JPG to BMP Converter
Drop a JPG file below and get a BMP back in seconds. BMP is lossless, so nothing is lost beyond what was already baked into the JPG. No upload, no sign-up, no watermark.
Why use this tool
Why BMP?
BMP (Windows Bitmap) is an uncompressed Windows bitmap — large, but still required by some legacy software, embedded systems and print workflows.
What's wrong with JPG?
JPG can't hold transparency, and every re-save loses a little quality.
How to convert JPG to BMP
- Upload — drag your JPG file(s) onto the box, click to browse, or paste from the clipboard.
- Adjust — the output format is already set — optionally pick a background colour for transparent areas.
- Download — grab each BMP individually, or all of them at once as a ZIP.
Frequently asked questions
Will I lose quality converting JPG to BMP?
No. BMP is lossless — the converted image is pixel-for-pixel identical to what your browser decoded from the JPG file.
Can I convert several JPG files at once?
Yes. Drop as many files as you like — each one is converted individually and you can grab them one by one or all together as a ZIP.
Why is the BMP so much bigger?
BMP stores every pixel uncompressed — a 1920×1080 image is always about 6 MB. That's normal; only use BMP when a specific program requires it.
Is this tool free?
Yes — every tool on ConvertPicto is completely free, with no account, no watermark and no file limits. The site is supported by ads.
Are my images uploaded to a server?
No. ConvertPicto runs entirely inside your browser using the Canvas API. Your files are read locally, processed on your device and never sent anywhere — we don't even have a server that could receive them.
Does it work on my phone?
Yes. The site is fully responsive and works in any modern mobile browser (Chrome, Safari, Firefox, Edge). Processing large images is naturally slower on a phone than on a laptop.
