BMP vs WEBP: what changes when you convert
BMP (Bitmap Image File) was introduced in 1987 by Microsoft and is best known for legacy windows applications. WEBP (WebP), created by Google, is the better choice when you need website images — smaller than jpg and png at the same quality.
Why convert? WEBP files are typically much smaller than BMP — expect a noticeable reduction in file size.
Upload one file or a whole batch — conversion happens over a secure HTTPS connection and finished files are automatically deleted from our servers within minutes. Some older apps, email clients, and Windows photo viewers still cannot open WebP files.
