Free online BMP→WebP converter. Fast, private, no sign-up.
Converting BMP to WebP is one of those small tasks that should be instant and free — and here it is. Drop in your BMP file (a .bmp) and download a ready-to-use WebP file (a .webp) — no software to install, no account to create, and no watermark on the output.
BMP is an uncompressed Windows bitmap — large files because nothing is compressed, but dead simple and universally readable on Windows.
WebP is a modern Google format doing both lossy and lossless with transparency, typically 25–35% smaller than JPEG or PNG at equivalent quality, supported by every current browser.
You'll reach for a BMP to WebP conversion whenever the other end expects WebP specifically — uploading somewhere, importing into software, or sharing with someone whose device prefers it. Under the hood the conversion runs on libvips and ImageMagick — the same libraries that power image pipelines across the web — so colour, transparency and metadata are handled correctly wherever the target format supports them.
Because BMP is uncompressed, the WebP you get back will typically be dramatically smaller. Unlike BMP, WebP supports transparency, so it's a good target if you later need a cut-out.
It comes up when publishing online, submitting to a service with strict format rules, or archiving a collection in a single consistent format.
Privacy is the default here. Your BMP file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
