BMP to JPG converter
Convert bulky BMP images to compact JPG — locally, no upload.
Convert BMP to JPG in your browser
BMP is an old, uncompressed image format — files are huge because every pixel is stored raw. Converting BMP to JPG shrinks the file dramatically, often by 90% or more, while looking the same, so it is easy to share, email or upload.
The conversion runs entirely in your browser: the BMP is decoded and re-encoded as JPG on your device, with no upload and no size limit beyond memory. You control the quality and can balance file size against sharpness.
JPG is ideal for photographic BMPs; for screenshots or graphics with sharp edges and text, convert to PNG instead to avoid compression artefacts. Either way, the original BMP never leaves your device.
Privacy by design
All processing happens inside your browser. Your files never reach a server — there is nothing to store, transmit or share.

Load not just one image but as many as you like — by drag & drop or multiple-select. imagenimble processes them one after another, locally in your browser, and packages the results as a single ZIP download. No upload, no account and no fixed limit — only your device’s memory caps very large batches. It is the quick way to convert or edit a whole folder in one go.
