VOB to AVIF Converter

How to Convert VOB to AVIF Online

1. Upload Your VOB File: Drag and drop or click "+ Add Files" to select a .vob file from your DVD's VIDEO_TS folder. Multiple files are processed in batch with the same settings.
2. Pick a Frame and Quality Preset: Choose Specific Frame with a time in seconds (e.g., 12.5) to grab a single still, or Multiple Screenshots to pull frames at a chosen interval. Set Quality Preset to Very High (recommended), High, Medium, or Low — VOB uses MPEG-2 at roughly 4–9 Mbps for NTSC DVDs, so going below Medium rarely helps.
3. Resize and Set DPI (Optional): Pick a Preset Resolution (720p, 1080p, 1440p, up to 4320p), enter a custom Width / Height in pixels or percent, or keep the original 720×480 (NTSC) / 720×576 (PAL) DVD frame. Set DPI (default 300) when you need print-ready stills.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no watermark, no sign-up — and you get one AVIF per extracted frame.

Why Convert VOB to AVIF?

VOB (Video Object) is the DVD-Video container carrying H.262/MPEG-2 video, AC-3 or DTS audio, subtitles, and menu data, stored as 1 GiB chunks inside the VIDEO_TS folder. AVIF (AV1 Image File Format) is the still-image sibling of the AV1 video codec, designed to deliver photographic quality at roughly half the bytes of JPEG. Pulling stills from a DVD into AVIF gives you archive-grade thumbnails, web-ready posters, and printable frames without dragging around the original 4.7 GB disc image.

• DVD archiving and chapter thumbnails — Extract one representative frame per chapter from a ripped DVD and store the whole set as AVIFs. A 90-minute movie's chapter thumbnails fit in a few hundred kilobytes instead of the megabytes JPEG would need.
• Web-ready DVD screenshots — AVIF is supported in Chrome 85+, Firefox 93+, Edge 121+, and Safari 16.4+ — about 94% of global browsers. Serving DVD stills as AVIF (with a WebP/JPEG fallback) cuts page weight on review sites, fan wikis, and home-media catalogs.
• Replacing IFO/BUP-era poster art — DVDs from the early 2000s often shipped with low-bitrate menu art baked into the VOB. Extract a clean still at the moment the menu rests, then encode at Very High quality for a sharper poster than the disc itself provides.
• Preservation of old home video — Mini-DV camcorders that authored straight to DVD produced VOBs at 720×480 (NTSC) or 720×576 (PAL). Saving key frames as AVIF keeps the archive 50% lighter than JPEG without further generation loss.
• HDR-aware stills (when source supports it) — AVIF supports 10- and 12-bit depth and BT.2020 color, so if your VOB has been remuxed from an HD source you can preserve a wider gamut than 8-bit JPEG allows.
• Reference frames for editing — Pull stills at exact timestamps to use as match frames in DaVinci Resolve or Premiere when restoring a DVD project; AVIF's higher dynamic range survives subsequent grading better than JPEG.

Frequently Asked Questions

Why does my AVIF look soft compared to the DVD playback?

DVD video is interlaced at 720×480 (NTSC) or 720×576 (PAL) with non-square pixels and a 4:3 or 16:9 display aspect ratio. When we extract a frame, we deinterlace to progressive and apply the correct pixel aspect ratio so the still looks right on a square-pixel display. If you upscale beyond the source resolution, the AVIF encoder can't reconstruct detail that isn't in the MPEG-2 stream — keep "Keep original" or 576p/480p for the sharpest result.

Can I extract every frame from a VOB at once?

Yes — use the Multiple Screenshots option with an interval of 1 second (or a custom rate). A 90-minute NTSC VOB at 29.97 fps contains roughly 162,000 frames; pulling every one is rarely useful, so most users pick one frame per second, one per chapter, or every 30 seconds for scrubbing previews. Files are named with their timestamp so you can re-assemble the sequence.

Should I convert VOB to AVIF or to JPG/PNG?

For web and archive use, AVIF wins on size: independent benchmarks (including Netflix's published research) put AVIF roughly 50% smaller than JPEG at matched quality. Pick VOB to JPG if you need compatibility with software that doesn't yet read AVIF (older Photoshop, some CMS uploaders), VOB to PNG for lossless extraction, or VOB to WebP for a middle ground with broader (~96%) browser support.

Does VOB-to-AVIF preserve audio or subtitles?

No. AVIF is a still-image format and cannot carry audio or subtitle tracks. The AC-3, DTS, or LPCM audio multiplexed into the VOB is dropped at extraction. If you need the soundtrack, convert the VOB to MP4 for the full A/V container, then export a frame separately.

What about animated AVIF — can I get a short clip instead of a still?

This page outputs still AVIFs. Animated AVIF is in the spec and supported by recent browsers, but for clip-style exports a GIF or WebP animation is usually a better fit because of broader player support. Use the multiple-screenshots option here, or convert to GIF/WebP from the format menu.

Why is the 1 GiB VOB limit relevant?

DVD-Video specifies that each .vob file in the VIDEO_TS folder is capped at 1 GiB so it can be read on file systems that don't support larger files (FAT32 historically). A feature-length DVD is therefore split across VTS_01_1.VOB, VTS_01_2.VOB, etc. Upload each VOB segment separately if you want frames from a specific reel; the timestamps you enter are relative to that segment, not the whole movie.

What DPI should I pick for printing a DVD frame?

300 DPI (the default) produces a print-ready file at the native 720×480 frame size — roughly a 2.4" × 1.6" print. That's appropriate for a magazine column or a contact sheet. For larger prints, upscale the resolution preset and accept some softness, or run the AVIF through a dedicated upscaler before printing. Below 150 DPI the print will visibly soften on glossy paper.

Will the AVIF still play if my browser is older than Safari 16.4?

Safari 16.0–16.3 had partial AVIF support (still images yes, some color profiles iffy); Safari 15 and earlier won't render it at all. For broad-compatibility delivery, encode an AVIF for modern browsers and a fallback MP4 to AVIF workflow plus a JPEG/PNG sibling — the <picture> element will pick the best format the browser supports.

Is there a file-size limit on uploads?

Yes — single uploads are capped at 1 GB, which matches the per-segment ceiling of a DVD VOB so a single VTS_*.VOB always fits. Files are processed on our servers and deleted automatically a few hours after conversion.
