What Is a JPG to BMP Converter?

A JPG to BMP converter decompresses your JPG images into raw, uncompressed BMP files. BMP stores every pixel verbatim with no compression at all — the maximum-fidelity option when a workflow demands untouched bitmap data.

The conversion happens entirely in your browser. No upload, no limits — just instant, private conversion.


Every Format You Might Need

Convert between all major formats freely — no restrictions, no limits.

JPG / JPEG

Why Convert JPG to BMP?

Some workflows want raw pixels: embedded systems, industrial printers, certain scientific tools, and older Windows software expect BMP specifically. Because BMP has no compression, there is no encoder variance — what you write is exactly what any reader sees.

It is also a useful intermediate format when you need guaranteed-lossless handoff between tools.

Zero compression — raw pixel data
No encoder or decoder variance
Required by some legacy systems
Simple, well-documented structure

Frequently Asked Questions

BMP stores every pixel uncompressed — roughly 3 bytes per pixel plus headers. A 12-megapixel photo becomes about 36 MB.
No — the JPG's compression artifacts are permanent. BMP just guarantees no further loss from that point on.
Technically yes via alpha bitfields, but support is inconsistent across readers. Treat BMP as opaque in practice.
Only when a specific tool or system requires it. For every other purpose, PNG offers the same losslessness at a fraction of the size.
Never. All processing happens on your device. Your files never touch our servers.
