About this tool
BMP to JPG, in the browser and without an upload. BMP files are enormous - a single phone photo can run past 20 MB, and BMP being an uncompressed Windows format that stores every pixel at full size is exactly why that happens. Files usually come out noticeably smaller, because JPG compresses much harder than BMP. JPG is the format almost every camera, phone and website has understood for thirty years, and jPG is a lossy format, so a small amount of detail is discarded. At the quality this tool uses that is invisible on a photograph, but fine text and sharp edges - screenshots especially - can soften slightly. Everything happens locally. Your BMP files never leave the device, so there is no file-size limit and no waiting for a server to get to you.
How to use this tool
- Add your BMP filesClick the box or drag BMP images onto it. Nothing is uploaded - your browser reads the files directly.
- Let it convertEach image is decoded and re-encoded as JPG on your device. A large batch takes a moment; nothing is queued on a server.
- Download your JPG imagesSave them one at a time, or take the whole batch as a single ZIP.
Key features
- Converts BMP to JPG without uploading anything.
- Batch conversion - drop a whole folder and convert it in one pass.
- No sign-up, no watermark and no file-count limit.
- Works offline once the page has loaded.
- Shows the before and after size of every file, so you can see what the conversion cost or saved.
Common uses
- Getting BMP images into a document, presentation or email that refuses to embed them.
- Opening a BMP in software that only accepts JPG.
- Preparing BMP images for a platform that rejects the format on upload.
- Archiving BMP originals in a format you will still be able to open in ten years.
- Converting a batch of BMP files handed over by a client or a colleague.
Tips for better results
- Convert from the highest-quality BMP you have, not one that has already been resized or re-saved.
- Batch the whole folder in one pass - converting one file at a time is the slow way to do this.
Mistakes to avoid
- Renaming the file extension by hand instead of converting. That changes the name, not the data, and the file simply fails to open.
- Expecting JPG to repair a low-quality BMP. Conversion changes the container, never the pixels already inside it.
Supported formats
- BMP
- JPG
