Supports: BMP
A BMP is a single still image, so converting it to HEVC (H.265 video) does not create motion — it produces a silent video that holds that one picture on screen for a duration you choose. This walk-through shows how to do it, when it actually makes sense, and why HEVC is usually the wrong target for a single still.
.bmp onto the page or click "+ Add Files". With several bitmaps, pick Merge images to chain them into one clip or Video per image for a separate file each.This is the part people get wrong, so it is worth being precise. A BMP holds one frame of pixels and nothing else — no timeline, no audio, no animation. The conversion takes that single image and repeats it as the only frame of an H.265 stream for the duration you set. The result plays like a paused video:
.hevc file, since the extension names the H.265 video stream inside (the file itself is a Matroska container).If you want X, set the controls like this:
HEVC's whole advantage is inter-frame compression — it predicts each frame from the ones around it to shrink moving footage. A still image has no motion to predict, so none of that benefit applies. Worse, HEVC's intra-frame coding will re-compress your bitmap lossily, so a pristine uncompressed BMP comes out slightly degraded with nothing gained in detail. You also inherit HEVC's real-world downsides: slow encoding, patchy playback, and patent-licensing baggage (see the table). For one frame, those costs buy you almost nothing.
| Concern | What happens with BMP → HEVC |
|---|---|
| Detail gained | None — wrapping a still adds no information; H.265 intra-coding re-compresses it lossily |
| Motion compression benefit | None — there is no motion between frames to compress |
| Playback | The .hevc file is a Matroska container; VLC/mpv open it directly, but stock apps and extension-driven software may balk — renaming to .mkv helps |
| Encoding speed | Slow relative to H.264 for the same hardware |
| Licensing | HEVC is patent-encumbered (multiple pools: MPEG LA, Access Advance, Velos Media) |
| Better still-as-video target | BMP to MP4 — H.264 plays virtually everywhere |
Most people who land here do not actually need video at all. If your goal is just a smaller, shareable still, keep it an image: BMP to PNG is lossless and far smaller than an uncompressed bitmap, and BMP to JPG is smaller still for photos. If a platform genuinely demands a video file, BMP to MP4 is the safe choice — its H.264 codec plays on virtually every phone, browser, and social app, where an .hevc file — a Matroska container that stock apps rarely accept, holding a codec browsers rarely decode — frequently will not. Reach for HEVC only when a specific pipeline explicitly requires an H.265 .hevc file. To go the other direction and pull a frame back out of an H.265 file, see HEVC to MP4.
Most people who reach this page do not actually need video. Here is how the realistic outputs compare for a single bitmap.
| Target | Output | Opens / plays on | Best for |
|---|---|---|---|
| HEVC (this page) | Silent H.265 video (one still) | Needs an HEVC-capable player | A pipeline that explicitly requires H.265 |
| MP4 (H.264) | Silent video | Virtually every phone, browser, app | A still-as-video that plays anywhere |
| PNG | Lossless still image | Everything | A small lossless image or screenshot |
| JPG | Lossy still image | Everything | The smallest photo for sharing |
No. A BMP is a single still raster image with no frames, timeline, or audio of its own. The conversion holds that one image on screen for the duration you choose, so there is no motion, and because the source is an image the output is silent — the audio codec is not written at all. To get movement or sound you would need a video editor, not a format conversion.
No. Wrapping a still in HEVC adds no detail. HEVC's compression advantage comes from predicting one moving frame from another, and a single repeated frame has nothing to predict. Its intra-frame coding will actually re-compress your bitmap lossily, so an uncompressed BMP comes out slightly softer, not sharper, with no upside.
The .hevc file is actually a Matroska (MKV) container holding H.265 video, and two compatibility gaps stack against it: browsers generally don't play Matroska, and native HEVC decoding is patchy even inside friendlier containers. MKV-capable players such as VLC and mpv open it directly — seeking included — and renaming the file to .mkv helps software that judges by extension. If you need a still as a video that plays anywhere, convert BMP to MP4 instead — its H.264 codec is supported on virtually every device.
HEVC (H.265, standardized in 2013 by the JCT-VC group of ISO/IEC MPEG and ITU-T) is built to compress motion, encodes slowly, has patchy playback, and is patent-encumbered through several licensing pools. For one frame none of its motion-compression gains apply, so you pay all of HEVC's costs for none of its benefit. If you only need a smaller still, BMP to PNG or BMP to JPG is the right tool.
The Image Duration dropdown ranges from a single frame (1/60s, 1/30s, or 1/24s) up to 10 seconds per image. In our testing, a 1920×1080 BMP set to 5 seconds produced a short silent H.265 clip a few hundred kilobytes in size, since a static frame needs almost no data to repeat. For a true single frame to drop into an editing timeline, choose "1/30s"; for a slide meant to dwell on screen, choose 5–10 seconds.
For one frame, H.264 in an MP4 is almost always better. HEVC's efficiency comes from compressing motion between frames, and a single repeated still has no motion to exploit, so the size advantage over H.264 is negligible. Meanwhile MP4/H.264 plays on virtually every phone, browser, and app, while the Matroska-packaged .hevc file is far pickier about players (stock apps favor MP4). Unless a specific pipeline demands H.265, BMP to MP4 is the more compatible result for the same still.
Yes. Upload all the bitmaps and choose Merge images to chain them into a single clip, with each frame held for the Image Duration you set; pick Video per image instead to get a separate file for each BMP. The result is still silent, since images carry no audio. If you want smooth motion rather than a series of held stills, that requires a video editor — a format conversion only repeats each frame for its set duration.
