Convert images, documents, video and audio in your browser. Your files stay on your device.
Need the image as WEBP because a website, an app or a printer won’t take BMP? Drop the files here: the conversion runs on your own device, even for dozens of images at once.
Drag one or more BMP files onto the dashed area, or tap it to pick them from your device.
WEBP is already selected; the options hold the settings that matter for this conversion.
Press “Convert to WEBP”. When it’s done, download the files one by one or all together in a ZIP archive.
Good to know. In the options you can also resize, rotate or turn all the images black and white in one go.
Source format
BMP (Windows Bitmap)
The historic Windows format: it stores pixels almost always without any compression. It’s simple and faithful, but a Full HD image easily exceeds 6 MB. Scanners, old software and some industrial machines still produce it.
Target format
WebP (developed by Google)
A format designed for the web: at the same quality it’s on average 25-35% lighter than JPG and PNG, and it also supports transparency and animation. Every modern browser shows it, but some graphics programs and online services still don’t accept it.
No. The conversion from BMP to WEBP happens entirely in your browser, using your device’s computing power. Files aren’t sent or stored anywhere: when you close the page they’re gone from memory too.
Up to 100 files at a time. There’s no fixed size limit: it depends on your device’s memory. On smartphones it’s best to work in smaller batches with heavy files such as videos.
Yes, with up-to-date Safari, Chrome, Firefox, Edge and Samsung Internet. On phones, converted files end up in the Downloads folder or the Files app.
For photos to share or post online, a quality between 75 and 85 gives light files with no visible flaws. For print or archiving go up to 90-95.
Only to open the page (and, the first time, to download the components needed for that type of file). After that the conversion keeps working even if the connection drops.
