Convert BMP to JPEG — free, private, in your browser
Decoded with browser decoder, encoded with MozJPEG — entirely on your device. No upload, no queue, no watermark.
Why convert BMP to JPEG?
Convert BMP (uncompressed windows bitmaps. huge files — almost always worth converting) to JPEG — JPEG's lossy compression makes files dramatically smaller. Drop files below: decoding and encoding run entirely in your browser via WebAssembly, so images are never uploaded to a server.
How to convert BMP to JPEG
- 1Drop your BMP files onto the tool above (or click to browse, or paste from the clipboard). Batches are fine.
- 2JPEG is pre-selected as the output. Adjust the quality slider — 80 is visually lossless for most photos. Optionally cap the maximum dimension to also downscale.
- 3Each file converts in your browser and shows its new size. Download files individually or grab everything as a ZIP.

Frequently asked questions
Is it safe to convert BMP to JPEG online?+
With EditItAll, your files are never uploaded: decoding and encoding run inside your browser using WebAssembly (the browser's built-in decoder to decode, Squoosh-grade codecs (MozJPEG, libwebp, libavif, libjxl, OxiPNG) to encode). The images stay on your device from start to finish, and the whole thing works offline once the page has loaded.
Will converting BMP to JPEG lose quality?+
JPEG is a lossy format, so re-encoding discards some information — at quality 80+ the difference is invisible for photos. Use the quality slider to choose the trade-off; nothing else in the pipeline degrades the image.
Is there a file size or count limit?+
No hard limits and no accounts — processing uses your own device's memory and CPU, so very large images are only constrained by your browser (multi-hundred-megapixel images may fail on low-memory devices). Batch as many files as you like; they are processed in sequence.
Can I convert JPEG back to BMP?+
Yes — use the JPEG to BMP converter, or just change the output format dropdown after dropping files.
