Why is my BMP so large compared to JPG?

BMP stores every pixel uncompressed — a 1080p image is about 6 MB. JPG compresses photographic content to typically 200–500 KB at quality 90, with no visible difference.

Can I still open BMPs on Mac / Linux?

Most modern image viewers can open BMP, but many email systems, messaging apps, and web forms reject it. Converting to JPG ensures it works everywhere.

Does it work for 24-bit and 32-bit BMP?

Yes — sharp decodes both. Alpha pixels in 32-bit BMP are flattened to white because JPG has no alpha channel.

About BMP to JPG

BMP (Windows Bitmap) is an uncompressed legacy format — a 1080p image is around 6 MB, where the equivalent JPG is 200–500 KB. BMP is no longer accepted by most email clients, web upload forms, messaging apps, or modern image viewers on Mac and Linux. Converting to JPG shrinks the file dramatically and makes it openable everywhere. This tool decodes BMP server-side and re-encodes at your chosen JPEG quality.
