An uncompressed BMP converted to WebP at quality 92 usually shrinks by 20–40×, and the result is a format every modern browser displays. The bitmap is decoded in your browser and encoded once; nothing is uploaded.
WebP keeps transparency if the BMP has an alpha channel, and its compression handles both photographs and flat-colour graphics well, so it is a reasonable single choice when you do not want to decide between JPG and PNG.
WebP is for the web. If the image is headed into a Word document, a print job or an older mail client, BMP to JPG or BMP to PNG is the safer format. If it is going onto a website or into an app, WebP is the one that loads fastest.
No. The conversion runs entirely in your browser using JavaScript — your file never leaves your device, so it's safe even for sensitive documents.
Yes — completely free, no signup, no watermark, and no daily limits.
No. The converter writes lossy WebP at quality 92, which is visually equivalent for photos and screenshots. For a lossless copy use BMP to PNG.
Typically 25–35% smaller at the same visual quality.
