What "HEIC to MP4" Actually Means

There is no video hidden inside a still HEIC file, so converting one to MP4 is not a format swap — it is building a short video out of one or more photos. Knowing which of the two things you want saves a lot of confusion.

A still HEIC has no motion to extract

A regular iPhone photo saved as .heic is a single frame — there is no clip inside it. To get an MP4, the photo has to be shown on screen for a few seconds and encoded as video. That is what this tool does: it turns one photo, or a stack of them, into a slideshow.

Several photos become one shareable clip

Drop in a handful of HEIC photos and they play one after another as a single MP4. This is the format TikTok, Instagram Reels, and Stories expect — a vertical video file — rather than a folder of images an app may not accept or may reshuffle.

Live Photos are a separate case

The 1.5 seconds of motion in an iPhone Live Photo does not live in the HEIC — it sits in a paired .MOV file that iOS keeps alongside it. If real motion is what you're after, you need that .MOV, not the .heic. This tool builds slideshows from the still frames; a dedicated Live Photo path is planned.

Ways to Turn HEIC Photos Into a Video, Compared

You can build the slideshow in a phone editing app, upload the photos to a cloud converter, or encode them in-browser here. What each route costs you:

Method	Install Needed	Many Photos	Speed	Privacy	Ease of Use	Best For
Phone video editor (CapCut, iMovie)	Install Needed:App install	Many Photos:Yes	Speed:Fast, but manual	Privacy:Local, varies by app	Ease of Use:Full control, more steps	Best For:Music, transitions, captions
Upload-based online converters	Install Needed: No	Many Photos:Sometimes — with limits	Speed:Depends on upload speed	Privacy:Photos sent to a server	Ease of Use:Easy	Best For:Occasional one-off use
Photos app "export as video"	Install Needed:Built-in (iPhone)	Many Photos:Limited	Speed:Fast	Privacy:Local	Ease of Use:Easy but inflexible	Best For:A quick clip from memories
This browser-based converterRecommended Recommended	Install Needed: No	Many Photos:Yes — up to 20	Speed:Runs on your CPU	Privacy:Photos never leave your device	Ease of Use:Drop, arrange, create	Best For:A quick, private slideshow to post

A note on what "slideshow" means here: each photo is held on screen for the seconds you choose and encoded as H.264 frames — there are no transitions, zoom, or music in this first version. If you want those, build the clip in a video editor. If you just need your HEIC photos as one MP4 you can upload, this is the shortest path.

How to Convert HEIC to MP4 Online

Three steps, no account, no install. Decoding and video encoding both run inside your browser with WebAssembly and WebCodecs, so your photos are never uploaded.

Add your HEIC photos in order

Drag in one photo or up to twenty. They play top to bottom, so arrange them the way you want the video to run — use the up and down arrows to reorder, or the X to drop one.

Set seconds per photo and video shape

Pick how long each photo stays on screen (1 to 5 seconds) and the shape: 9:16 for TikTok, Reels, and Stories, 1:1 for a square feed post, or 16:9 for landscape. A photo that doesn't match the shape sits on a blurred version of itself by default, or solid black or white bars if you prefer.

Create and download the MP4

The video is encoded on your device — you'll see it progress photo by photo. When it finishes, preview it inline and download a standard .mp4 that uploads straight to any social app.

How the Slideshow Is Built

The output is a plain, widely compatible MP4 — H.264 video, no audio — encoded to specifications that social apps accept without re-processing surprises.

Full HD, 30 frames per second, silent

Every video renders at 1080p on its long side and a steady 30fps, which is what TikTok, Reels, and Stories are tuned for. There is no soundtrack: a HEIC photo carries no audio, and adding music is a separate job best done in the app you post from.

Runs on your CPU, not your upload speed

Both the HEIC decode and the H.264 encode happen in your browser. A twenty-photo video takes as long as your device takes to encode it — no waiting on a slow upload, and no queue behind other people's files on a shared server.

Up to 20 photos, no watermark, no sign-up

Combine as many as twenty HEIC photos into one clip, as often as you like. Nothing is stamped onto the video, there is no account wall, and no daily limit. The cap exists to keep encoding fast on phones, not to push an upgrade.

HEIC to MP4 — Frequently Asked Questions

Common questions about turning HEIC photos into an MP4 video — Live Photos, video length, sound, aspect ratios, and how the conversion runs privately in your browser.

Does this pull the motion out of my Live Photo?

No — and it's worth understanding why. An iPhone Live Photo is stored as two files: a still .heic image and a separate .mov clip that holds the 1.5 seconds of motion, paired by an internal identifier. The .heic on its own has no video in it. This tool builds a slideshow from the still frame, so the result is your photo shown for a few seconds, not the Live Photo's movement. To keep the actual motion you need the paired .mov file. A dedicated Live Photo (.mov to .mp4) path is on the roadmap.

How long will my video be?

Total length is simply the number of photos multiplied by the seconds-per-photo you pick. Ten photos at 3 seconds each makes a 30-second video; four photos at 5 seconds makes 20 seconds. The tool shows the running total as you add photos and change the timing, so you can match a platform's limit before you encode.

Can I add music to the video?

Not in this tool. A HEIC photo has no audio track, so the MP4 comes out silent. That's deliberate: TikTok, Reels, and Stories all let you add a soundtrack after you upload, and their in-app music is what the algorithm favors anyway. If you want music baked into the file itself, drop the MP4 from here into a video editor and add audio there.

Which aspect ratio should I choose?

Pick 9:16 (1080×1920) for TikTok, Instagram Reels, and Stories — that's the full-screen vertical shape those feeds use. Choose 1:1 (1080×1080) for a square post in the main Instagram or Facebook grid. Use 16:9 (1920×1080) for YouTube or anywhere landscape video is expected. If a photo doesn't fill the chosen shape, it's centered with black or white bars rather than cropped, so nothing important gets cut off.

What fills the space when a photo doesn't match the video shape?

By default, a blurred, zoomed copy of the photo itself — the same look Instagram and CapCut use. The whole photo stays sharp and centered while the leftover space blends into a soft, out-of-focus backdrop instead of hard bars. If you'd rather have clean edges, switch the Background option to solid black or white. Either way the photo is never cropped — it's centered and scaled to fit, so nothing important is cut off. A photo that already matches the shape you picked fills the frame edge to edge, with no background showing at all.

Is the HEIC to MP4 conversion really private?

Yes. Both steps — decoding the HEIC and encoding the MP4 — run entirely inside your browser using WebAssembly and the browser's built-in WebCodecs video encoder. Your photos are never sent to HeicToPng or any third party. This matters more for video than for a single image: a slideshow often strings together personal moments, and uploading those to a stranger's server just to stitch them isn't a trade most people would make when the whole thing can happen locally.

What video format and quality do I get?

A standard .mp4 file using H.264 video (the codec every phone, browser, and social app understands), rendered at 1080p on the long side and 30 frames per second, with no audio. Because a still photo doesn't change frame to frame, the file stays small for its length — the encoder spends almost no data on unchanging frames. The result uploads to any social platform without conversion warnings.

How many photos can I add, and why the limit?

Up to 20 photos per video. The cap is about speed, not upselling: encoding happens on your own device, and each second of video is a batch of frames the encoder has to process, so a very long slideshow would tie up a phone for a while. Twenty photos keeps the wait reasonable on most hardware. If you need a longer video, encode two clips and join them in a phone editor.

The video is taking a while to create — is that normal?

On a phone, yes, a little. Video encoding is heavier than converting a single image because the tool produces 30 frames for every second of video and encodes each one. A short slideshow finishes in a few seconds on a laptop; a full 20-photo video on an older phone can take longer. The progress readout moves photo by photo so you can see it working. Keep the tab in the foreground while it runs.

It says my browser can't encode video — what now?

The tool needs the browser's WebCodecs H.264 encoder, which almost every current browser has: Chrome, Edge, Safari (Mac and iPhone), and desktop Firefox all work. The one common exception is Firefox on Android, which ships without an H.264 encoder. If you hit the message there, open the page in Chrome or Samsung Internet on the same phone and it will work.

Can I reorder the photos before making the video?

Yes. After you add photos they appear in a numbered list in the order they'll play. Use the up and down arrows on each row to move a photo earlier or later, and the X to remove one. The order in the list is exactly the order in the finished MP4, so arrange them before you hit create.

Does it work with .heif files too, or only .heic?

Both. HEIC and HEIF are the same underlying format — HEIC is just Apple's name for HEIF images — so the tool decodes .heic and .heif identically and puts either into the slideshow. You can mix both in one video.
