Runs on your device. Images are read and converted in your browser and aren't uploaded.

BMP

Uncompressed
Windows
Big files

Windows' plain bitmap: every pixel stored as it is, with no compression, so files are big and predictable. Paint, older Windows software and some machines and embedded displays still expect BMP. The usual 24-bit kind has no transparency; 32-bit can carry it.

A BMP is uncompressed, so as PNG or TIFF every opaque pixel is kept exactly, and as WebP or JPG it's compressed at the Quality you choose — usually much smaller, with detail you're unlikely to notice left out. As GIF it's cut to 256 colours or fewer.

Transparency is kept as WebP, PNG and TIFF, and all or nothing as GIF; JPG and 24-bit BMP fill it with the Background colour.
Choosing BMP itself re-encodes it — to resize it or strip its metadata.
BMP files can be up to 256 MB and 268 megapixels.
WebP is made by the browser's own encoder in Chrome, Edge and Firefox and by libwebp (WebAssembly) in Safari; PNG and JPG by the browser; GIF, TIFF and BMP by the tool itself — so every format can be made in every modern browser.
Camera details, location and other metadata are removed, and so is any colour profile: colours are converted to sRGB. A photo's orientation is applied first, so it stays the right way up.

How to do it

Choose your BMP files, or drop or paste them on the page — as many as you like.
Each starts as a WebP; pick another format for every file with Convert to in Settings, or for one file on its row.
Convert all, then download each image, or all of them in one .zip.
