
The GIF is saved to your Camera Roll and is ready to share.

Using the iOS Shortcuts App

If the "Save as Animated GIF" option doesn't appear on your device, use the built-in Shortcuts app:

Open the Shortcuts app and tap the + icon to create a new shortcut.
Add the action Make GIF.
Add a Save to Photo Album action after it.
Run the shortcut, select your Live Photo when prompted, and it saves as a GIF.

Third-party apps like GIPHY, ImgPlay, and Lively can also convert Live Photos to animated GIFs with more control over frame rate, speed, and loop settings — all available for free on the App Store.

Method 3: Mac Preview

macOS's built-in Preview app can open HEIC files natively (macOS High Sierra and later). Here's how to convert a static HEIC to a GIF-compatible image on Mac:

Open the HEIC file in Preview.
Go to File → Export.
Choose JPEG or PNG from the Format dropdown (Preview cannot export directly to GIF).
Save the file, then use an online GIF maker or Photoshop to convert to GIF.

Alternatively, open multiple HEIC frames in Preview, select all thumbnails in the sidebar, and export them as a PDF or image sequence, then feed that sequence into a GIF maker tool.

Method 4: Windows

Windows 10 and 11 don't support HEIC natively, but you can add support for free:

Open the Microsoft Store and search for HEIC Image Extensions (published by Microsoft). Install it for free.
Once installed, open your HEIC photo in the built-in Photos app.
Click the three-dot menu (···) and choose Save a copy.
Select JPEG as the format. (The Photos app on Windows doesn't export directly to GIF.)
Open the saved JPEG in an online GIF converter to complete the conversion.

If you prefer an all-in-one desktop tool, IrfanView (free, Windows) can open HEIC files after installing the HEIC codec and save directly to GIF format.

Why GIF Might Not Be the Best Choice for Photos

GIF was designed in 1987 for simple graphics — icons, logos, and short animations. Its 256-color limit is a serious drawback for photographic content:

Color banding: Photos have millions of colors; GIF reduces them to 256, causing visible gradients and banding, especially in skies and skin tones.
Large file sizes for photos: A photographic GIF can actually be larger than a comparable JPEG because GIF's compression isn't optimized for continuous-tone images.
No transparency support for partial pixels: GIF supports only binary (on/off) transparency, not the smooth edges that PNG offers.

If your goal is just to share an iPhone photo on a platform that doesn't accept HEIC, converting HEIC to JPG is almost always the better choice — smaller files, better color reproduction, and wider compatibility than GIF.

For animations specifically, WebP and MP4 offer far better quality and compression than GIF. A 5 MB animated GIF can often become a 500 KB MP4 with identical visual quality.

Convert Live Photo Video to GIF

If you've exported your Live Photo as a MOV or MP4 video (via the iOS Share sheet or AirDrop) and want to turn that video clip into an animated GIF, use Picovert's free Video to GIF converter. Upload the video, set the frame rate and duration, and download the GIF — all in your browser with no upload size restrictions.

To recap: for still photos, use an online image converter to go HEIC → GIF (or better yet, HEIC → JPG). For animated Live Photos, use the iOS Share sheet or Shortcuts app directly on your iPhone, or export the video and use a video-to-GIF tool for more control over the output.
