Convert BMP to JPG or PNG — Shrink Huge Bitmap Files

Where BMP files come from

BMP (bitmap) dates back to early Windows. It still turns up from legacy business software, older versions of Paint, microscopes and lab, medical or industrial instruments, POS and kiosk systems, some scanners and game screenshot tools.

Why they're so big

BMP usually stores every pixel's color without compression: a single 1920×1080 screen is around 6 MB, and high-resolution photos run to tens of megabytes. PNG shrinks the same image with no quality loss, and JPG usually makes it far smaller. Many websites, chat apps and upload forms don't accept BMP at all.

JPG or PNG?

JPG: photos and camera images — the biggest size reduction. Set quality under “Options”; 80–90% is plenty.

PNG: screenshots, charts, instrument graphs and anything with text. Lossless, so it's pixel-identical to the original.

For even smaller web images, WEBP is a good option too.

How to convert

1) Drop BMP files into anyview.dev or tap “Choose files”. 2) Click JPG or PNG — each converts and downloads immediately. 3) For several, use “Download all (ZIP)”; the free version handles up to 20 files per batch.

Everything runs in your browser, so work or medical images never leave your device. To bundle several into a report, click PDF to make one file.
