When to convert BMP to WEBP
Uncompressed Windows bitmap. Large files, so PNG output is usually the better choice.
WEBP is usually 25 to 35 percent smaller than JPG at the same visual quality, which makes web pages load faster.

Questions
Is converting BMP to WEBP free?
Yes. Conversion runs in your browser on every plan, with no account, no watermark and batches of up to 200 files.
Are my BMP files uploaded?
No. The browser decodes each file and encodes the new one on your device. Nothing is sent to a server.
Does converting BMP to WEBP lose quality?
WEBP is lossy at the quality you pick. At 80 to 90 it looks the same as the source for photos and is much smaller.
Can I make the WEBP bigger at the same time?
Converting keeps the pixel size. To enlarge, run the upscaler afterwards: 2× is free and also runs on your device.
