Convert BMP to PNG

Converting BMP to PNG 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 PNG file (a .png) — no software to install, no account to create, and no watermark on the output.

What is BMP?

BMP is an uncompressed Windows bitmap — large files because nothing is compressed, but dead simple and universally readable on Windows.

What is PNG?

PNG is a lossless format that preserves every pixel and supports full alpha transparency — the standard for logos, icons, screenshots and any graphic with crisp edges or text. The trade-off is larger files than lossy formats for photographs.

Why convert BMP to PNG?

The usual reason to convert BMP to PNG is file size or quality: PNG fits the job better, whether that means a smaller download, a cleaner edit, or broader support. 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.

BMP vs PNG: what changes

Because BMP is uncompressed, the PNG you get back will typically be dramatically smaller. Unlike BMP, PNG supports transparency, so it's a good target if you later need a cut-out.

When you'd convert BMP to PNG

Typical uses: preparing assets for a website, attaching a file someone else can definitely open, or standardising a folder of mixed files into one format.

Is it private?

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.
