PNG to VOB Converter

PNG to VOB Converter

This tool turns a single PNG still image into a VOB (DVD Video Object) clip: the image is held on screen for a duration you choose, encoded as MPEG-2 video, and wrapped in the DVD-Video container so it can be used when authoring a DVD. There is no motion and no audio — it is one frozen frame repeated for the chosen length. Because VOB is a video format and PNG transparency has no equivalent on a DVD, any transparent areas are flattened against a solid background color (black by default). The usual reason to do this is to build DVD content from a still — a title card, a menu background, or a "please wait" / intro screen.

How to Convert PNG to VOB

1. Upload Your PNG File: Drag and drop your PNG onto the page or click "+ Add Files" to choose it.
2. Set the Image Duration: Choose how long the still is held on screen (the default is 5 seconds per frame) — this becomes the clip length.
3. Pick a Background Color and Quality Preset: Set the Background Color used where the PNG is transparent, and choose a Quality Preset (Very High is the default); optionally fix the Video resolution to a DVD size like 720×480.
4. Convert and Download: Click "Convert" and download the VOB. No sign-up, no watermark.

Frequently Asked Questions

Does the VOB keep my PNG's transparency?

No. A DVD-Video frame has no alpha channel, so transparency cannot survive the conversion. Any transparent or semi-transparent pixels are composited onto a solid Background Color — black unless you change it. If your graphic was designed to sit over something else, pick a background here that matches your intended DVD backdrop.

What resolution and frame rate should I use for a real DVD?

DVD-Video is fixed to 720×480 at 29.97 fps for NTSC (North America, Japan) or 720×576 at 25 fps for PAL (most of Europe, Australia). If you plan to burn the output to a playable disc, set the Video resolution to the size that matches your target region; a PNG at an arbitrary size may be rescaled or letterboxed by your DVD-authoring software otherwise.

Why is there no sound on the output?

This converter builds the clip from a still image only, so there is no audio track to carry. The VOB is video-only. If your DVD needs music or narration under the still, add the audio in your DVD-authoring or video-editing program after conversion, or start from a video that already contains the soundtrack.

Can I drop this VOB straight onto a DVD?

Not by itself. A working DVD needs the full VIDEO_TS structure — IFO and BUP navigation files alongside the VTS_xx_y.VOB video objects — which is built by DVD-authoring software, not by renaming a single file. Treat this output as a source clip you import into your authoring tool, where it becomes a title, menu background, or intro before the disc is burned.

How long can the clip be, and how big will the file get?

The length is whatever Image Duration you set. Because the frame never changes, MPEG-2 compresses a still very efficiently, so even a long hold stays modest in size; in our testing a 720×480 still held for 10 seconds produced a VOB well under a megabyte. Note that DVD-Video caps each .VOB at about 1 GiB, so very long holds are split across multiple objects by authoring tools.

Is VOB still the right target, or should I use MP4?

Use VOB only if your end goal is a physical DVD or DVD-Video folder structure. For anything that plays on a phone, browser, or smart TV, a modern container is a better fit — convert your still with PNG to MP4 instead. If you already have a VOB and need it to play off-disc, VOB to MP4 re-wraps it for general playback.

Are my uploaded files kept private?

Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
