MTS to BMP Converter
MTS is the AVCHD container your Sony, Panasonic, or Canon camcorder writes, holding H.264-compressed 1080p video. BMP is Microsoft's Windows bitmap — an uncompressed, lossless raster format. This tool decodes one frame (or a batch of frames) from your MTS clip and saves it as a BMP still, giving you a pixel-exact bitmap with no additional compression applied on top of the source video.
MTS (AVCHD) Format at a Glance
| Property | Value |
|---|---|
| Format | MTS / M2TS — AVCHD (Advanced Video Coding High Definition) |
| Introduced | 2006, co-developed by Sony and Panasonic |
| Video codec | H.264 / MPEG-4 AVC |
| Typical resolution | 1080i / 1080p and 720p |
| Container | MPEG-2 Transport Stream (.mts on camera, .m2ts on disc) |
| Audio | Dolby AC-3 or linear PCM |
| Best for | Recording HD footage on AVCHD camcorders |
| Plays in browsers | No native support — needs conversion to MP4/WebM |
BMP Format at a Glance
| Property | Value |
|---|---|
| Format | BMP — Windows Bitmap (device-independent bitmap) |
| Origin | Microsoft, for the Windows and OS/2 graphics subsystem |
| Compression | Typically none — pixel data stored uncompressed |
| Quality | Lossless container (stores the decoded frame exactly) |
| Common bit depth | 24-bit (true color, 16.7 million colors) |
| 1080p frame size | About 6.2 MB at 24-bit (1920 × 1080 × 3 bytes) |
| Best for | Pixel-exact stills for editing or analysis pipelines, Windows tooling |
| Plays in browsers | Limited — no native <img> support in most browsers |
How to Convert MTS to BMP
- Upload Your MTS File: Click "+ Add Files" to drag and drop your MTS clip, or select it from your device. Multiple files are accepted.
- Pick the Frame: In Advanced Options, choose Specific Frame to grab one still at a chosen Time (seconds) — the input accepts millisecond precision, so
2.100lands on 2 seconds and 100 ms. Choose Multiple Screenshots to pull a sequence of frames, delivered together as a ZIP. - Set Quality and Resolution (Optional): Use the Quality preset and Image resolution controls if you want to downscale the output. Leave them at default to keep the source frame's full dimensions.
- Convert and Download: Click "Convert" and download your BMP. No sign-up, no watermark.
Frequently Asked Questions
Does converting MTS to BMP add any compression loss?
No. BMP stores the decoded frame uncompressed, so the conversion itself adds no new loss — it preserves the decode exactly. The one caveat: the source MTS is already H.264-compressed video, so any detail that codec discarded during recording is gone before extraction. BMP can't restore what H.264 never kept; it just captures the pixels as they decode, without throwing any more away.
Why is the BMP so much larger than a JPG of the same frame?
Because BMP applies no compression. A 1080p frame at 24-bit color is roughly 6.2 MB as a BMP (1920 × 1080 × 3 bytes of raw pixel data). The same frame saved as JPG can be a few hundred kilobytes because JPEG drops data the eye is unlikely to notice. If file size matters more than a pixel-exact bitmap, convert MTS to JPG instead.
Should I use BMP, PNG, or JPG for an extracted frame?
For most people, PNG is the better choice — it is lossless like BMP but compressed, so you get the same pixel-exact frame at a much smaller size and with native browser support. Pick BMP specifically when a Windows tool or an editing/analysis pipeline expects an uncompressed bitmap. Pick JPG when you just need a shareable still and want the smallest file.
How do I grab a frame from an exact moment in the clip?
Choose Specific Frame in Advanced Options, then type the timestamp into the Time (seconds) field. The field takes a decimal, so 12.500 extracts the frame at 12.5 seconds. For a burst of stills across the clip, switch to Multiple Screenshots, which returns the frames packaged as a ZIP.
What bit depth does the output BMP use?
The output is a standard 24-bit true-color BMP, which stores 16.7 million colors with one byte each for red, green, and blue. That matches the color range of the decoded H.264 frame, so no color information is lost in the handoff from video to bitmap.
Will the BMP open everywhere?
BMP opens in Windows Photos, Paint, and virtually every desktop image editor (Photoshop, GIMP, IrfanView). Web browsers and many phone galleries have only partial BMP support, so if you plan to post the still online or view it on mobile, PNG is the safer, smaller format.
How are my files handled, and how long are they kept?
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.
I want to keep the video, not extract a still — what should I use?
To convert the whole clip to a widely playable format instead of grabbing a frame, use MTS to MP4. Going the other direction — building an MTS clip from bitmap stills — is handled by BMP to MTS.
