.avi (or .mp4/.mkv Xvid-encoded) file, or click "+ Add Files" to browse. Batch upload is supported — extract frames from several clips in one pass.00:01:23.500), or Multiple Screenshots to extract several frames spaced by interval, count, or framerate. Default is one frame at the midpoint.Xvid is a free, GPL-licensed MPEG-4 Part 2 (Advanced Simple Profile) codec released in 2001 — the open-source twin of DivX, typically packaged inside .avi containers. Most Xvid footage in circulation is legacy: ripped DVDs, early-2000s camcorder tape transfers, and YouTube downloads from before H.264 dominated. HEIF (ISO/IEC 23008-12, finalized in 2015) wraps HEVC-coded stills inside an ISOBMFF container, producing files roughly half the size of an equivalent-quality JPEG with optional 10-bit and 12-bit color depth. Pulling stills from Xvid into HEIF is the modern way to archive frames for an Apple-centric workflow without ballooning storage.
.avi deposition recording and hand off as HEIC; ISOBMFF stores the timestamp and original codec ID alongside the pixel data.| Property | Xvid (.avi) | HEIF (.heic) |
|---|---|---|
| Type | Video container with MPEG-4 ASP video | Still image (or image sequence) container |
| Codec / standard | MPEG-4 Part 2 ASP (Xvid implementation, GPL) | HEVC (H.265) inside ISO/IEC 23008-12 |
| Year finalized | MPEG-4 Part 2: 1999; Xvid 1.0: 2004 | ISO/IEC 23008-12: 2015 |
| Bit depth | 8-bit per channel (typical) | 8 / 10 / 12-bit |
| Stores | Motion video + audio | One still, a burst, depth maps, or auxiliary data |
| Native on iPhone | No (requires VLC/Infuse) | Yes (iOS 11+, default camera output) |
| Native on Windows | Yes with codec pack; built-in playback varies | Windows 11 22H2+ (built-in), Windows 10 needs free HEIF Image Extension |
| Browser display | Not for browser playback (download only) | Safari 17+ only; Chrome/Edge/Firefox do not render HEIC inline |

| Preset | Image Quality slider | Best for |
|---|---|---|

| Low | ~50% | Email-attachment size where detail matters less |
| Medium | ~65% | Balanced everyday stills |
| High | ~80% | Photo-library archival from SD-quality Xvid |

HEIF is the container standard (ISO/IEC 23008-12). HEIC is the specific HEIF profile that uses HEVC (H.265) compression and the .heic filename extension. Every HEIC is a HEIF, but HEIF can in theory carry other codecs (AV1 in AVIF, JPEG, etc.). Apple's HEIC files from iPhone are the same format you get from this tool — there's no quality or compatibility difference between the two extensions for the HEVC profile.
Yes. Xvid is a codec, not a container. Almost all Xvid video ships inside .avi, but the same codec also appears in .mp4 and .mkv. This page accepts .xvid extensions explicitly; if your file is .avi the AVI to HEIF page handles the same source files with identical options. The output is the still — the container of the input doesn't change which frames you can extract.
Yes. Choose Specific Frame under "Frame Selection" and enter the time in seconds (decimals supported). For a 23-minute Xvid clip, 1380.5 extracts the frame at 23:00.5. The tool seeks to the nearest decoded keyframe and decodes forward to the requested time, so accuracy is within one frame of the source framerate.
HEIF stores pixels with HEVC, which uses larger, variable-size coding blocks (up to 64x64 vs JPEG's fixed 8x8), better intra-prediction modes, and arithmetic entropy coding (CABAC) instead of Huffman. The Alliance for Open Media's tests and Apple's own published comparisons put HEIC at roughly half the size of JPEG at matched perceptual quality — sometimes more on smooth content like skies, less on noisy textures.
Windows 11 (version 22H2 and later) opens HEIC natively in the Photos app — no extra install. Windows 10 needs the free Microsoft HEIF Image Extension from the Microsoft Store; full hardware-accelerated HEVC decode also requires the paid HEVC Video Extension (~$0.99) or a graphics driver that ships its own HEVC decoder. If you need JPEG-everywhere compatibility instead, use Xvid to JPG.
Only Safari 17 and later renders HEIC inline. Chrome, Edge, Firefox, and Opera do not have native HEIF support as of 2026. If you're publishing a still to the open web, either convert through HEIF to JPG or use AVIF (which is HEIF's open-license cousin and has broad browser support).
Possibly. Xvid-in-AVI from older DVD rips or DV transfers is often interlaced (typically 480i59.94 or 576i50). The converter does not auto-deinterlace stills. If you see horizontal combing, run a deinterlace pass first by converting through Xvid to MP4 (which deinterlaces during transcode) and then extracting HEIF from that intermediate. For 100% progressive Xvid clips this is a non-issue.
The HEIF container will include creation timestamp and basic image metadata, but the source .avi file format itself carries very limited metadata (FOURCC, framerate, duration). Camera EXIF such as ISO, aperture, and GPS is essentially never present in Xvid AVI — those tags are an iPhone/DSLR thing, not a transcoded-video thing. The output stills get fresh creation dates from the conversion run.
AVIF (.avif) wraps AV1 inside the same ISOBMFF container HEIF uses, so it's structurally close but uses a royalty-free codec. AVIF gets full browser support (Chrome 85+, Firefox 93+, Safari 16+), HEIC gets only Safari. For Apple Photos workflows pick HEIF; for anything web-facing pick AVIF. The compression efficiency is a wash at typical photo quality — both beat JPEG by ~50%.
