DivX to BMP Converter

Convert DivX to BMP Online

Grab a single frame from a DivX video and save it as a Windows Bitmap (BMP) — an uncompressed, pixel-exact still that opens natively in Paint, legacy Windows imaging apps, and machine-vision tools. DivX is a lossy MPEG-4 Part 2 codec, so the frame you pull already carries the video's compression; BMP just stores those decoded pixels verbatim without adding any further loss. Files upload over an encrypted connection, process on our servers, and are deleted automatically after a few hours — no sign-up, no watermark.

How to Convert DivX to BMP

1. Upload Your DivX File: Drag and drop, or click "+ Add Files" to select one or more DivX clips (the .divx or .avi carrying the DivX codec). Batch uploads are supported.
2. Pick Frame Selection: Choose Specific Frame and enter a timestamp in the Time (seconds) field — decimals work, so 2.100 lands at 2 seconds 100 milliseconds. Or choose Multiple Screenshots to extract a numbered sequence at a set interval.
3. Set Image Resolution and Quality (Optional): Under Image Resolution, keep the source size, scale by Resolution Percentage, pick a Preset Resolutions value, or type exact Width x Height. The Quality preset dropdown controls fidelity before the frame is written to bitmap; resolution is the main size lever because BMP is largely uncompressed.
4. Convert and Download: Click Convert. A single-frame job returns one BMP; a multi-screenshot job returns a numbered sequence packaged for download.

BMP vs PNG vs JPG for a Video Frame

BMP gives you raw, predictable pixels, but the files are large. For a still that's lossless yet far smaller, PNG is usually the better pick; for an everyday image to share, JPG is smaller again. Pick BMP only when a downstream tool specifically needs uncompressed bitmap data.

Frequently Asked Questions

How large will the BMP file be?

A 24-bit 1920x1080 frame is about 6.2 MB (1920 x 1080 x 3 bytes plus a small header), and a 4K (3840x2160) frame is near 24 MB — BMP stores every pixel without compression. Multi-screenshot jobs multiply that fast. To shrink output, lower the Resolution Percentage, or use DivX to PNG for a lossless still that's typically a quarter to a third of the BMP size.

Will the frame look the same as the video?

It matches what your player shows, but not necessarily the encoder's original source. DivX is MPEG-4 Part 2 ASP and uses chroma subsampling, so color is reconstructed at decode time; the RGB written to BMP is mathematically the decoded frame. If you also drop Resolution Percentage below 100%, the resampling adds correct-but-not-pixel-identical interpolation. For exact decoded pixels, keep the original resolution and 24-bit depth.

Can I extract a frame at an exact timestamp?

Yes. Choose Specific Frame under Frame Selection and type the time into Time (seconds). Decimals are supported — 5.25 pulls the frame at 5 seconds 250 milliseconds, and the closest decoded frame to that time is returned. In our testing, a 2.100 request on a 25 fps clip returned the frame at roughly the 52nd frame, exactly where that timestamp falls.

How do I get one BMP per second instead of a single frame?

Pick Multiple Screenshots instead of Specific Frame and set the interval to 1 second. The converter walks the clip start to finish at that cadence and outputs a numbered BMP sequence. To match the source frame rate, set the interval close to 1 / framerate (about 0.04 s for 25 fps, 0.033 s for 30 fps).

Why is the output BMP and not the smaller PNG I expected?

BMP is uncompressed by design — that is the format, not a setting. If you wanted a lossless still without the bulk, you picked the wrong target: DivX to PNG gives the same pixel-for-pixel quality at a fraction of the size, and DivX to JPG is smaller still when minor lossy compression is acceptable.

Are my uploaded files kept private?

Files travel over an encrypted (TLS) connection, are processed on our servers, and are deleted automatically a few hours after the job finishes. There is no sign-up, no watermark on the output, and files are never shared or made public.
