About converting BMP to JPG
BMP (.bmp) files can be converted to JPG entirely in your browser — no software to install, no file upload, and no account required. The conversion runs on the browser's own Canvas API directly on your device.
Technical comparison
| BMP | JPG | |
|---|---|---|
| Category | image | image |
| Compression type | Uncompressed (occasionally simple RLE) | Lossy (DCT-based) |
| Typical file size | Very large — essentially uncompressed pixel data | Small — a fraction of an equivalent PNG for photographic content |
| Transparency support | Rare (v4/v5 support alpha, but rarely used in practice) | No |
How to convert BMP to JPG privately
Every step below runs on the browser's own Canvas API inside this browser tab. Your .bmp file is never uploaded to a server — there's no network request carrying it anywhere.
Add your BMP file
Drag and drop, or click to select, a file (.bmp). It's read straight from disk into browser memory — no upload step exists.
Convert locally
FreePrivateConvert converts it to JPG using the browser's own Canvas API, entirely within this browser tab.
Download the result
Save your converted .jpg file. It only ever existed in this tab's memory — closing the tab without downloading discards it completely.
Convert BMP to JPG with ffmpeg (command line)
Prefer the terminal? This page uses your browser's built-in image engine; the equivalent ffmpeg command is:
ffmpeg -i input.bmp -q:v 2 output.jpg- -i input.bmp
- Your BMP file.
- -q:v 2
- JPEG quality 2 on a 2-31 scale (lower is better; 2-3 is visually lossless).
- output.jpg
- The JPG file to create. ffmpeg picks the container from this extension.
Don't have ffmpeg installed? You don't need it: use the converter at the top of this page. It runs this conversion on your own device, and your file is never uploaded.
FAQ
- Is my file uploaded anywhere?
- No. Your file is read and processed inside this browser tab and never leaves your device. You can confirm it in your browser's developer tools: the Network tab shows no upload.
- Does converting BMP to JPG reduce quality?
- JPG is lossy, so the image is re-encoded at 92% quality: visually very close to the original for photos, but sharp text, line art and flat colours can show slight artifacts. Transparent areas become white.
- Is there a file size limit?
- Yes: 500MB per file. There's no account and no limit on how many files you convert.
- What's the difference between BMP and JPG?
- BMP (Bitmap) and JPG (Joint Photographic Experts Group) store data differently. BMP: uncompressed (occasionally simple RLE). JPG: lossy (DCT-based). JPG is the standard lossy format for photographs — small file sizes achieved by discarding detail the eye is less sensitive to.
- Why convert BMP to JPG?
- Common uses for JPG: Digital photographs; Web images where transparency isn't needed; Email attachments where size matters. DCT-based compression is highly efficient specifically for photographic, continuous-tone content.
- What MIME type does a .jpg file use?
- image/jpeg, the standard type for Joint Photographic Experts Group.
- What is the ffmpeg command to convert BMP to JPG?
- Run: ffmpeg -i input.bmp -q:v 2 output.jpg. This page does the same conversion with your browser's built-in image engine, so you don't need to install ffmpeg.
