HEIF to Video Converter

How to Convert HEIF to Video Online

1. Upload Your HEIF Files: Drag and drop or click "Add Files" to select one or more .heif images. Batch upload is supported — drop a whole folder of bursts, timelapse stills, or screenshots and the page handles them in upload order.
2. Pick an Output Format: Choose from 32 video targets — MP4 (universal H.264), MKV, MOV, WebM, AVI, HEVC, AV1, WMV, FLV, MPG, MPEG, MPEG2, MTS, M2TS, TS, VOB, OGV, 3GP, 3G2, ASF, AVCHD, DIVX, F4V, M2V, M4V, MJPEG, MXF, RM, RMVB, SWF, WTV, and XVID. MP4 plays everywhere; MOV is best for Apple ecosystem editing in Final Cut or iMovie; VOB targets DVD authoring.
3. Set Merge Strategy and Image Duration: Pick "Merge images" to stitch every uploaded HEIF into a single video, or "Video per image" to render one video per file. Image Duration ranges from 1/60s per frame (60 fps timelapse) up to 10 seconds per frame (slow slideshow). 1/24s and 1/30s match standard cinema and broadcast frame rates.
4. Tune Quality, Resolution, and Background, then Convert: Quality Preset offers Highest, Very High (Recommended), High, Medium, Low, Very Low, and Lowest. Resolution can keep the original HEIF dimensions, snap to a preset (4320p down to 144p, plus social presets like 1080×1080 and 1080×1920), or take an exact width × height. Background Color fills any letterboxing when aspect ratios differ. Click Convert and download — files process on our servers, no sign-up, no watermark.

Why Convert HEIF to Video?

HEIF (High Efficiency Image File Format, ISO/IEC 23008-12) became iPhone's default capture format in iOS 11 (September 2017) and is used on iPhone 7 and later, recent iPads, and Apple Vision Pro. The format was designed from day one to hold image sequences with timing metadata — Apple's WWDC 2017 session 513 calls out two intended uses for that timing: capture time (a burst) and suggested display time (a slideshow). Turning a stack of HEIFs into a real video file is the natural next step when you want to share, edit, or play that sequence somewhere outside the Apple Photos app.

• Burst photos to playable clips — iPhone burst mode captures up to 10 frames per second. Stitching those frames at 1/10s per image plays the sequence back at full burst speed in any video player.
• Slideshows for non-Apple viewers — Friends and clients on Windows, Android, or smart TVs often can't open HEIF directly. An MP4 slideshow with 3-5 seconds per image plays on every device made in the last decade.
• Timelapses from interval shots — Drop 24 HEIFs taken one minute apart and render at 1/24s per frame; you get a one-second cinema-rate timelapse. 240 frames at 1/24s gives ten seconds of footage representing four hours of real time.
• Social media verticals — Use the 1080×1920 preset for TikTok / Instagram Reels / YouTube Shorts, or 1080×1080 for square Instagram feed posts. The Background Color control fills the bars when your HEIFs aren't already vertical.
• DVD and broadcast delivery — VOB and MPEG2 outputs feed straight into DVD authoring tools; MXF, AVCHD, MTS, and M2TS match camcorder and edit-suite ingest workflows.
• Archive Live Photo stills as motion — Live Photos store a still HEIF plus a paired MOV. Render the HEIFs together as one video to keep the visual sequence even when you can't preserve the.mov sidecars.

Frequently Asked Questions

Why convert HEIF to video instead of GIF or animated WebP?

Video formats give you real audio support, hardware-accelerated playback, and far better compression for sequences over a few seconds. A 30-frame burst rendered to MP4 at H.264 is typically a few hundred kilobytes; the same frames as a GIF are usually 5-20× larger because GIF is limited to 256 colors and has no inter-frame prediction. If the sequence needs to be tiny and play silently inline (chat reactions, email signatures), use HEIF to GIF or convert images to GIF instead.

How does Image Duration interact with the resulting frame rate?

Image Duration is the on-screen time per HEIF; the encoder sets the video's frame rate so each image gets exactly that duration. 1/24s per image yields a 24 fps file, 1/30s yields 30 fps, 5 seconds per image yields a 0.2 fps file. For smooth interpolation between stills you'd need a separate motion tool — this converter holds each frame for the exact duration you set without blending.

Will Live Photos transfer as motion?

A Live Photo is two files: a HEIF still and a paired QuickTime .mov clip. This converter sees the HEIF only, so the result is the still image rendered for your chosen Image Duration. To keep the captured motion you need the.mov sidecar, which Photos can export via Share → Save as Video, or you can run a batch through MOV to MP4 afterwards.

Why is my MP4 letterboxed or has black bars?

Output resolution and input HEIF aspect ratio don't always match. A 4032×3024 iPhone HEIF (4:3) rendered into a 1080×1920 vertical preset (9:16) leaves bars top and bottom. Either change Resolution to "Keep original," pick a preset that matches the source ratio, or use Background Color to make the padding white / brand-colored / blurred-friendly instead of plain black.

Should I pick H.264 (MP4), HEVC, or AV1?

H.264 inside MP4 is the safest default — every browser, phone, smart TV, and editor supports it. HEVC (H.265) is roughly 40-50% smaller at the same visual quality but playback support is uneven outside Apple devices and recent Android. AV1 is even more efficient but encode time is slow and decode is limited to recent hardware (2020+ Intel/AMD/Apple silicon, recent Android). Pick H.264 unless you specifically need the smaller files and control the playback environment.

What's the difference between "Merge images" and "Video per image"?

Merge images concatenates every uploaded HEIF into one video file in upload order — the typical slideshow / timelapse workflow. Video per image renders a separate clip for each input HEIF — useful when you want N independent looping clips, animated wallpapers, or single-frame stock for an editor's bin. The two modes share all the other settings (duration, quality, resolution).

Can I add music or captions to the slideshow?

Not in this converter — it renders silent video from your HEIFs. Take the rendered MP4 into iMovie, CapCut, DaVinci Resolve, or Premiere to add an audio track, titles, or transitions. Most editors will treat your output as a normal video clip on the timeline.

What's the largest sequence I can convert in one job?

There's no fixed cap published — files are uploaded and processed on our servers, so the practical limit is upload size and connection speed. For very large batches (thousands of frames), split the job into chunks (e.g., 500 frames each) and concatenate the resulting MP4s in an editor afterwards. Higher Quality Preset and 4K resolutions take longer to process than 1080p Medium.

Does HEVC inside MP4 play on Windows by default?

Not on a stock Windows install. Windows 10 and 11 ship without an HEVC decoder; users either pay for the Microsoft "HEVC Video Extensions" app or install the free "HEVC Video Extensions from Device Manufacturer" variant if their OEM bundles it. If you're sharing files with a mixed audience, stick to H.264 in MP4 — or render both versions and let recipients pick. For the still-image side, see HEIF to JPG for maximum compatibility.
