JPG to BMP Details
JPG to BMP turns the JPG files you already have into BMP. No account, no extension to install, no settings to hunt through.
JPG is the long-standing photo format: lossy compression, no transparency, and support in every viewer worth mentioning. BMP stores pixels as they are, with no practical compression standing in the way.
Step by step
Three moves make up the whole flow: drop the file, convert, download. The detail is below.
- Drag your JPG files onto the upload area, or click it and pick them from the file dialog.
- Each queued file shows its name and size. Remove what you do not need; one round handles 20 files at most.
- The convert button rewrites the selected file as BMP; the batch button repeats that for every JPG file in the queue.
- Rename the output in the queue field before downloading; the extension is set to BMP for you.
- Downloading is the last step: the BMP file goes to your browser folder and no copy stays on the server.
Technical details
Here is the technical side of the conversion in short:
- Accepted input: JPG (jpg, jpeg), up to 24 MB per file.
- The result is written as BMP and written with no compression applied.
- The queue carries 20 files at a time, and each file travels in its own request.
- Neither format carries transparency, so the background behaves exactly as it did before.
- BMP applies no compression, so the output file is clearly larger than the source.
- JPG was already compressed with loss, so writing BMP losslessly protects what is left instead of restoring detail.
- Do not count on metadata surviving: whether EXIF and ICC data travel depends on the engine handling the file, so keep anything critical elsewhere.
When to choose this tool
This conversion earns its place when an existing JPG file has to land somewhere that asks for BMP. Legacy Windows tooling, a handful of printer drivers and software that wants raw pixels still ask for BMP. Files grow several times larger than the alternatives, and in exchange nothing is discarded. JPG is the long-standing photo format: lossy compression, no transparency, and support in every viewer worth mentioning.
BMP works against you if the goal is archiving or smaller files. Choose WebP or AVIF output when size matters, and stay here only when raw pixels are required.
Quick tips
- For larger sets, work in groups of 20; the queue survives as long as you keep the tab open.
- Renaming outputs in the queue keeps your downloads folder readable once several BMP files land there.
- BMP is written losslessly, so saving again does no damage and the file works as an archive copy.
- Open the BMP file afterwards and check edges and colour gradients, and keep the JPG source where it is.
Data and privacy
Your file travels over HTTPS, is processed during that single request and comes back as the download itself. It is never written to a public directory, nothing is kept once the response is sent, and the download is marked as non-cacheable.
