Convert BMP images to JPG format directly in your browser — no upload, no signup, no watermark. BMP files are uncompressed, which means a typical 4000×3000 BMP is 36MB. The same image as JPG at high quality is under 2MB — a 95% size reduction with no visible quality loss for photos. If you've inherited a folder of BMP files from a Windows app or an old scanner, JPG is the quickest way to make them shareable. Drop one file or a whole folder, and the converter produces JPG files you can download immediately.

About BMP and JPG
BMP is an uncompressed Windows format from the early 1990s — every pixel is stored verbatim, which produces gigantic files. It works in opens in any Windows image viewer, but most modern web platforms and CMSes reject it, and is best suited for almost nothing modern — it's a legacy format you usually want to convert away from. JPG is a lossy compressed format that produces small files for photographs. It works in every browser, OS, image editor, email client, and printing service ever made, and is best suited for photographs and complex color images headed to email, social media, or print.
Quality and file size
BMP stores every pixel losslessly. Converting to JPG introduces lossy compression, which is what makes the output dramatically smaller. At a quality setting around 85, the visual result is virtually indistinguishable from the source for natural photographs. For text, line art, or sharp edges, expect some softening — that's the trade-off for the size reduction.
Transparency and backgrounds
Neither BMP nor JPG stores transparency for standard photos, so this is a straightforward photo-format conversion — no transparency-related surprises.
Privacy: where the conversion happens
The conversion runs entirely in your browser using the built-in canvas encoders. Your BMP files are never uploaded to any server, never stored, and never logged. That matters when you're converting passports, IDs, medical scans, financial documents, or anything else you wouldn't paste into a stranger's web form. Drop in dozens of files at once — there's no per-file count, no quota, and no watermark on the output.
