Can I convert WebP to BMP on iPhone, Android, Mac or Windows?

Yes. ConvertPixels works in Safari, Chrome, Edge and Firefox on any device, so you can convert WebP to BMP on your phone or computer without installing an app.

Is there a free WebP to BMP converter with no sign-up?

Yes, this one. Converting WebP to BMP on ConvertPixels is free, with no sign-up, no watermark and no daily cap. Convert up to 30 files per batch, each up to 50 MB.

Can I convert WebP to BMP without losing quality?

Yes. BMP is a lossless format, so your converted file is pixel-for-pixel the same as the WebP. (It can't add back detail the original never had.)

Does BMP keep the transparent background of my WebP?

No - BMP has no transparency, so see-through areas get a solid fill. That's white unless you pick another background color in the options.

Can I convert an animated WebP to BMP?

BMP only stores still images, so you'll get the first frame. To keep the animation, convert to GIF or WebP instead.

Can I batch convert WebP to BMP?

Yes. Add up to 30 WebP files and convert them in one batch. You can even choose a different output format for individual files, then download them separately or together as a ZIP.

Is it safe to upload WebP files to ConvertPixels?

Yes. Uploads use an encrypted connection and are processed automatically - nobody views them. Your originals are deleted straight after conversion and the results within an hour, or instantly if you click "Delete from server now".

WebP to BMP

Why convert WebP to BMP?

The main difference: WebP is a lossy or lossless format, while BMP is a lossless format. WebP can have a transparent background, BMP can't.

Where BMP works best

BMP is ideal for legacy Windows software (files are very large). Converting gives you a file that works in the apps and websites that ask for BMP.

WebP vs BMP: what's the difference?

Property	WebP	BMP
Compression type	Lossy or lossless	Lossless (exact pixels, larger files)
Transparent background	Yes	No
Animation	Yes	No
Where it opens	All modern browsers; some older apps and upload forms don't accept it	Most browsers, rarely used on the web
Used for	Fast-loading website images	Legacy Windows software (files are very large)

What is a WebP file?

WebP is an image format Google introduced in 2010 to make websites load faster. It can compress photos lossily like JPG, or graphics losslessly like PNG - usually with 25-35% smaller files - and it supports transparency and animation too.

That's why so many images you save from websites, including Google Images, arrive as .webp files. Browsers love them; older software and many upload forms still don't.

How to open a WebP file

Chrome, Edge, Firefox and Safari display WebP directly - drag the file into a browser window. Windows 10/11 Photos and Paint and Mac Preview (Big Sur and later) open it as well. If an app or website rejects it, convert it to JPG or PNG.

Extension: .webp
Compression: Lossy or lossless
Transparency: Yes
Best for: Fast-loading website images

What is a BMP file?

BMP (bitmap) is Microsoft's original Windows image format. It stores pixels with little or no compression, so it's simple and lossless but very large - a 12-megapixel photo can top 35 MB.

BMP is mainly found in older Windows software, some industrial and embedded systems, and scanner output. For almost every other use, PNG gives the same quality at a fraction of the size.

How to open a BMP file

Windows Photos and Paint open BMP files, as does Mac Preview. Most browsers can display them too. Convert to PNG for a lossless copy that's much smaller, or JPG for photos.

Extensions: .bmp, .dib
Compression: None (usually)
Transparency: Rarely supported
Best for: Legacy Windows software
