MOV to AVIF Converter

How to Convert MOV to AVIF Online

1. Upload Your MOV File: Drag and drop or click "+ Add Files" to load .mov video — typically QuickTime / iPhone recordings (HEVC or H.264) or ProRes masters from Final Cut Pro and DaVinci Resolve. Batch is supported — drop several clips and process them in one queue.
2. Pick a Frame Selection Mode: Choose Specific Frame to grab one AVIF still at a chosen Time in seconds (e.g. 12.5 for the frame 12.5s into the clip). Choose Multiple Screenshots to extract a sequence and set the capture rate — every 0.1s (10 fps), 0.2s, 0.5s, or every 1, 2, 3, 5, 7, or 10 seconds for sparser sampling. Each captured frame is encoded as its own AVIF still.
3. Set Quality and Resize (Optional): Pick an Image Quality Preset (Highest, Very High, High, Medium, Low, Very Low, Lowest) or target a specific file size in KB / MB / percentage. Toggle Lossless Yes for pixel-perfect frames at larger size. Choose a Resolution Preset (144P, 360P, 480P, 576P, 720P, 1080P, 1440P, 2160P / 4K, 4320P / 8K), scale by percentage, or set custom width × height in pixels.
4. Convert and Download: Click Convert. Frames decode and encode in your browser session and download individually or as a ZIP — no sign-up, no watermark, no upload to a third-party server.

Why Convert MOV to AVIF?

MOV is Apple's QuickTime container — the default capture format on every iPhone since iOS 11 and the master format in Final Cut Pro, DaVinci Resolve, and Premiere Pro. Inside a .mov you usually find HEVC (H.265) frames from a modern iPhone, H.264 frames from older devices, or ProRes for editing masters. AVIF (AV1 Image File Format) is the still-image cousin of the AV1 video codec, encoding a single decoded frame with compression that is typically 50-70% smaller than JPEG at matching quality, with native HDR and 10-bit support that JPEG cannot carry. Pulling AVIF stills from MOV is the modern way to publish poster frames, thumbnails, and HDR stills from iPhone or pro-camera footage.

• HDR stills from iPhone HEVC recordings — iPhone 12 Pro and later record HDR (HLG / Dolby Vision) into MOV. JPEG only carries 8-bit SDR; AVIF preserves 10-bit color and the highlight detail you'd otherwise crush by re-encoding to JPEG. This matters for sunsets, screen recordings of HDR content, and any clip where the brightest highlights or deepest shadows carry information.
• Web-optimized poster frames from QuickTime masters — A 1080p AVIF poster is typically 30-80 KB vs 200-500 KB for the equivalent JPEG. Across a video gallery with hundreds of cards, that's the difference between Largest Contentful Paint passing or failing Core Web Vitals on 4G.
• Thumbnail extraction from ProRes editing masters — ProRes MOV files are huge (gigabytes per minute) but carry the cleanest source. Pulling AVIF stills from a ProRes master gives you marketing thumbnails and contact-sheet stills without re-encoding the master itself.
• Open-graph and Twitter card images for video portfolios — Modern crawlers (Chrome, Edge, Safari 16+, iOS 16+) decode AVIF natively. Smaller share-card images preview faster on slow links and reduce CDN egress, which compounds across thousands of social shares.
• Frame-accurate documentation from screen recordings — QuickTime Screen Recording exports as MOV. Pulling AVIF stills at specific timestamps gives you UI documentation shots that are sharper than JPEG and 4-6x smaller.
• AI / vision pipelines that prefer modern formats — AVIF retains 10-bit color depth and lossless mode, useful for ML preprocessing where 8-bit JPEG quantization would discard signal in shadow areas of dim iPhone footage.

If you need lossless print-quality stills instead of compressed web stills, use video to PNG. For broadest legacy compatibility (every email client, every CMS), video to JPG is still the safest pick. To convert the MOV itself to a more web-friendly playable video, see MOV to MP4.

Frequently Asked Questions

Does this produce animated AVIF or single-frame AVIF stills?

This converter produces single-frame AVIF stills — one image per extracted frame. Use Specific Frame for one timestamp (one still) or Multiple Screenshots at a chosen capture rate to get a sequence (one AVIF per captured frame, downloaded as a ZIP). For an animated looping output from MOV, use MOV to GIF or MOV to WebP — animated AVIF tooling is still narrowly supported and most CMSes treat AVIF as a still format. MConverter is the well-known animated-AVIF converter; XConvert focuses on the still-image workflow that most CMSes actually consume.

Will the AVIF preserve HDR from my iPhone recordings?

If the source MOV carries HDR metadata (HLG on iPhone 12 Pro and later, or Dolby Vision on iPhone 12 Pro and later in the appropriate mode) and you keep the quality preset at Very High or higher, AVIF can preserve 10-bit color and the wide gamut. JPEG is 8-bit SDR only — extracting HDR iPhone video to JPEG visibly clips highlights. For critical HDR work verify the AVIF in a 10-bit-capable viewer such as Chrome on a P3 display or Safari on a recent iPhone.

Are HEVC (H.265) MOVs from iPhone supported on the input side?

Yes. iPhones since iOS 11 default to HEVC inside a .mov container ("High Efficiency" in Camera settings). The decoder reads HEVC-in-MOV directly and pulls frames the same way it reads H.264-in-MOV. No need to transcode the source first. ProRes (the editing-master variant exported from Final Cut Pro or DaVinci Resolve) is also supported, though large ProRes masters take more browser memory to decode.

Will my browser actually display the AVIF?

Yes in Chrome 85+ (August 2020), Firefox 93+ (October 2021), Safari 16+ / iOS 16+ (September 2022), Edge 121+ (January 2024), and Opera 71+. Roughly 96% of global browser sessions decode AVIF as of 2026. For the remaining sessions (mostly older Safari / Samsung Internet), serve a JPEG fallback via <picture><source type="image/avif">...</picture>.

Can I extract just one frame at a specific timestamp?

Yes — pick Specific Frame in step 2 and enter the Time in seconds (12.5 means 12.5s into the clip). The decoder seeks to that exact timestamp and writes one AVIF. Useful for grabbing an iPhone screen-recording moment, a chapter-marker still from an editing master, or a poster frame for a portfolio.

How big will my AVIF be vs the original screenshot from QuickTime Player?

A 1080p MOV frame typically lands around 30-80 KB at the High preset, vs 200-500 KB for the same JPEG and 2-5 MB for a lossless PNG. QuickTime Player's "Copy" and "Save Frame As" outputs are lossless PNG by default, so AVIF at High is roughly 30-100x smaller than QuickTime's native frame export. A 4K (2160P) AVIF still is usually 150-300 KB compared to 0.8-2 MB JPEG.

How does AVIF compare to WebP for MOV frame extraction?

AVIF wins on compression efficiency (typically 20-40% smaller than WebP at matched quality) and on HDR / 10-bit support, which matters for iPhone HDR clips. WebP wins on encode speed and on broader CMS / older-Safari support. For modern sites targeting Core Web Vitals, AVIF is the better pick; if you need to support iOS 15 or earlier, MOV to WebP is safer.

How many AVIF stills will I get from a Multiple Screenshots run?

Multiply duration by capture rate. A 60-second MOV at "1 second per frame" produces 60 AVIFs; at 0.1s (10 fps) it produces 600. A 4K iPhone clip at 10 fps for a minute can hit 30-80 MB total even in AVIF — start with 1 fps or 0.5 fps and refine downward only if needed.

Will my files be uploaded to your servers?

Conversion runs locally in your browser session — files don't go to a third-party storage layer for processing. Output AVIFs download directly to your device. No sign-up, no watermark, no file count cap. Competitors like MConverter cap free uploads at 100 MB per MOV; XConvert's practical ceiling is your device's available memory, which matters for multi-gigabyte ProRes masters.
