How do I convert WebP to BMP?

Add your WebP file to the upload area above, then press Convert. The BMP file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to BMP reduce quality?

No. BMP is a lossless format, so the conversion preserves exactly what is in your WebP file. Note that it cannot recover detail that was already discarded when the WebP was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

WebP and BMP explained

WebP is a Google-developed format that offers both lossy and lossless modes, transparency, and animation in one container. In its lossy mode it typically produces files around 25–35% smaller than JPEG at comparable visual quality.

BMP stores pixels essentially raw, with little or no compression. A 1920×1080 BMP is around 6 MB regardless of what the picture contains, because every pixel takes the same space whether it is part of a gradient or a flat colour.

Where WebP files come from: Modern websites, and increasingly the default export from web-focused design tools.
Where BMP is used: Legacy Windows software, some scientific and industrial imaging tools.

WebP vs BMP

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

WebP compared with BMP
Property	Source	Target
Compression	Lossy or lossless	Uncompressed
Transparency	Yes	No
Animation	Yes	No
Introduced	2010	1990
Browser support	All modern browsers. Some older desktop apps can't open it.	Broad, though rarely the best choice today.

WebP is stronger at: Substantially smaller than JPEG at similar quality. Supports transparency, which JPEG cannot. Supports animation, replacing GIF at a fraction of the size.
BMP is stronger at: Trivially simple to read and write. No compression artefacts whatsoever. Still readable by very old software.

Why convert WebP to BMP?

People make this switch when they run into the limits of WebP: the file needs to be opened by arbitrary desktop software, emailed to non-technical recipients, or sent to a print shop. BMP is the better fit when a legacy application specifically requires it.

Be aware of the size trade-off: BMP is uncompressed, so expect the converted file to be considerably larger than the WebP you started with.

WebP limitations that prompt the switch: Desktop applications and older software often cannot open it. Some photo printing services and older phones reject it. Lossy WebP, like JPEG, degrades on re-save.
What you give up: Enormous files. No standard support for transparency in most variants.

Does converting WebP to BMP reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.

WebP is not always smaller. For simple graphics with few colours, a well-optimised PNG can still win.
