Need help?Convert BMP to MP4 Online
Turn a Windows bitmap (.bmp) into an MP4 video clip that holds your still image on screen for as long as you choose. There is no motion — the output is the same picture displayed for a set duration — which is exactly what you need when a platform like Instagram, YouTube, or a digital-signage screen accepts a video file but rejects a raw image. You control how long the frame is shown, the output resolution, and the background color used to pad non-16:9 images.
How to Convert BMP to MP4
- Upload Your BMP File: Drag and drop or click "+ Add Files" to load one or more
.bmpimages. With several files, choose Merge images to chain them into one clip or Video per image to get a separate MP4 for each. - Set the Image Duration: Open Advanced Options and pick Image Duration — how long the still is held (e.g. "5 seconds per frame"). This is the length of the resulting clip for a single image.
- Pick Resolution and Background Color: Use the resolution control (Keep original, Preset Resolutions, or Fixed Resolutions) to size the frame, and set Background Color (default Black) to fill the bars when your image aspect ratio does not match the chosen frame.
- Convert and Download: Click "Convert" to get your MP4. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.
How Long to Hold the Frame — Image Duration Guide
BMP stores a single still, so the only "timeline" in your MP4 is how long that one frame is displayed. The right duration depends on where the clip is going.
| Use case | Suggested duration | Why |
|---|---|---|
| Instagram feed / Reels placeholder | 3–7 seconds | Short autoplay loops; very short clips can be skipped before the image registers |
| YouTube intro card or static upload | 5–10 seconds | Long enough to read a title card; YouTube requires a video file, not an image |
| Digital signage / lobby screen | 8–10+ seconds | Static slides are meant to dwell so passers-by can read them |
| Looping background / placeholder | 1–5 seconds | Kept short because the clip is typically set to loop in the player |
| Single frame for editing timelines | 1/30s or 1/60s (one frame) | Drops the image in as a true single frame to extend or freeze elsewhere |
Frequently Asked Questions
Will the MP4 have any motion or just a static image?
Just a static image. A BMP is a single still raster picture with no frames or timeline of its own, so the conversion holds that one image on screen for the duration you set. There is no panning, zooming, or animation — if you need a moving "Ken Burns" effect, that requires a video editor, not a format conversion.
How long can I make the clip, and what frame rate is used?
The Image Duration dropdown ranges from a single frame (1/60s, 1/30s, or 1/24s) up to 10 seconds per image. Holding one still for several seconds does not require a high frame rate — a static frame looks identical at any rate — so longer durations keep the file small. To get a clip longer than the listed maximum, you can extend it afterward in a video editor.
What video codec does the MP4 use, and will it play everywhere?
The MP4 is encoded with H.264 (AVC) by default, which is the most broadly supported video codec on the web — caniuse reports roughly 96.6% global browser support, and it plays natively on virtually every phone, smart TV, and social platform. That is why MP4/H.264 is the safe choice when a site demands video but you only have a still image.
My BMP is not 16:9 — why are there black bars, and can I change them?
Because a square or portrait bitmap cannot fill a widescreen frame without distortion, the converter pads the empty space rather than stretching your image. The fill color comes from the Background Color option (Black by default; White and other presets are available). Alternatively, set the resolution to Keep original so the video frame matches your image's exact dimensions and no padding is added.
Can I combine several BMP images into one MP4 slideshow?
Yes. Upload multiple .bmp files and choose Merge images; each still is shown for the Image Duration you set, played back to back as a single clip. Choose Video per image instead if you want one separate MP4 per file. In our testing, ten BMP stills merged at 5 seconds each produced a single 50-second MP4.
Should I convert BMP to MP4, or would another format be better?
Convert to MP4 only when the destination specifically needs a video file. If you just want a smaller, more portable still image, convert BMP to PNG (lossless, transparency-capable) or BMP to JPG instead — both are far smaller than an uncompressed bitmap. For a short animated loop rather than a held still, BMP to GIF is the better target. Already have a JPG or PNG you want as video? Use JPG to MP4 or PNG to MP4.
