Quick answer: To convert BMP to JPG, add the BMP file to the iHateFiles BMP to JPG converter and press Convert. The conversion runs in your browser, so the file is never uploaded, and it is free with no sign-up, watermark or size limit. BMP carries transparency and JPG cannot, so transparent areas are filled with a background colour you choose.
Should you convert BMP to JPG?
Do this for photographs, where JPG saves a great deal of space for a difference almost nobody can see. Keep the BMP if the image is a screenshot, a logo, or anything with text or hard edges in it.
BMP keeps everything, JPG does not
BMP stores the image exactly. JPG discards detail to save space, and the quality setting on this page decides how much. This is the right trade for photographs and the wrong one for screenshots and line art, where BMP edges stay crisp and JPG smudges them.
JPG cannot hold transparency
Any transparent area in the BMP has to become a real colour, because JPG has no alpha channel to record it. The background colour on this page is what those areas become. White suits most uses; pick the colour of the page it will sit on if you know it, because this cannot be undone afterwards.
Expect a much smaller file
A BMP of a photograph is routinely several times the size of the same picture as JPG. That saving is the reason to do this, and on a photograph it costs very little that anyone will notice.

What usually goes wrong
About the BMP. The file size surprises people. There is no compression to speak of, so the size depends only on the dimensions, not on how complicated the image is.
About the JPG. Re-saving a JPG repeatedly degrades it every time, because it re-encodes from the already damaged version. Edit from the original, and export to JPG once at the end.
How to convert BMP to JPG
- Add your BMP file. It is read from your disk and stays there.
- Check the settings. The output format is already set to JPG.
- Press convert and the JPG file is saved back to your device.
Questions
How do I convert BMP to JPG?
Open this page, add your BMP file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.
Is this BMP to JPG converter free?
Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.
Are my files uploaded anywhere?
No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.
Is there a file size limit?
No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.
Will converting to JPG lose quality?
JPG is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.
Can I convert several BMP files at once?
Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
