Why convert BMP to WebP?
WebP produces noticeably smaller files than JPG or PNG, which makes web pages load faster and saves storage.
About the formats
BMP. BMP is an uncompressed bitmap format from Windows. Files are very large and it is rarely used on the web.
WebP. WebP is a modern image format from Google that produces smaller files than JPG or PNG at similar quality. Some older software and upload forms still reject it.
Private by design
Most online converters upload your files to a remote server. LocalConvert does the work in your browser, so photos, contracts and spreadsheets never leave your device. There is nothing to install and it works on Windows, Mac, Android and iPhone.
Frequently asked questions
Is this BMP to WebP converter free?
Yes. There are no sign-ups, watermarks or daily limits. Convert as many files as you like.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using your own device, so your files never leave your computer or phone. That also makes it fast, and it works for private documents.
Is there a file size limit?
There is no fixed limit. The practical limit is your device memory. Files up to a few hundred megabytes usually work fine on a modern laptop.
Will I lose quality?
WebP uses lossy compression. Use the quality slider: 90% and above is visually indistinguishable from the original for most photos, while lower values give smaller files.
