JPG vs BMP: what changes when you convert
JPG (JPEG (Joint Photographic Experts Group)) was introduced in 1992 by the Joint Photographic Experts Group and is best known for photos, social media, email attachments. BMP (Bitmap Image File), created by Microsoft, is the better choice when you need legacy windows applications.
Why convert? BMP files are usually larger than JPG, but you gain legacy windows applications.
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. BMP stores raw uncompressed pixels — files are enormous compared with any modern format.
