Convert BMP to JPG

Turn a huge uncompressed bitmap into a small, shareable JPG — free, in your browser, with nothing uploaded.

Drag & drop your .bmp files here

One or many — nothing is uploaded.

On your device.Your photo is decoded by code running in this browser tab. It is never uploaded — you can watch the Network tab in your browser’s developer tools stay empty while it converts.

A BMP (Windows bitmap) stores every pixel uncompressed, which makes the files enormous — a single screenshot-sized bitmap can be tens of megabytes. Converting to JPG compresses the same picture down to a tiny fraction of that size, which is almost always what you want once a BMP needs to be emailed, uploaded, or stored.

The browser reads the bitmap and re-encodes it as a JPEG at your chosen quality. For an ordinary photo or screenshot the visual difference at a high setting is negligible, while the file shrinks dramatically. BMP files have no transparency to worry about, so nothing is lost there.

Drop one BMP or a batch and download them as a single .zip. Everything happens in this browser tab; the bitmap is never uploaded anywhere.

Frequently asked questions

Why are BMP files so large?
BMP stores every pixel uncompressed, so the size is roughly width × height × colour depth — many megabytes even for a modest image. JPG compresses it, which is why the file shrinks so much.
Is any quality lost converting BMP to JPG?
A little — JPG is lossy — but at quality 85–100 it’s essentially invisible, and the size saving over an uncompressed bitmap is so large the trade is almost always worth it.
Can I convert a batch of BMP files at once?
Yes — drop in as many as you like; each becomes a JPG and they download together as one {.zip}. All processed locally, nothing uploaded.
