About the JPG to BMP Converter

Upload one or more JPG photos and get uncompressed BMP files back instantly — some older software, embedded systems and printer or hardware tools still expect the plain BMP format rather than a compressed one. Nothing is uploaded anywhere — the conversion runs in your browser.

BMP stores every pixel uncompressed as 24-bit colour, so the file size depends only on the dimensions — roughly width × height × 3 bytes, plus a tiny header. A 12-megapixel photo therefore becomes a BMP of about 36 MB, which is expected rather than a bug, and is why BMP is mainly used where software specifically requires it.

Examples

JPG to BMP examples

3 worked examples

01

A full-HD photo

A 1920×1080 JPG of 1007 KB becomes a 5.93 MB BMP — 1920 × 1080 pixels × 3 bytes each, with no compression at all.

02

A product photo

A 2000×1500 JPG product photo of 313 KB becomes an 8.58 MB uncompressed BMP, ready for older software that only reads plain BMP.

03

A small banner

Even a 30 KB 1200×400 banner becomes a 1.37 MB BMP, since BMP size depends only on the pixel count, not on what the picture shows.

FAQ

Frequently asked questions

Quick answers to common questions about the JPG to BMP Converter.

How do I convert JPG to BMP?

Upload your JPG image(s) above — the format is already preset to JPG to BMP — then click Convert. Each file converts entirely in your browser.

Is this JPG to BMP converter free?

Yes. It's free, with no sign-up and no limit on how many images you convert.

Why would I need a BMP instead of a JPG?

BMP is an uncompressed format that stores every pixel directly, so files are large but there is zero quality loss — some older software, embedded devices and hardware tools specifically require it.

Will the BMP file be much larger than the JPG?

Yes, usually significantly larger — BMP stores every pixel with no compression at all, while JPG compresses the image, so the size difference can be dramatic for photos.

Are my images uploaded to a server?

No. BMP files are written directly in your browser byte-by-byte, with no library needed — your images never leave your device.

Can I convert BMP back to JPG?

Yes — use the dedicated BMP to JPG converter page, or just swap the format dropdowns here.

What kind of BMP does it create?

A standard 24-bit uncompressed BMP — the most widely supported variant, which opens in Windows Paint, older image editors and most embedded or industrial software. There's no colour palette and no compression.

Does the BMP keep the photo's EXIF data?

No. The image is redrawn and saved as plain pixels, so EXIF metadata — the camera model, the date and any GPS location — isn't copied into the BMP.

Does converting improve the quality of my JPG?

No. The BMP stores the JPG's pixels exactly, including any compression artefacts already in the photo. It only stops further loss if you edit and re-save the image.
