HEIF to MP4 Converter

How to Convert HEIF to MP4 Online

1. Upload Your HEIF Files: Drag and drop, or click "+ Add Files" to select HEIF/HEIC photos from your device. Upload one image for a still-frame video, or multiple to assemble an ordered slideshow. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours.
2. Pick Merge Strategy and Duration: Choose "Merge images" to combine every HEIF into one continuous MP4, or "Video per image" to output a separate MP4 for each file. Set the per-image Duration (0.1s up to 10s) — three to five seconds is typical for slideshows.
3. Set Codec, Quality and Resolution (Optional): Pick a video codec (H.264 plays everywhere; H.265/HEVC matches the source compression; AV1 or VP9 for the web). Pick a Quality Preset (Very High recommended), or switch to target file size (%) or CRF for finer control. Pick a resolution preset (1080p, 1440p, 4K), keep original, or enter custom width/height. Choose a Background Color (Black, White, or 24 named colors) for letterboxing.
4. Convert and Download: Click "Convert" and download the MP4. No watermark, no sign-up, no per-file count limits.

Why Convert HEIF to MP4?

HEIF (High Efficiency Image File Format) is the ISO/IEC 23008-12 container Apple adopted as the iPhone camera default in September 2017 with iOS 11. A HEIF file is not just a single image — the spec stores image items, image sequences, bursts, and derived edits, all typically compressed with HEVC (H.265). MP4 is the universal video container that every browser, TV, social platform, and editor can play. Wrapping a HEIF stills sequence — or any HEIF photo set — into an MP4 unlocks playback everywhere HEIF still doesn't render natively.

• Social uploads that demand video — Instagram Reels, TikTok, YouTube Shorts, and Facebook Stories accept MP4 but reject HEIF entirely. A 10-photo HEIF gallery exported as a 30-second 1080p H.264 MP4 uploads cleanly to any of them.
• Windows and Android compatibility — Windows 10/11 needs the paid HEIF Image Extensions plus the free HEVC extension to view HEIF; many Android browsers still fail to decode HEIF inline. MP4/H.264 plays on every Windows install since Windows 7 and every Android device since 2010.
• Slideshows for events and client delivery — wedding, real-estate, and product photographers can stitch dozens of HEIFs into a 1-3 minute MP4 reel without opening Premiere or Final Cut, then drop it into a Google Drive folder for the client.
• Email and chat attachments — Gmail caps attachments at 25 MB and Outlook.com at 20 MB per message. A 1080p MP4 of ten photos at 3s each typically lands at 5-10 MB versus the same gallery zipped as HEIF.
• Archive of bursts and Live Photos — HEIF bursts hold dozens of frames; exporting as MP4 turns each burst into a short clip that's easier to scrub through than tapping each frame individually in Photos.
• Embedding in presentations — PowerPoint and Keynote happily import MP4 but choke on HEIF unless extra codecs are installed on every machine the deck plays on.

Frequently Asked Questions

Will a single HEIF photo convert to an MP4 video?

Yes — uploading one HEIF produces an MP4 that displays that single image for the duration you set (0.1s-10s). It's useful for reels-style posts that need a "video" upload format but only have one frame of content, or for stamping a still image with the audio-friendly MP4 container before adding music in another tool.

What happens to an animated HEIF or a HEIF image sequence?

The HEIF spec supports timed image sequences and cinemagraphs, but most HEIF files in the wild from iPhones are still images — the motion portion of a Live Photo is stored as a separate MOV file alongside the HEIC, not inside the HEIC. If you upload a true HEIF image sequence (e.g., from some Canon or Android bursts), this converter treats each frame as a slideshow input. To convert the MOV companion of an iPhone Live Photo to MP4, use MOV to MP4 instead.

What's the difference between HEIF and HEIC?

HEIF is the container standard (ISO/IEC 23008-12); HEIC is the.heic file extension Apple uses when that container holds HEVC-compressed images. Every.heic is a HEIF; not every HEIF uses.heic (some Android phones and Canon cameras use.heif). This converter accepts both — see HEIC to MP4 if your files have the.heic extension.

Can I keep the original resolution of my HEIF photos?

Yes. Leave the resolution preset on "Original" and the MP4 will be encoded at the source HEIF dimensions — typically 4032×3024 for iPhone main-camera shots or 8064×6048 for iPhone 14 Pro and later 48 MP captures. Note that 4K+ MP4 doesn't play back on every older device and quadruples file size versus 1080p downscaling.

Why is my HEIF slideshow MP4 larger than the source HEIFs combined?

HEIF is extremely compressed (HEVC stills target ~50% of JPEG size at equal quality). MP4 video — especially H.264 — has to encode many copies of each frame across the duration you set (typically 24-30 fps × 3 seconds = 72-90 encoded frames per still). Drop to H.265, lower the resolution to 720p, or shorten per-image duration to shrink the output.

Will the MP4 include any audio from a Live Photo?

No. The audio portion of a Live Photo lives in the companion MOV file, not the HEIC still. This tool builds the video from images only; the result is a silent MP4. If you need the audio, convert the.mov file separately and overlay it in a video editor like DaVinci Resolve or CapCut.

How long can my slideshow be?

There's no hard time cap. Practically, the longest dimension is total upload size — a 50-photo slideshow at 1080p H.264, 3 seconds each, runs 2.5 minutes and lands around 20-40 MB. For TikTok (10-minute cap) and YouTube Shorts (3-minute cap), keep slideshows under those platform limits.

Can I rearrange the photo order before converting?

Yes. Drag uploaded files in the queue to reorder them; the first file in the list becomes the first frame of the slideshow. Files are also processed in the order you uploaded them, so you can drop them in batches deliberately. To trim the resulting video later, see the Video Cutter.

Are my HEIF files uploaded to a server?

Files are processed in a temporary browser session and removed after conversion completes. There are no permanent uploads, no account is created, and the output MP4 downloads straight to your device. To shrink the result further, use Compress MP4; to make a GIF instead, see HEIF to GIF.
