VOB to PNG Converter

How to Convert VOB to PNG Online

1. Upload Your VOB File: Drag and drop or click "+ Add Files" to select VOB files from your DVD's VIDEO_TS folder. Batch upload is supported, so you can queue multiple VOBs at once.
2. Pick Quality Preset and Resolution: The default is "Very High" quality at 768p. For archival captures, pick "Highest" and a "Preset Resolution" of 1080p or 1440p. For thumbnails, drop to "Medium" or "High" with 480p or 720p. You can also enter exact pixel dimensions under "Width (Keep aspect ratio)" or "Width x Height".
3. Choose Specific Frame or Multiple Screenshots (Optional): Use "Specific Frame" with a Time (seconds) input to grab a single still from a known timestamp, or "Multiple Screenshots" to extract a sequence at a chosen interval. Leave at defaults to grab the first frame.
4. Convert and Download: Click "Convert" and download the resulting PNG. Files are processed server-side and deleted automatically after a short retention window — no sign-up, no watermark, no app install.

Why Convert VOB to PNG?

VOB (Video Object) is the container DVD-Video uses inside the VIDEO_TS folder, holding MPEG-2 Part 2 video plus AC-3, DTS, MPEG, or PCM audio. NTSC discs encode at 720×480 and PAL at 720×576, often in anamorphic 16:9 — meaning the stored pixels are stretched on playback. Extracting a still as PNG gives you a lossless raster image you can crop, retouch, or print without re-compressing the original frame.

• Recover photos from DVD slideshows — Tools like Windows DVD Maker, iDVD, and Sony Picture Motion Browser burned photo slideshows to DVD as VOB. Pulling frames back to PNG is often the only way to recover the originals when the source JPGs are lost.
• Frame-accurate screenshots from old DVDs — A PNG capture preserves crisp edges, text overlays, and menu graphics far better than a JPG export, which adds blocky artifacts around hard edges.
• Print-ready stills — At 720×576 anamorphic stretched to ~1024×576, a single DVD frame is roughly a 3.4 × 1.9 inch print at 300 DPI. Upscale to 1080p or 1440p for larger prints.
• Compositing and chroma key work — Editors pulling background plates from VHS-to-DVD transfers need lossless PNG frames rather than re-encoded JPGs so After Effects and Resolve can key cleanly.
• Subtitle, menu, and overlay extraction — Subtitle stream graphics, animated menus, and chapter thumbnails are easiest to isolate as PNG frames before further editing.
• Archival and forensic captures — Researchers digitising legal evidence DVDs or news archives need reproducible PNG stills with timestamps preserved in the filename sequence.

VOB vs Other Video Containers

PNG Quality Preset Quick Guide

PNG is lossless, so the preset mainly affects the compression filter strategy and resulting file size — not the visual fidelity of the decoded image.

Frequently Asked Questions

Why does my VOB-to-PNG output look horizontally squished?

DVD video is stored anamorphically: a 16:9 widescreen disc squeezes the picture into a 720×480 (NTSC) or 720×576 (PAL) frame. If you extract a raw frame, faces will look narrow. Upscale to a 16:9 preset like 1080p or 1280×720 under "Width x Height" and the converter will stretch the frame back to the intended aspect ratio.

Can I grab a frame at a specific timestamp in the VOB?

Yes. Open "Advanced Options", select "Specific Frame", and enter the time in seconds. The converter seeks to that point and writes a single PNG. For longer captures, use "Multiple Screenshots" to extract frames at fixed intervals — useful when you don't know exactly where the moment you want lives.

My DVD has several files: VTS_01_1.VOB, VTS_01_2.VOB, VTS_01_3.VOB. Which do I upload?

DVD authoring tools split the main title into chunks of roughly 1 GB so the original FAT32 file systems could handle them. Each VTS_01_N.VOB is a continuous segment of the same title — upload whichever segment contains the frame you want. If you're not sure, upload the largest one (often _1) which usually contains the feature's start.

Should I use JPG or PNG for DVD frames?

PNG if you plan to edit, retouch, key, or print the image — it's lossless and preserves text, line art, and menu graphics cleanly. JPG if you just need a small web preview. For most archival and editing workflows the answer is PNG, since the source MPEG-2 frame is already lossy and you don't want to add another lossy step. If you need JPG instead, use VOB to JPG.

What's the difference between extracting a VOB frame here vs. taking a VLC screenshot?

VLC's "Take Snapshot" captures whatever frame is on screen at the moment you click — interlaced fields and all, often at the display's resolution rather than the source. The converter here decodes the actual MPEG-2 frame and writes it at the source resolution (or your chosen preset), giving you a clean, deterministic still you can reproduce by timestamp.

Will the converter deinterlace fields from an interlaced DVD?

Most consumer DVDs from the late 1990s and 2000s are interlaced (480i/576i). The extraction pipeline decodes the MPEG-2 stream and writes a single progressive PNG; for sports, news, or old TV captures with fast motion you may see comb artifacts. Try grabbing an adjacent frame, or convert the VOB to a progressive MP4 first and then capture from the progressive output.

Are my uploaded VOB files private?

Yes. Files are processed on our servers and deleted after a short retention window. No conversions are kept, indexed, or shared. There are no watermarks or sign-up requirements.

My VOB is encrypted (CSS) and won't process. What now?

Commercial DVDs are typically CSS-encrypted. Most online tools — including this one — cannot decode CSS streams, and bypassing CSS may also be illegal in your jurisdiction. For your own home-recorded DVDs, the VOBs are unencrypted and convert without issue. If you need a different output, try VOB to MPG for the raw MPEG-2 stream or VOB to GIF for animated previews.

Can I extract every frame as a numbered PNG sequence?

Use "Multiple Screenshots" with a 1-frame interval to approximate this. DVDs run at 29.97 fps (NTSC) or 25 fps (PAL), so a 60-second clip yields roughly 1,500-1,800 PNGs — be mindful of the resulting output size. For longer batch sequences across many VOB segments, a desktop tool like FFmpeg or VirtualDub may be a better fit.
