About Bitmap

Bitmap (BMP) has been around since 1990 and stores images with 16.7 million colours, with none (or 8-bit) transparency support. An uncompressed Windows bitmap that keeps every original pixel makes it the right choice for raw pixel-exact storage and legacy windows pipelines. The 9 converters on this page move BMP files into whichever of the other ten formats your destination needs, for example BMP to WebP, BMP to JPG, BMP to AVIF.

Coming from the other direction? The reverse tools are one click away: WebP to BMP, JPG to BMP, PNG to BMP

BMP Converter FAQ

Is bmp converter use on this site free?
Yes — every bmp converter tools on the list above is free with unlimited use: no credits, no account, no watermarks and no file caps. Batches run up to 30 images at a time.
Do I need to upload my files anywhere?
No. Each tool processes images locally in your browser using Canvas and WebAssembly, so your files never travel to a server. That keeps client work, documents and personal photos private by default.
Can I convert BMP files on iPhone and Android?
Yes — Safari on iOS and Chrome on Android both run this page fully. BMP files stored in your phone's Photos library or Files app can be dropped straight in and converted.
How fast is the processing?
Typically a fraction of a second per photo on a laptop and a couple of seconds per phone image. Because there is no upload round-trip, a 10MB file converts almost as quickly as a 100KB one — the only limit is your device.
Can I do 9 different jobs here?
All of them: pick any tool above and it opens a dedicated page with its own options, examples and FAQ. The tools share one interface, so learning one means knowing them all.
Will converting reduce my image quality?
Lossless targets (PNG, BMP, TIFF, GIF) are pixel-exact by definition. For photo formats you control the quality slider, which defaults to 92% — visually indistinguishable from the original on most content. Resolution is always preserved unless you ask for a size cap.
Do I need to install anything or make an account?
Never. There is nothing to download and no sign-up form — open any tool above and it is ready instantly. Your browser is the only requirement, so the same tools work the same way on Windows, macOS, Linux, Chromebook, iPhone and Android.
Where do I start if I am new here?
Open the image format guide (linked in the site menu) for a plain-English explanation of every format and when to use it, or browse the full 220-tool directory to see how these 9 tools fit into the wider set.
